FatFs - Generic FAT File System Module

-
- -
-layer -

FatFs is a generic FAT file system module for small embedded systems. The FatFs is written in compliance with ANSI C and completely separated from the disk I/O layer. Therefore it is independent of hardware architecture. It can be incorporated into small microcontrollers with limited resource, such as AVR, 8051, PIC, ARM, Z80, 68k and etc... Petit FatFs module is also available here↗ for tiny microcontrollers.

-

Disk I/O Interface

-

Since the FatFs module is completely separated from disk I/O layer, it requires following functions to access the storage device. When O/S related feature is enabled, it will require process/memory functions in addition. However the low level disk I/O module is not a part of FatFs module, so that it must be provided by user. The sample implementations are also available in the downloads.

Basic considerations

-

The FatFs module is assuming following conditions on portability.

- - -

System organizations

-

The dependency diagram shown below is a typical configuration of the embedded system with FatFs module.

-

-

(a) If a working disk module with FatFs API is provided, no additional function is needed. (b) To attach existing disk drivers with different API, glue functions are needed to translate the APIs between FatFs and the drivers.

-

Which function is required?

-

You need to provide only low level disk I/O functions that required by FatFs module and nothing else. If a working disk module for the target is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. Most of defined functions are not that always required. For example, disk write function is not required in read-only configuration. Following table shows which function is required depends on configuration options.

Long File Name

-

FatFs module supports long file name (LFN). The two different file names, SFN and LFN, of a file is transparent in the file functions except for f_readdir() function. The LFN feature is disabled by default. To enable it, set _USE_LFN to 1, 2 or 3, and add option/unicode.c to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by _MAX_LFN according to the available memory size. The size of long file name will reach up to 255 characters, so that the _MAX_LFN should be set to 255 for full featured LFN operation. If the size of working buffer is insufficient for the given file name, the file function fails with FR_INVALID_NAME. When enable the LFN feature with re-entrant configuration, _USE_LFN must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies (_MAX_LFN + 1) * 2 bytes.

- - - - - - - - -
LFN cfg on ARM7TDMI
Code pageProgram size
SBCS+3.7K
932(Shift-JIS)+62K
936(GBK)+177K
949(Korean)+139K
950(Big5)+111K
-

When the LFN feature is enabled, the module size will be increased depends on the selected code page. Right table shows how many bytes increased when LFN feature is enabled with some code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN feature with those code pages will not able to be implemented to most 8-bit microcontrollers.

-

Note that the LFN feature on the FAT file system is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers come with the LFN feature. FatFs can swich the LFN feature off by configuration option. When enable LFN feature on the commercial products, a license from Microsoft may be required depends on the final destination.

-
- -
-

Unicode API

-

By default, FatFs uses ANSI/OEM code set on the API under LFN configuration. FatFs can also switch the character encoding to Unicode on the API (_LFN_UNICODE). This means the FatFs supports the True-LFN feature. For more information, refer to the description in the file name.

-
- -
-

Re-entrancy

-

The file operations to the different volume is always re-entrant and can work simultaneously. The file operations to the same volume is not re-entrant but it can also be configured to thread-safe with _FS_REENTRANT option. In this case, also the OS dependent synchronization object control functions, ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant() and ff_rel_grant() must be added to the project.

-

When a file function is called while the volume is in use by any other task, the file function is suspended until that task leaves file function. If wait time exceeded a period defined by _TIMEOUT, the file function will abort with FR_TIMEOUT. The timeout feature might not be supported by some RTOS.

-

There is an exception for f_mount(), f_mkfs(), f_fdisk() function. These functions are not re-entrant to the same volume or corresponding physical drive. When use these functions, all other tasks must unmount the volume and avoid to access the volume.

-

Note that this section describes on the re-entrancy of the FatFs module itself but also the low level disk I/O layer will need to be re-entrant.

-
- -
-

Duplicated File Access

-

FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed and deleted. A violation of these rules can cause data colluption.

-

The file lock control can also be available by _FS_LOCK option. The value defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will fail with FR_LOCKED. If number of open files and sub-directories gets larger than _FS_LOCK, the open function will fail with FR_TOO_MANY_OPEN_FILES.

-
- -
-

Performance Effective File Access

-

For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by f_read() function.

-

Figure 1. Sector misaligned read (short)
- -

-

Figure 2. Sector misaligned read (long)
- -

-

Figure 3. Fully sector aligned read
- -

-

The file I/O buffer is a sector buffer to read/write a partial data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the file system object. The buffer configuration option _FS_TINY determins which sector buffer is used for the file data transfer. When tiny buffer (1) is selected, data memory consumption is reduced 512 bytes each file object. In this case, FatFs module uses only a sector buffer in the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.

-

Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with disk_read() function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.

-

Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.

-

-

Considerations on Flash Memory Media

-

To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.

-

Using Mutiple-Sector Write

-
-Figure 6. Comparison between Multiple/Single Sector Write
-fig.6 -
-

The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. This graph is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. The number of write transactions also affects the life time of the flash memory media. Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write feature.

-

Forcing Memory Erase

-

When remove a file with f_remove() function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data is forced erased on removing the file, those data blocks will be turned in to the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this feature by setting _USE_ERASE to 1. Note that this is an expectation of internal process of the flash memory storage and not that always effective. Also f_remove() function will take a time when remove a large file. Most applications will not need this feature.

-
- -
-

Critical Section

-

If a write operation to the FAT volume is interrupted due to any accidental failure, such as sudden blackout, incorrect disk removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.

-
-Figure 4. Long critical section
-fig.4 -
-
-Figure 5. Minimized critical section
-fig.5 -
-
-

An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.

- -

Each case does not affect the files that not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using f_sync() function as shown in Figure 5.

Long File Name

+

FatFs module supports LFN (long file name). The two different file names, SFN (short file name) and LFN, of a file is transparent on the API except for f_readdir() function. The LFN feature is disabled by default. To enable it, set _USE_LFN to 1, 2 or 3, and add option/unicode.c to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by _MAX_LFN according to the available memory. The length of an LFN will reach up to 255 characters, so that the _MAX_LFN should be set to 255 for full featured LFN operation. If the size of working buffer is insufficient for the input file name, the file function fails with FR_INVALID_NAME. When enable the LFN feature with re-entrant configuration, _USE_LFN must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies (_MAX_LFN + 1) * 2 bytes.

+ + + + + + + + +
LFN cfg on ARM7TDMI

SBCS+3.7K
932(Shift-JIS)+62K
936(GBK)+177K
949(Korean)+139K
950(Big5)+111K
+

When the LFN feature is enabled, the module size will be increased depends on the selected code page. Right table shows how many bytes increased when LFN feature is enabled with some code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN feature with those code pages will not able to be implemented to most 8-bit microcontrollers.

+

Note that the LFN feature on the FAT file system is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers come with the LFN feature. FatFs can swich the LFN feature off by configuration option. When enable LFN feature on the commercial products, a license from Microsoft may be required depends on the final destination.

+
+ +
+

Unicode API

+

By default, FatFs uses ANSI/OEM code set on the API under LFN configuration. FatFs can also switch the character encoding to Unicode on the API by _LFN_UNICODE option. This means that the FatFs supports the True-LFN feature. For more information, refer to the description in the file name.

+
+ +
+

Re-entrancy

+

The file operations to the different volume is always re-entrant and can work simultaneously. The file operations to the same volume is not re-entrant but it can also be configured to thread-safe by _FS_REENTRANT option. In this case, also the OS dependent synchronization object control functions, ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant() and ff_rel_grant() must be added to the project. There are some examples in the option/syscall.c.

+

When a file function is called while the volume is in use by any other task, the file function is suspended until that task leaves the file function. If wait time exceeded a period defined by _TIMEOUT, the file function will abort with FR_TIMEOUT. The timeout feature might not be supported by some RTOS.

+

There is an exception for f_mount(), f_mkfs(), f_fdisk() function. These functions are not re-entrant to the same volume or corresponding physical drive. When use these functions, all other tasks must unmount the volume and avoid to access the volume.

+

Note that this section describes on the re-entrancy of the FatFs module itself but also the low level disk I/O layer will need to be re-entrant.

+
+ +
+

Duplicated File Access

+

FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed and deleted. A violation of these rules can cause data colluption.

+

The file lock control can also be available by _FS_LOCK option. The value defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will fail with FR_LOCKED. If number of open objects, files and sub-directories, gets larger than _FS_LOCK, the f_open(), f_optndir() function will fail with FR_TOO_MANY_OPEN_FILES.

+
+ +
+

Performance Effective File Access

+

For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by f_read() function.

+

Figure 1. Sector misaligned read (short)
+ +

+

Figure 2. Sector misaligned read (long)
+ +

+

Figure 3. Fully sector aligned read
+ +

+

The file I/O buffer is a sector buffer to read/write a partial data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the file system object. The buffer configuration option _FS_TINY determins which sector buffer is used for the file data transfer. When tiny buffer (1) is selected, data memory consumption is reduced 512 bytes each file object. In this case, FatFs module uses only a sector buffer in the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.

+

Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with disk_read() function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.

+

Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.

+
+ +
+

Considerations on Flash Memory Media

+

To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.

+

Using Mutiple-Sector Write

+
+Figure 6. Comparison between Multiple/Single Sector Write
+fig.6 +
+

The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. This graph is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. The number of write transactions also affects the life time of the flash memory media. Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write feature.

+

Forcing Memory Erase

+

When remove a file with f_remove() function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data is forced erased on removing the file, those data blocks will be turned in to the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this feature by setting _USE_ERASE to 1. Note that this is an expectation of internal process of the flash memory storage and not that always effective. Also f_remove() function will take a time when remove a large file. Most applications will not need this feature.

+
+ +
+

Critical Section

+

If a write operation to the FAT volume is interrupted due to any accidental failure, such as sudden blackout, incorrect disk removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.

+
+Figure 4. Long critical section
+fig.4 +
+
+Figure 5. Minimized critical section
+fig.5 +
+
+

An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.

+ +

Each case does not affect the files that not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using f_sync() function as shown in Figure 5.

Description

-

The FatFs module requires only five device independent commands described below.

- - - - - - - - -
Standard ioctl command used by FatFs
CommandDescription
CTRL_SYNCMake sure that the device has finished pending write process. If the disk I/O module has a write back cache, the dirty buffers must be written back to the media immediately. Nothing to do for this command if each write operation to the media is completed within the disk_write() function. Required at _FS_READONLY == 0.
GET_SECTOR_COUNTReturns number of available sectors on the drive into the DWORD variable pointed by buff. This command is used by only f_mkfs() and f_fdisk() function to determine the volume/partition size to be created. Required at _USE_MKFS == 1 or _MULTI_PARTITION == 1.
GET_SECTOR_SIZEReturns sector size of the media into the WORD variable pointed by buff. Valid return values of this command are 512, 1024, 2048 or 4096. This command is required at variable sector size configuration, _MAX_SS > _MIN_SS. Never used at fixed sector size configuration, _MAX_SS == _MIN_SS, and it must work at that sector size.
GET_BLOCK_SIZEReturns erase block size of the flash memory in unit of sector into the DWORD variable pointed by buff. The allowable value is from 1 to 32768 in power of 2. Return 1 if the erase block size is unknown or disk media. This command is used by only f_mkfs() function and it attempts to align data area to the erase block boundary. Required at _USE_MKFS == 1.
CTRL_ERASE_SECTORInforms device that the data on the block of sectors specified by a DWORD array {<start sector>, <end sector>} pointed by buff is no longer needed and may be erased. The device would force erased the memory block. This is a command similar to Trim command of ATA device. When this feature is not supported or not a flash memory media, nothing to do for this command. The FatFs does not check the result code and the file function is not affected even if the sectors ware not erased well. This command is called on removing a cluster chain and f_mkfs() function. Required at _USE_ERASE == 1.
- -

FatFs never uses any device dependent command and user defined command. Following table shows an example of non-standard commands usable for some applications.

- - - - - - - - - - - - - - - - - -
Example of optional ioctl command
CommandDescription
CTRL_FORMATCreate a physical format on the media. If buff is not null, it is pointer to the call-back function for progress notification.
CTRL_POWER_IDLEPut the device idle state. STA_NOINIT in status flag may not be set if the device would go active state by generic read/write function.
CTRL_POWER_OFFPut the device off state. Shut-down the power to the device and deinitialize the device interface if needed. STA_NOINIT in status flag must be set. The device goes active state by disk_initialize() function.
CTRL_LOCKLock media eject mechanism.
CTRL_UNLOCKUnlock media eject mechanism.
CTRL_EJECTEject media cartridge. STA_NOINIT and STA_NODISK in status flag are set after the function succeeded.
MMC_GET_TYPEGet card type. The type flags, bit0:MMCv3, bit1:SDv1, bit2:SDv2+ and bit3:LBA, is stored to a BYTE variable pointed by buff. (MMC/SDC specific command)
MMC_GET_CSDGet CSD register into a 16-byte buffer pointed by buff. (MMC/SDC specific command)

Path Names

- -
-

Format of the path names

-

The format of path name on the FatFs module is similer to the filename specs of DOS/Windos as follows:

-
"[drive:][/]directory/file"
-

The FatFs module supports long file name (LFN) and 8.3 format file name (SFN). The LFN can be used when LFN feature is enabled (_USE_LFN > 0). The sub directories are separated with a \ or / in the same way as DOS/Windows API. Duplicated separators are skipped and ignored. Only a difference is that the logical drive is specified in a numeral with a colon. When drive number is omitted, the drive number is assumed as default drive (drive 0 or current drive).

-

Control characters ('\0' to '\x1F') are recognized as end of the path name. Leading/embedded spaces in the path name are valid as a part of the name at LFN configuration but they are recognized as end of the path name at non-LFN configuration. Trailing spaces and dots are ignored.

-

In default configuration (_FS_RPATH == 0), it does not have a concept of current directory like OS oriented file system. All objects on the volume are always specified in full path name that follows from the root directory. Dot directory names are not allowed. Heading separator is ignored and it can be exist or omitted. The default drive is fixed to drive 0.

-

When relative path feature is enabled (_FS_RPATH == 1), specified path is followed from the root directory if a heading separator is exist. If not, it is followed from the current directory of the drive set with f_chdir function. Dot names are also allowed for the path name. The default drive is the current drive set with f_chdrive function.

Unicode API

-

The path names are input/output in either ANSI/OEM code (SBCS/DBCS) or Unicode depends on the configuration options. The type of arguments which specify the file names are defined as TCHAR. It is an alias of char in default. The code set used to the file name string is ANSI/OEM specifid by _CODE_PAGE. When _LFN_UNICODE is set to 1, the type of the TCHAR is switched to WCHAR to support Unicode (UTF-16 encoding). In this case, the LFN feature is fully supported and the Unicode specific characters, such as ✝☪✡☸☭, can also be used for the path name. It also affects data types and encoding of the string I/O functions. To define literal strings, _T(s) and _TEXT(s) macro are available to select either ANSI/OEM or Unicode automatically. The code shown below is an example to define the literal strings.

-
- f_open(fp, "filename.txt", FA_READ);      /* ANSI/OEM string */
- f_open(fp, L"filename.txt", FA_READ);     /* Unicode string */

Volume Management

-

The FatFs module needs dynamic work area called file system object for each volume (logical drive). It is registered to the FatFs module by f_mount() function. By default, each logical drive is bound to the physical drive with the same drive number and an FAT volume on the drive is serched by auto detect feature. It loads boot sectors and checks it if it is an FAT boot sector in order of sector 0 as SFD format, 1st partition, 2nd partition, 3rd partition and 4th partition as FDISK format.

-

When _MULTI_PARTITION == 1 is specified by configuration option, each individual logical drive is bound to the partition on the physical drive specified by volume management table. The volume management table must be defined by user to resolve relationship between logical drives and partitions. Following code is an example of a volume management table.

-
-Example: Logical drive 0-2 are tied to three pri-partitions on the physical drive 0 (fixed disk)
-         Logical drive 3 is tied to an FAT volume on the physical drive 1 (removable disk)
-
-PARTITION VolToPart[] = {

Description

-

The f_forward() function reads the data from the file and forward it to the outgoing stream without data buffer. This is suitable for small memory system because it does not require any data buffer at application module. The file pointer of the file object increases in number of bytes forwarded. In case of *bf is less than btf without error, it means the requested bytes could not be transferred due to end of file or stream goes busy during data transfer.

Description

-

The f_lseek() function moves the file read/write pointer of an open file. The offset can be specified in only origin from top of the file. When an offset beyond the file size is specified in write mode, the file size is expanded to the specified offset. The file data in the expanded area is undefined because no data is written to the file. This is suitable to pre-allocate a cluster chain quickly, for fast write operation. After the f_lseek() function succeeded, the current read/write pointer should be checked in order to make sure the read/write pointer has been moved correctry. In case of the current read/write pointer is not the expected value, either of followings has been occured.

- -

Fast seek feature is enabled when _USE_FASTSEEK is set to 1 and the member cltbl in the file object is not NULL. This feature enables fast backward/long seek operations without FAT access by using CLMT (cluster link map table). The fast seek feature is also applied to f_read()/f_write() function, however, the file size cannot be expanded by f_write()/f_lseek() function.

-

The CLMT must be created in the user defined DWORD array prior to use the fast seek feature. To create the CLMT, set address of the DWORD array to the member cltbl in the file object, set the array size in unit of items into the first item and call the f_lseek() function with ofs = CREATE_LINKMAP. After the function succeeded and CLMT is created, no FAT access is occured at subsequent f_read()/f_write()/f_lseek() function to the file. If the function failed with FR_NOT_ENOUGH_CORE, the given array size is insufficient for the file and number of items required is returned into the first item of the array. The required array size is (number of fragments + 1) * 2 items. For example, when the file is fragmented in 5, 12 items will be required for the CLMT.

Description

-

The f_mkfs() function creates an FAT volume on the logical drive. When FDISK format is specified, a primary partition occupies the entire disk space is created and then an FAT volume is created on the partition. When SFD format is specified, the FAT volume starts from the first sector of the physical drive.

-

If the logical drive has been bound to any partition (1-4) by multiple partition feature (_MULTI_PARTITION), the FAT volume is created into the specified partition. In this case, the second argument sfd is ignored. The physical drive must have been partitioned with f_fdisk() function or any other partitioning tool prior to use this function.

-

Note that there are two partitioning rules, FDISK and SFD. The FDISK partitioning is usually used for harddisk, MMC, SDC, CFC and U Disk. It can divide a physical drive into one or more partitions with a partition table on the MBR. However Windows does not support multiple partition on the removable media. The SFD is non-partitioned method. The FAT volume starts from the first sector on the physical drive without partition table. It is usually used for floppy disk, Microdrive, optical disk and super-floppy media.

-

The FAT sub-type, FAT12/FAT16/FAT32, is determined by number of clusters on the volume and nothing else, according to the FAT specification issued by Microsoft. Thus which FAT sub-type is selected, is depends on the volume size and the specified cluster size. The cluster size affects performance of the file system and large cluster increases the performance.

-

When the number of clusters gets near the FAT sub-type boundaries, the function can fail with FR_MKFS_ABORTED.

Description

-

The f_mount() function registers/unregisters a file system object used for the logical drive to the FatFs module as follows:

-
    -
  1. Determines the logical drive which specified by path.
    2. -
  2. Clears and unregisters the regsitered work area of the drive.
    3. -
  3. Clears and registers the new work area to the drive if fatfs is not NULL.
    4. -
  4. Performs volume mount process to the drive if forced mount is specified.
    5. -
-

The file system object is the work area needed for each logical drive. It must be given to the logical drive with this function prior to use any other file functions except for f_fdisk() function. To unregister a work area, specify a NULL to the fatfs, and then the work area can be discarded.

-

If forced mount is not specified, this function always succeeds regardless of the physical drive status due to delayed mount feature. It only clears (de-initializes) the given work area and registers its address to the internal table. No activity of the physical drive in this function. It can also be used to force de-initialized the registered work area of a logical drive. The volume mount processes, initialize the corresponding physical drive, find the FAT volume in it and initialize the work area, is performed in the subsequent file access functions when either or both of following condition is true.

- -

If the function with forced mount failed, it means that the file system object is registered but the volume is currently not available. Mount process will also be attempted in subsequent file access functions.

-

If implementation of the disk I/O layer lacks media change detection, application program needs to perform a f_mount() after each media change to force cleared the file system object.

ValueDescription
FA_READSpecifies read access to the object. Data can be read from the file. Combine with FA_WRITE for read-write access.
FA_WRITESpecifies write access to the object. Data can be written to the file. Combine with FA_READ for read-write access.
FA_OPEN_EXISTINGOpens the file. The function fails if the file is not existing. (Default)
FA_OPEN_ALWAYSOpens the file if it is existing. If not, a new file is created.
-To append data to the file, use f_lseek() function after file open in this method.
FA_CREATE_NEWCreates a new file. The function fails with FR_EXIST if the file is existing.
FA_CREATE_ALWAYSCreates a new file. If the file is existing, it will be truncated and overwritten.

Description

-

After f_open() function succeeded, the file object is valid. The file object is used for subsequent read/write functions to identify the file. To close an open file, use f_close() function. If the file is modified and not closed properly, the file data will be collapsed.

-

If duplicated file open is needed, read here carefully. However duplicated open of a file with write mode flag is always prohibited.

-

Before using any file function, a work area (file system object) must be registered to the logical drive with f_mount() function. All API functions except for f_fdisk() function can work after this procedure.

-

Return Code of the File Functions

-

On the FatFs API, most of file functions return common result code as enum type FRESULT. When a function succeeded, it returns zero, otherwise returns non-zero value that indicates type of error.

- -
-
FR_OK (0)
-
The function succeeded.
-
FR_DISK_ERR
-
An unrecoverable hard error occured in the lower layer, disk_read(), disk_write() or disk_ioctl() function.
Note that if once this error occured at any operation to an open file, the file object is aborted and all operations to the file except for close will be rejected.
-
FR_INT_ERR
-
Assertion failed. An insanity is detected in the internal process. One of the following possibilities are suspected. -
    -
  • There is any error of the FAT structure on the volume.
    • -
  • Work area (file system object, file object or etc...) is broken by stack overflow or any other application. This is the reason in most case.
    • -
-Note that if once this error occured at any operation to an open file, the file object is aborted and all operations to the file except for close will be rejected. -
-
FR_NOT_READY
-
The disk drive cannot work due to incorrect medium removal or disk_initialize() function failed.
-
FR_NO_FILE
-
Could not find the file.
-
FR_NO_PATH
-
Could not find the path.
-
FR_INVALID_NAME
-
The given string is invalid as the path name.
-
FR_DENIED
-
The required access was denied due to one of the following reasons: -
    -
  • Write mode open against the read-only file.
    • -
  • Deleting the read-only file or directory.
    • -
  • Deleting the non-empty directory or current directory.
    • -
  • Reading the file opened without FA_READ flag.
    • -
  • Any modification to the file opened without FA_WRITE flag.
    • -
  • Could not create the file or directory due to the directory table is full.
    • -
  • Could not create the directory due to the volume is full.
    • -
-
-
FR_EXIST
-
Name collision. Any object that has the same name is already existing.
-
FR_INVALID_OBJECT
-
The file/directory object structure is invalid or a null pointer is given. All open objects of the logical drive are invalidated by the voulme mount process.
-
FR_WRITE_PROTECTED
-
Any write mode action against the write-protected media.
-
FR_INVALID_DRIVE
-
Invalid drive number is specified in the path name. A null pointer is given as the path name. (Related option: _VOLUMES)
-
FR_NOT_ENABLED
-
Work area for the logical drive has not been registered by f_mount() function.
-
FR_NO_FILESYSTEM
-
There is no valid FAT volume on the drive.
-
FR_MKFS_ABORTED
-
The f_mkfs() function aborted before start in format due to a reason as follows: -
    -
  • The disk/partition size is too small.
    • -
  • Not allowable cluster size for this disk. This can occure when number of clusters gets near the boundaries of FAT sub-types.
    • -
  • There is no partition related to the logical drive. (Related option: _MULTI_PARTITION)
    • -
-
-
FR_TIMEOUT
-
The function was canceled due to a timeout of thread-safe control. (Related option: _TIMEOUT)
-
FR_LOCKED
-
The operation to the object was rejected by file sharing control. (Related option: _FS_LOCK)
-
FR_NOT_ENOUGH_CORE
-
Not enough memory for the operation. There is one of the following reasons: -
    -
  • Could not allocate a memory for LFN working buffer. (Related option: _USE_LFN)
    • -
  • Size of the given CLMT buffer is insufficient for the file fragments.
    • -
-
-
FR_TOO_MANY_OPEN_FILES
-
Number of open objects has been reached maximum value and no more object can be opened. (Related option: _FS_LOCK)

Return Code of the File Functions

+

On the FatFs API, most of file functions return common result code as enum type FRESULT. When a function succeeded, it returns zero, otherwise returns non-zero value that indicates type of error.

+ +
+
FR_OK (0)
+
The function succeeded.
+
FR_DISK_ERR
+
An unrecoverable hard error occured in the lower layer, disk_read(), disk_write() or disk_ioctl() function.
Note that if once this error occured at any operation to an open file, the file object is aborted and all operations to the file except for close will be rejected.
+
FR_INT_ERR
+
Assertion failed. An insanity is detected in the internal process. One of the following possibilities is suspected. +
    +
  • Work area (file system object, file object or etc...) is broken by stack overflow or any other application. This is the reason in most case.
    • +
  • There is any error of the FAT structure on the volume.
    • +
+Note that if once this error occured at any operation to an open file, the file object is aborted and all operations to the file except for close will be rejected. +
+
FR_NOT_READY
+
The disk drive cannot work due to incorrect medium removal or disk_initialize() function failed.
+
FR_NO_FILE
+
Could not find the file.
+
FR_NO_PATH
+
Could not find the path.
+
FR_INVALID_NAME
+
The given string is invalid as the path name.
+
FR_DENIED
+
The required access was denied due to one of the following reasons: +
    +
  • Write mode open against the read-only file.
    • +
  • Deleting the read-only file or directory.
    • +
  • Deleting the non-empty directory or current directory.
    • +
  • Reading the file opened without FA_READ flag.
    • +
  • Any modification to the file opened without FA_WRITE flag.
    • +
  • Could not create the file or directory due to the directory table is full.
    • +
  • Could not create the directory due to the volume is full.
    • +
+
+
FR_EXIST
+
Name collision. Any object that has the same name is already existing.
+
FR_INVALID_OBJECT
+
The file/directory object structure is invalid or a null pointer is given. All open objects of the logical drive are invalidated by the voulme mount process.
+
FR_WRITE_PROTECTED
+
Any write mode action against the write-protected media.
+
FR_INVALID_DRIVE
+
Invalid drive number is specified in the path name. A null pointer is given as the path name. (Related option: _VOLUMES)
+
FR_NOT_ENABLED
+
Work area for the logical drive has not been registered by f_mount() function.
+
FR_NO_FILESYSTEM
+
There is no valid FAT volume on the drive.
+
FR_MKFS_ABORTED
+
The f_mkfs() function aborted before start in format due to a reason as follows: +
    +
  • The disk/partition size is too small.
    • +
  • Not allowable cluster size for this disk. This can occure when number of clusters gets near the boundaries of FAT sub-types.
    • +
  • There is no partition related to the logical drive. (Related option: _MULTI_PARTITION)
    • +
+
+
FR_TIMEOUT
+
The function was canceled due to a timeout of thread-safe control. (Related option: _TIMEOUT)
+
FR_LOCKED
+
The operation to the object was rejected by file sharing control. (Related option: _FS_LOCK)
+
FR_NOT_ENOUGH_CORE
+
Not enough memory for the operation. There is one of the following reasons: +
    +
  • Could not allocate a memory for LFN working buffer. (Related option: _USE_LFN)
    • +
  • Size of the given CLMT buffer is insufficient for the file fragments.
    • +
+
+
FR_TOO_MANY_OPEN_FILES
+
Number of open objects has been reached maximum value and no more object can be opened. (Related option: _FS_LOCK)
+
FR_INVALID_PARAMETER
+
The given parameter is invalid or there is any inconsistent.

-
- -
-

Parameters

-
-
fp
-
Pointer to the open file object.
-
buff
-
Pointer to the buffer to store read data.
-
btr
-
Number of bytes to read in range of UINT type.
-
br
-
Pointer to the UINT variable to return number of bytes read. The value is always valid after the function call regardless of the result.

-FRESULT f_readdir (
-  DIR* dp,      /* [IN] Directory object */
-  FILINFO* fno  /* [OUT] File information structure */
-);
-

-

-FR_OK, -FR_DISK_ERR, -FR_INT_ERR, -FR_NOT_READY, -FR_INVALID_OBJECT, -FR_TIMEOUT, -FR_NOT_ENOUGH_CORE -

-
- - -
-

Description

-

The f_readdir() function reads directory items, file and directory, in sequence. All items in the directory can be read by calling f_readdir() function repeatedly. When relative path feature is enabled (_FS_RPATH >= 1), dot entries ("." and "..") are not filtered out and they will appear in the read items. When all directory items have been read and no item to read, a null string is returned into the fname[] without any error. When a null pointer is given to the fno, the read index of the directory object is rewinded.

-

When LFN feature is enabled, lfname and lfsize in the file information structure must be initialized with valid value prior to use it. The lfname is a pointer to the LFN read buffer. The lfsize is size of the LFN read buffer in unit of TCHAR. If the LFN is not needed, set a null pointer to the lfname and the LFN is not returned. A null string will be returned into the LFN read buffer in case of following conditions.

- -

When the directory item has no LFN information, lower case characters can be contained in the fname[].

-

f_setlabel

+

The f_setlabel function sets/removes the label of a volume.

Description

+

When the string has a drive number, the volume label will be set to the volume specified by the drive number. If not, the label will be set to the default drive. If the given string is a null-string, the volume label on the volume will be removed. The format of the volume label is similar to the short file name but there are some differences shown below:

Description

-

The f_sync() function performs the same process as f_close() function but the file is left opened and can continue read/write/seek operations to the file. This is suitable for the applications that open files for a long time in write mode, such as data logger. Performing f_sync() function of periodic or immediataly after f_write() function can minimize the risk of data loss due to a sudden blackout or an unintentional media removal. For more information, refer to application note.

-

However there is no sense in f_sync() function immediataly before f_close() function because it performs f_sync() function in it. In other words, the differnce between those functions is that the file object is invalidated or not.

ポーティングの際に配慮すべきこと

- -

移植の際の前提条件

-

FatFsモジュールは移植性に関して次の点を前提としています。

-
    -
  • 処理系はANSI C準拠であること。
    -FatFsモジュールはANSI C(C89)準拠で記述されているので、普通のCコンパイラなら特に処理系依存になる点はありません。
    • -
  • char/short/longのサイズは、それぞれ8/16/32ビットで、intは16または32ビットであること。
    -これについても、まっとうな処理系なら問題ないはずです。FatFsモジュールで使用されるサイズを明示する整数型が integer.h 内で定義されていますが、既存の定義と衝突した場合はユーザによって解決されなければなりません。
    • -
- -

システム構成

-

下に示す依存関係図は、FatFsモジュール利用の組み込みシステムにおける代表的な構成を示します。

-

システム構成図

-

(a) FatFs用に書かれたディスク・モジュールがある場合は、そのまま追加するだけです。 (b) しかし、多くの既存のディスク・モジュールはそのAPIをFatFsに合わせるため、グルー関数が必要になるでしょう。

ユーザの作成する関数

-

必要なのはFatFsモジュールの要求するディスク関数を用意することだけで、それ以外にすることはありません。既に動作しているディスク・モジュールがあるなら、そのAPIをFatFsに合わせるかグルー関数を介してつなぐだけで済みますが、無い場合はほかから移植するか最初から書くかする必要があります。定義されている全ての関数が常に必要なわけではありません。例えば、リード・オンリー構成では書き込み系関数は必要ありません。次の表に構成オプションと要求される関数の対応を示します。

長いファイル名

-

FatFsモジュールは、長いファイル名(LFN)をサポートします。ファイルに付けられた2つの異なる名前(短いファル名と長いファイル名)は、f_readdir()を除くファイル操作関数において透過です。デフォルト構成では、LFN機能はOFFになっています。LFN機能を有効にするには、_USE_LFNを1,2または3に設定し、option/unicode.cをプロジェクトに追加します。LFN機能は、加えてある程度のワーク・エリア(LFN操作バッファ)を必要とします。バッファ長は使用できるメモリに応じて_MAX_LFNオプションで構成されることができます。LFNの長さは最大255文字に達するので、LFN完全対応のためには_MAX_LFNは255に設定されるべきです。与えられたファイル名に対してバッファ長が不足した場合、ファイル関数はFR_INVALID_NAMEで失敗します。

-

ファイル関数に再入を行う条件の下でLFN機能を使用する場合は、_USE_LFNは2または3に設定されなければなりません。この場合、ファイル関数はワーク・エリアを動的に確保(スタックまたはヒープ)します。バッファ・サイズは、(_MAX_LFN + 1) * 2バイトになるので、スタック等のサイズはそれを考慮した十分なサイズでなければなりません。

- - - - - - - - -

936(GBK)+177797
949(Korean)+139857
950(Big5)+111497
-

LFN機能の上手な使い方は、それを使わないということです。実際、組み込み用途ではLFN機能がどうしても必要になるということはほとんど無いはずです。LFNを有効にすると、選択されたコード・ページに応じてモジュール・サイズが増大されます。右の表に各コード・ページにおけるLFNを有効にしたときのモジュール・サイズの違いを示します。特に、CJK地域では数万の文字が使われていますが、不幸なことにそれは巨大なOEM－Unicode相互変換テーブルを要求し、モジュール・サイズは劇的に増大されます。その結果、それらのコード・ページにおいてLFNを有効にしたFatFsモジュールは、AVRを含む殆どの8ビット・マイコンにインプリメントされることができません。

-

LFN機能のハードルはそれだけではありません。マイクロソフト社はFATファイル・システムについていくつかの特許を保有しています。いずれもLFN機能の実装に関するもので、その利用に対して$0.25/unitのライセンス料を要求しています。このため、商用製品でLFN機能を利用するときは、最終仕向地によってはライセンスが必要になります。最近のFAT32ドライバの多くはLFN機能を含んでいるため、それらの使用に当たってライセンスが必要になりますが、FatFsではLFN機能を構成オプションで任意にON/OFFできるため、無効にしてライセンス問題を回避することもできます。

-
- -
-

日本語ファイル名の大文字変換

-

CP932(Shift_JIS)でかつ非LFN構成のときは、拡張文字の小文字(2バイト英字・キリル文字・ギリシャ文字)に対して大文字変換を行わず、小文字のままSFNエントリに記録・検索されます(日本語MSDOS仕様)。このため、非LFN構成で全角小文字を含むファイルを作成すると、NT系Windowsでそのファイルを開けなくなります。LFN構成では大文字変換を行います(NT系Windows仕様)。

-
- -
-

Unicode入出力への対応

-

FatFs API上におけるファイル名等の文字列データの入出力は、デフォルトではANSI/OEMコードで行われますが、これをUnicode(UTF-16)に切り替えることもできます(_LFN_UNICODEオプションで設定)。つまり、これはFatFsがLFN機能に完全対応していることを意味します。Unicodeのファイル名に関する詳細は、ファイル名を参照してください。

-
- -
-

リエントランシー

-

互いに異なるボリュームに対するファイル操作はリエントラントで、常に同時平行に動作できます。同じボリュームに対してはデフォルトではリエントラントではありませんが、_FS_REENTRANTオプションでリエントラント(スレッド・セーフ)にすることはできます。この場合、OS依存の同期オブジェクト操作関数ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant(), ff_rel_grant()もまたプロジェクトに追加されなければなりません。サンプル・コードと解説はoption/syncobj.cにあります。

-

この場合、あるタスクがボリュームを使用中に他のタスクからそのボリュームに対するファイル関数が呼び出されると、そのアクセスは先のタスクがファイル関数を抜けるまでブロックされます。もし、待ち時間が_TIMEOUTで指定された期間を越すと、その関数はFR_TIMEOUTでアボートします。いくつかのRTOSではタイムアウト機能はサポートされないかも知れません。

-

ひとつの例外がf_mount(), f_mkfs(), f_fdisk()にあります。これらの関数は同じボリューム(または関連する物理ドライブ)に対してリエントラントではありません。これらの関数を使用するときは、アプリケーション・レベルで排他制御しなければなりません。

-

注: このセクションはFatFsモジュールそれ自体のリエントランシーについて説明しています。その下位のディスクI/Oモジュールのリエントランシーに関しては何の前提もありません。

-
- -
-

多重ファイル・アクセス

-

FatFsモジュールではデフォルトでは多重アクセス制御機能をサポートしていません。ファイルに対する多重アクセスは、そのアクセス・モードによって制限されます。一つのファイルに対する多重オープンは、それらが全てリード・モードのときに限って許可されます。書き込みモードを含む多重オープン、また開かれているファイルに対するリネームや削除を行ってはなりません。さもないと、そのボリュームのFAT構造が破壊される可能性があります。

-

_FS_LOCKに1以上の値(値は同時に管理できるファイル数)をセットすることで多重アクセス制御機能が有効になり、ファイル単位のアクセス制御を自動で行うこともできます。この場合、上記のルールを破ったオープン・リネーム・削除を試みると、その関数はFR_LOCKEDで失敗します。また、_FS_LOCKを越える数のファイルやサブ・ディレクトリを同時にオープンしようとすると、FR_TOO_MANY_OPEN_FILESで失敗します。

-
- -
-

効率的なファイル・アクセス

-

小規模な組込システムでのファイルの読み書きにおける効率の良いアクセスのため、アプリケーション・プログラマはFatFsモジュールの中でどのような処理が行われているか考慮すべきです。ストレージ上のデータはf_read()により次のシーケンスで転送されます。

-

図1. セクタ・ミスアラインド・リード (ショート)
-fig.1 -

-

図2. セクタ・ミスアラインド・リード (ロング)
-fig.2 -

-

図3. セクタ・アラインド・リード
-fig.3 -

-

ファイルI/Oバッファはセクタの一部のデータを読み書きするためのセクタ・バッファを意味します。セクタ・バッファは、それぞれのファイル・オブジェクト内のプライベート・セクタ・バッファまたはファイル・システム・オブジェクト内の共有セクタ・バッファのどちらかです。バッファ構成オプションの_FS_TINYは、データ転送にどちらを使うかを決定します。タイニー・バッファ(1)が選択されるとデータ・メモリの消費はそれぞれのファイル・オブジェクトで512バイト減少されます。この場合、FatFsモジュールはファイル・データの転送とFAT/ディレクトリ・アクセスにファイル・システム・オブジェクト内のセクタ・バッファだけを使用します。タイニー・バッファの欠点は、セクタ・バッファにキャッシュされたFATデータがファイル・データの転送により失われ、クラスタ境界の毎にリロードされなければならないことです。でも、悪くない性能と少ないメモリ消費の視点から多くのアプリケーションに適するでしょう。

-

図1はセクタの一部のデータがファイルI/Oバッファを経由で転送されることを示します。図2に示される長いデータの転送では、転送データの中間の1セクタまたはそれ以上のセクタにまたがる転送データがアプリケーション・バッファに直接転送されています。図3は転送データ全体がセクタ境界にアライメントされている場合を示しています。この場合、ファイルI/Oバッファは使用されません。直接転送においては最大の範囲のセクタがdisk_read()で一度に読み込まれますが、クラスタ境界を越えるマルチ・セクタ転送はそれが隣接であっても行われません。

-

このように、セクタにアライメントしたファイルの読み書きへの配慮はバッファ経由のデータ転送を避け、読み書き性能は改善されるでしょう。その効果に加え、タイニー構成でキャッシュされたFATデータがファイル・データの転送によりフラッシュされず、非タイニー構成と同じ性能を小さなメモリ・フットプリントで達成できます。

-
- -
-

フラッシュ・メモリの特性への配慮

-

HDDなどのディスク・メディアとは異なり、SDCやCFCなどのフラッシュ・メモリ・メディアの性能を引き出すには、その特性を意識した制御が必要になります。

-

マルチ・セクタ書き込み

-
-図6. マルチ/シングル・セクタ・ライトの比較
-fig.6 -
-

フラッシュ・メモリ・メディアの書き込み速度はシングル・セクタ書き込みの時に最も低いものになり、一回のトランザクションで転送されるセクタ数が大きくなるほど書き込み速度は向上します。この効果はバス速度が高速になるほど顕著で、10倍以上の差が現れることも珍しくありません。テスト結果は、マルチ・セクタ書き込み(W:16K, 32 sectors)がシングル・セクタ書き込み(W:100, 1 sector)がどの程度速いかを明確に示しています。大容量メディアほどシングル・セクタ書き込みが遅くなる点もまた重要です。書き込みトランザクションの回数はまた、メディアの寿命にも影響してきます。このため、アプリケーションはなるべく大きなブロック(クラスタ・サイズまたは2の累乗セクタ境界にアライメントした)で読み書きを行う必要があります。もちろん、アプリケーションからメディアに至る全てのレイヤがマルチ・セクタ転送に対応していないと意味がありません。残念ながら、既存のオープン・ソースのドライバの多くはマルチ・セクタ転送に未対応です。なお、FatFsモジュールおよびサンプル・ドライバはマルチ・セクタ転送に対応しています。

-

明示的なメモリ消去

-

通常のファイル消去では、記録されたデータに対して何らかの制御が行われるわけではなく、単にFAT上に未使用クラスタとして記録されているだけです。このため、ファイルが消去されたあともそれらは有効なメモリ・ブロックとしてフラッシュ・メモリ上に残ります。そこで、ファイルを消去するとき、占有していたデータ・セクタを明示的に消去(つまり未使用ブロックにする)することにより、メディア内の空きブロックを増やすことができます。これにより、次にそのブロックに書き込むときの消去動作が無くなり、書き込み性能が向上する可能性があります。また、ウェアレベリングに使えるブロックが増え、メディアの耐久性も向上するかも知れません。この機能を有効にするには、構成オプションの_USE_ERASEに1を設定します。これはフラッシュ・メモリ・メディアの内部動作に期待した制御なので、効果があるとは限りません。また、ファイル消去の時間が延びることも考慮に入れるべきです。

-
- -
-

クリチカル・セクション

-

ストレージ上のFAT構造を操作している途中で、停電、不正なメディアの取り外し、回復不能なデータ・エラー等の障害が発生すると、処理が中途半端な状態で中断され、その結果としてFATボリュームの構造が破壊される可能性があります。次にFatFsモジュールにおけるクリチカル・セクションと、その間の障害により起きうるエラーの状態を示します。

-
-図4. 長いクリチカル・セクション
-fig.4 -
-
-図5. 最小化したクリチカル・セクション
-fig.5 -
-
-

赤で示したセクションを実行中に障害が発生した場合、クロス・リンクが発生して操作対象のファイル・ディレクトリが失われる可能性があります。黄色で示したセクションを実行中に障害が発生した場合、つぎのうちいずれかまたは複数の結果が生じる可能性があります。

-
    -
  • 書き換え中のファイルのデータが破壊される。
    • -
  • 追記中のファイルがオープン前の状態に戻る。
    • -
  • 新規に作成されたファイルが消える。
    • -
  • 新規または上書きで作成されたファイルの長さがゼロになって残る。
    • -
  • ロストチェーンの発生によりボリュームの利用効率が悪化する。
    • -
-

いずれも書き込み中や操作の対象でないファイルには影響はありません。これらのクリチカル・セクションは、ファイルを書き込みモードで開いている時間を最小限にするか、f_sync()を適宜使用することで図5のようにリスクを最小化することができます。

FatFsのライセンスについて

-

ソース・ファイルのヘッダにライセンス条件が記述されているので、利用の際はそれに従うこと。英語を読めない方のために以下に日本語訳を示しておきます。

-
/*----------------------------------------------------------------------------/

ポーティングの際に配慮すべきこと

+ +

移植の際の前提条件

+

FatFsモジュールは移植性に関して次の点を前提としています。

+
    +
  • 処理系はANSI C準拠であること。
    +FatFsモジュールはANSI C(C89)準拠で記述されているので、普通のCコンパイラなら特に処理系依存になる点はありません。
    • +
  • char/short/longのサイズは、それぞれ8/16/32ビットで、intは16または32ビットであること。
    +これについても、まっとうな処理系なら問題ないはずです。FatFsモジュールで使用されるサイズを明示する整数型が integer.h 内で定義されていますが、既存の定義と衝突した場合はユーザによって解決されなければなりません。
    • +
+ +

システム構成

+

下に示す依存関係図は、FatFsモジュール利用の組み込みシステムにおける代表的な構成を示します。

+

システム構成図

+

(a) FatFs用に書かれたディスク・モジュールがある場合は、そのまま追加するだけです。 (b) しかし、多くの既存のディスク・モジュールはそのAPIをFatFsに合わせるため、グルー関数が必要になるでしょう。

+

functional diagram

+ +

ユーザの作成する関数

+

必要なのはFatFsモジュールの要求するディスク関数を用意することだけで、それ以外にすることはありません。既に動作しているディスク・モジュールがあるなら、そのAPIをFatFsに合わせるかグルー関数を介してつなぐだけで済みますが、無い場合はほかから移植するか最初から書くかする必要があります。定義されている全ての関数が常に必要なわけではありません。例えば、リード・オンリー構成では書き込み系関数は必要ありません。次の表に構成オプションと要求される関数の対応を示します。

長いファイル名

+

FatFsモジュールは、長いファイル名(LFN)をサポートします。ファイルに付けられた2つの異なる名前(短いファル名と長いファイル名)は、f_readdir()を除くファイル操作関数において透過です。デフォルト構成では、LFN機能はOFFになっています。LFN機能を有効にするには、_USE_LFNを1,2または3に設定し、option/unicode.cをプロジェクトに追加します。LFN機能は、加えてある程度のワーク・エリア(LFN操作バッファ)を必要とします。バッファ長は使用できるメモリに応じて_MAX_LFNオプションで構成されることができます。LFNの長さは最大255文字に達するので、LFN完全対応のためには_MAX_LFNは255に設定されるべきです。与えられたファイル名に対してバッファ長が不足した場合、ファイル関数はFR_INVALID_NAMEで失敗します。

+

ファイル関数に再入を行う条件の下でLFN機能を使用する場合は、_USE_LFNは2または3に設定されなければなりません。この場合、ファイル関数はワーク・エリアを動的に確保(スタックまたはヒープ)します。バッファ・サイズは、(_MAX_LFN + 1) * 2バイトになるので、スタック等のサイズはそれを考慮した十分なサイズでなければなりません。

+ + + + + + + + +
LFN cfg on ARM7
コードページコードサイズ[bytes]
SBCS+3721
932(Shift-JIS)+62609
936(GBK)+177797
949(Korean)+139857
950(Big5)+111497
+

LFN機能の上手な使い方は、それを使わないということです。実際、組み込み用途ではLFN機能がどうしても必要になるということはほとんど無いはずです。LFNを有効にすると、選択されたコード・ページに応じてモジュール・サイズが増大されます。右の表に各コード・ページにおけるLFNを有効にしたときのモジュール・サイズの違いを示します。特に、CJK地域では数万の文字が使われていますが、不幸なことにそれは巨大なOEM－Unicode相互変換テーブルを要求し、モジュール・サイズは劇的に増大されます。その結果、それらのコード・ページにおいてLFNを有効にしたFatFsモジュールは、AVRを含む殆どの8ビット・マイコンにインプリメントされることができません。

+

LFN機能のハードルはそれだけではありません。マイクロソフト社はFATファイル・システムについていくつかの特許を保有しています。いずれもLFN機能の実装に関するもので、その利用に対して$0.25/unitのライセンス料を要求しています。このため、商用製品でLFN機能を利用するときは、最終仕向地によってはライセンスが必要になります。最近のFAT32ドライバの多くはLFN機能を含んでいるため、それらの使用に当たってライセンスが必要になりますが、FatFsではLFN機能を構成オプションで任意にON/OFFできるため、無効にしてライセンス問題を回避することもできます。

+
+ +
+

日本語ファイル名の大文字変換

+

CP932(Shift_JIS)でかつ非LFN構成のときは、拡張文字の小文字(2バイト英字・キリル文字・ギリシャ文字)に対して大文字変換を行わず、小文字のままSFNエントリに記録・検索されます(日本語MSDOS仕様)。このため、非LFN構成で全角小文字を含むファイルを作成すると、NT系Windowsでそのファイルを開けなくなります。LFN構成では大文字変換を行います(NT系Windows仕様)。

+
+ +
+

Unicode入出力への対応

+

FatFs API上におけるファイル名等の文字列データの入出力は、デフォルトではANSI/OEMコードで行われますが、これをUnicode(UTF-16)に切り替えることもできます(_LFN_UNICODEオプションで設定)。つまり、これはFatFsがLFN機能に完全対応していることを意味します。Unicodeのファイル名に関する詳細は、ファイル名を参照してください。

+
+ +
+

リエントランシー

+

互いに異なるボリュームに対するファイル操作はリエントラントで、常に同時平行に動作できます。同じボリュームに対してはデフォルトではリエントラントではありませんが、_FS_REENTRANTオプションでリエントラント(スレッド・セーフ)にすることはできます。この場合、OS依存の同期オブジェクト操作関数ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant(), ff_rel_grant()もまたプロジェクトに追加されなければなりません。サンプル・コードと解説はoption/syncobj.cにあります。

+

この場合、あるタスクがボリュームを使用中に他のタスクからそのボリュームに対するファイル関数が呼び出されると、そのアクセスは先のタスクがファイル関数を抜けるまでブロックされます。もし、待ち時間が_TIMEOUTで指定された期間を越すと、その関数はFR_TIMEOUTでアボートします。いくつかのRTOSではタイムアウト機能はサポートされないかも知れません。

+

ひとつの例外がf_mount(), f_mkfs(), f_fdisk()にあります。これらの関数は同じボリューム(または関連する物理ドライブ)に対してリエントラントではありません。これらの関数を使用するときは、アプリケーション・レベルで排他制御しなければなりません。

+

注: このセクションはFatFsモジュールそれ自体のリエントランシーについて説明しています。その下位のディスクI/Oモジュールのリエントランシーに関しては何の前提もありません。

+
+ +
+

多重ファイル・アクセス

+

FatFsモジュールではデフォルトでは多重アクセス制御機能をサポートしていません。ファイルに対する多重アクセスは、そのアクセス・モードによって制限されます。一つのファイルに対する多重オープンは、それらが全てリード・モードのときに限って許可されます。書き込みモードを含む多重オープン、また開かれているファイルに対するリネームや削除を行ってはなりません。さもないと、そのボリュームのFAT構造が破壊される可能性があります。

+

_FS_LOCKに1以上の値(値は同時に管理できるファイル数)をセットすることで多重アクセス制御機能が有効になり、ファイル単位のアクセス制御を自動で行うこともできます。この場合、上記のルールを破ったオープン・リネーム・削除を試みると、その関数はFR_LOCKEDで失敗します。また、_FS_LOCKを越える数のファイルやサブ・ディレクトリを同時にオープンしようとすると、FR_TOO_MANY_OPEN_FILESで失敗します。

+
+ +
+

効率的なファイル・アクセス

+

小規模な組込システムでのファイルの読み書きにおける効率の良いアクセスのため、アプリケーション・プログラマはFatFsモジュールの中でどのような処理が行われているか考慮すべきです。ストレージ上のデータはf_read()により次のシーケンスで転送されます。

+

図1. セクタ・ミスアラインド・リード (ショート)
+fig.1 +

+

図2. セクタ・ミスアラインド・リード (ロング)
+fig.2 +

+

図3. セクタ・アラインド・リード
+fig.3 +

+

ファイルI/Oバッファはセクタの一部のデータを読み書きするためのセクタ・バッファを意味します。セクタ・バッファは、それぞれのファイル・オブジェクト内のプライベート・セクタ・バッファまたはファイル・システム・オブジェクト内の共有セクタ・バッファのどちらかです。バッファ構成オプションの_FS_TINYは、データ転送にどちらを使うかを決定します。タイニー・バッファ(1)が選択されるとデータ・メモリの消費はそれぞれのファイル・オブジェクトで512バイト減少されます。この場合、FatFsモジュールはファイル・データの転送とFAT/ディレクトリ・アクセスにファイル・システム・オブジェクト内のセクタ・バッファだけを使用します。タイニー・バッファの欠点は、セクタ・バッファにキャッシュされたFATデータがファイル・データの転送により失われ、クラスタ境界の毎にリロードされなければならないことです。でも、悪くない性能と少ないメモリ消費の視点から多くのアプリケーションに適するでしょう。

+

図1はセクタの一部のデータがファイルI/Oバッファを経由で転送されることを示します。図2に示される長いデータの転送では、転送データの中間の1セクタまたはそれ以上のセクタにまたがる転送データがアプリケーション・バッファに直接転送されています。図3は転送データ全体がセクタ境界にアライメントされている場合を示しています。この場合、ファイルI/Oバッファは使用されません。直接転送においては最大の範囲のセクタがdisk_read()で一度に読み込まれますが、クラスタ境界を越えるマルチ・セクタ転送はそれが隣接であっても行われません。

+

このように、セクタにアライメントしたファイルの読み書きへの配慮はバッファ経由のデータ転送を避け、読み書き性能は改善されるでしょう。その効果に加え、タイニー構成でキャッシュされたFATデータがファイル・データの転送によりフラッシュされず、非タイニー構成と同じ性能を小さなメモリ・フットプリントで達成できます。

+
+ +
+

フラッシュ・メモリの特性への配慮

+

HDDなどのディスク・メディアとは異なり、SDCやCFCなどのフラッシュ・メモリ・メディアの性能を引き出すには、その特性を意識した制御が必要になります。

+

マルチ・セクタ書き込み

+
+図6. マルチ/シングル・セクタ・ライトの比較
+fig.6 +
+

フラッシュ・メモリ・メディアの書き込み速度はシングル・セクタ書き込みの時に最も低いものになり、一回のトランザクションで転送されるセクタ数が大きくなるほど書き込み速度は向上します。この効果はバス速度が高速になるほど顕著で、10倍以上の差が現れることも珍しくありません。テスト結果は、マルチ・セクタ書き込み(W:16K, 32 sectors)がシングル・セクタ書き込み(W:100, 1 sector)よりどの程度速いかを明確に示しています。大容量メディアほどシングル・セクタ書き込みが遅くなる点もまた重要です。書き込みトランザクションの回数はまた、メディアの寿命にも影響してきます。このため、アプリケーションはなるべく大きなブロック(クラスタ・サイズまたは2の累乗セクタ境界にアライメントした)で読み書きを行う必要があります。もちろん、アプリケーションからメディアに至る全てのレイヤがマルチ・セクタ転送に対応していないと意味がありません。残念ながら、既存のオープン・ソースのドライバの多くはマルチ・セクタ転送に未対応です。なお、FatFsモジュールおよびサンプル・ドライバはマルチ・セクタ転送に対応しています。

+

明示的なメモリ消去

+

通常のファイル消去では、記録されたデータに対して何らかの制御が行われるわけではなく、単にFAT上に未使用クラスタとして記録されているだけです。このため、ファイルが消去されたあともそれらは有効なメモリ・ブロックとしてフラッシュ・メモリ上に残ります。そこで、ファイルを消去するとき、占有していたデータ・セクタを明示的に消去(つまり未使用ブロックにする)することにより、メディア内の空きブロックを増やすことができます。これにより、次にそのブロックに書き込むときの消去動作が無くなり、書き込み性能が向上する可能性があります。また、ウェアレベリングに使えるブロックが増え、メディアの耐久性も向上するかも知れません。この機能を有効にするには、構成オプションの_USE_ERASEに1を設定します。これはフラッシュ・メモリ・メディアの内部動作に期待した制御なので、効果があるとは限りません。また、ファイル消去の時間が延びることも考慮に入れるべきです。

+
+ +
+

クリチカル・セクション

+

ストレージ上のFAT構造を操作している途中で、停電、不正なメディアの取り外し、回復不能なデータ・エラー等の障害が発生すると、処理が中途半端な状態で中断され、その結果としてFATボリュームの構造が破壊される可能性があります。次にFatFsモジュールにおけるクリチカル・セクションと、その間の障害により起きうるエラーの状態を示します。

+
+図4. 長いクリチカル・セクション
+fig.4 +
+
+図5. 最小化したクリチカル・セクション
+fig.5 +
+
+

赤で示したセクションを実行中に障害が発生した場合、クロス・リンクが発生して操作対象のファイル・ディレクトリが失われる可能性があります。黄色で示したセクションを実行中に障害が発生した場合、つぎのうちいずれかまたは複数の結果が生じる可能性があります。

+
    +
  • 書き換え中のファイルのデータが破壊される。
    • +
  • 追記中のファイルがオープン前の状態に戻る。
    • +
  • 新規に作成されたファイルが消える。
    • +
  • 新規または上書きで作成されたファイルの長さがゼロになって残る。
    • +
  • ロストチェーンの発生によりボリュームの利用効率が悪化する。
    • +
+

いずれも書き込み中や操作の対象でないファイルには影響はありません。これらのクリチカル・セクションは、ファイルを書き込みモードで開いている時間を最小限にするか、f_sync()を適宜使用することで図5のようにリスクを最小化することができます。

+
+ +

FatFsのライセンスについて

+

ソース・ファイルのヘッダにライセンス条件が記述されているので、利用の際はそれに従うこと。英語を読めない方のために以下に日本語訳を示しておきます。

+
/*----------------------------------------------------------------------------/
+/  FatFs - FAT file system module  R0.10b                   (C)ChaN, 2014
+/-----------------------------------------------------------------------------/

+/   ものから商用製品の開発に及ぶ目的に使用・改変・再配布することができます。
+/ * ソース・コードを再配布するときは、上記の著作権表示を保持しなければなりません。
+/
+/-----------------------------------------------------------------------------/
+

要するにFatFsはタダで自由に使えるということです。ソース・コードを再配布するときは、このブロックをそのまま保持しておくこと。このようにFatFsはBSDライクなライセンスとしていますが、一つ大きな違いがあります。特に組み込み用途での利用価値を高めるため、バイナリ形式(ソース・コードを含まない形式全て)での再配布については、条件は設けていません。その場合は、FatFsおよびそのライセンス文書についてはドキュメントに明記してもしなくてもかまいません。これは、一条項BSDライセンスと等価ということです。もちろんGNU GPLプロジェクトとも共存可能です。何らかの変更を加えて再配布する際は、矛盾しない他のライセンス(GNU GPLや修正BSDライセンスなど)に変更することも可能です。

パス名のフォーマット

-
-

ファイル・ディレクトリ名

-

FatFsモジュールでのファイル、ディレクトリ、ドライブの指定方法はDOS/Windows APIとほぼ同じです。パス名のフォーマットは次の通りです。

-
"[論理ドライブ番号:][/]ディレクトリ名/ファイル名"
-

FatFsモジュールは長いファイル名(LFN)および8.3形式ファイル名(SFN)に対応しています。LFNは、(_USE_LFN > 0)のとき使用可能になります。ディレクトリ・セパレータにはDOS/Windows APIと同じく'/'と'\'を使用します。連続したセパレータは無視され1個として扱われます。唯一の違いは、論理ドライブの指定だけです。論理ドライブ番号は、'0'～'9'の一文字の数字とコロンで指定し、省略した場合はデフォルト・ドライブ(0またはカレント・ドライブ)が選択されます。

-

ヌル文字や制御文字('\0'～'\x1F')は、パス名の終端として認識されます。パス名に先行あるいは中に含まれるスペースは、LFN構成では名前の一部として有効ですが、非LFN構成ではスペースはパス名の終端として認識されます。

-

標準構成(_FS_RPATH == 0)のときは、全てのオブジェクトがルート・ディレクトリから辿る絶対パスで指定されます。OS指向なカレント・ディレクトリという概念は無く、またドット・ディレクトリ("."や"..")は使用できません。パス名先頭のセパレータは無視されます。デフォルト・ドライブ番号は常に0になります。

-

相対パスを有効(_FS_RPATH == 1)にしたときは、先行するセパレータの有無によって検索開始ディレクトリが変わり、セパレータがある場合はルート・ディレクトリから、無い場合はf_chdir()で設定されるカレント・ディレクトリからになります。またパス名にドット・ディレクトリが使用できます。デフォルト・ドライブ番号はf_chdrive()で設定された値となります。

Unicode API

-

ファイル関数の入出力のうちファイル名やパス名を指定する引数の型は、TCHARで定義されていますが、これは通常はcharのエリアスになっています。そして、_CODE_PAGEで指定されるANSI/OEMコード(SBCSまたはDBCS)の文字列として扱われます。ファイル名入出力をUnicodeとする構成(_LFN_UNICODE == 1)にしたときは、TCHARはワイド文字(WCHAR, unsigned short)に切り替わり、パス名の入出力にUnicodeを使用するようになります。これによりLFN規格に完全対応となり、ANSI/OEMコードにない文字(たとえば ✝☪✡☸☭など)も使用できます。この設定は文字列入出力関数のデータ型とファイル上のエンコーディングにも影響を与えます。リテラル文字列を定義するとき、次に示すように_T(s)および_TEXT(s)マクロを使ってANSI/OEMとUnicodeを自動切り替えすることができます。

-
- f_open(fp, "filename.txt", FA_READ);      /* ANSI/OEM専用コード */
- f_open(fp, L"filename.txt", FA_READ);     /* Unicode専用コード */
- f_open(fp, _T("filename.txt"), FA_READ);  /* 両用コード(自動切り替え) */

ボリューム管理

デフォルトの構成では、それぞれの論理ドライブは同じ番号の物理ドライブに1:1で結びつけられていて、自動検出機能によりその物理ドライブ上の一つのFATボリュームがマウントされます。FATボリュームの検出は、セクタ0、第一区画～第四区画の順に行われます。

-

_MULTI_PARTITIONに1を指定すると、それぞれの論理ドライブに対して個別に物理ドライブ番号と区画を指定できるようになります。この構成では、論理ドライブと区画の対応を解決するためのテーブルを次に示すように定義する必要があります。

-
-例:論理ドライブ0～2を物理ドライブ0(非リムーバブル)の3つの基本区画に割り当て、
-   論理ドライブ3を物理ドライブ1(リムーバブル)に割り当てる場合。

-    {0, 3},     /* 論理ドライブ 2 ==> 物理ドライブ 0, 第3区画 */
-    {1, 0}      /* 論理ドライブ 3 ==> 物理ドライブ 1, 自動検出 */
-};

複数区画指定を使用する場合、次の点に注意しなければなりません。 -

    -
  • マウント可能な区画は基本区画のみで、拡張区画内には対応しない。
    • -
  • 複数のマウントされた区画を持つ物理ドライブは、非リムーバブルでなければならず、システム動作中のメディア交換は禁止。

ファイル関数の戻り値

+

FatFsのAPIでは、一部の関数を除き結果に応じた共通のリザルト・コード(FRESULT型(enum))を返します。関数が成功した場合は0を返します。失敗した場合は0以外の値を返し、値はエラーの種類を示します。

+ +
+
FR_OK (0)
+
関数は成功した。
+
FR_DISK_ERR
+
下位レイヤ(disk_read(), disk_write(), disk_ioctl()関数)で回復不能なエラーが発生した。
※開かれたファイルの操作においてこのエラーが発生すると、そのファイル・オブジェクトはアボート状態となり、クローズ以外のの操作ができなくなります。
+
FR_INT_ERR
+
内部処理の健全性に異常が検出された。原因としては次のようなことが考えられます。 +
    +
  • ボリューム上のFAT構造にエラーがある。
    • +
  • スタック不足や不正なメモリ操作等によるワーク・エリアの破壊。多くはこれが原因。
    • +
+※開かれたファイルの操作においてこのエラーが発生すると、そのファイル・オブジェクトはアボート状態となり、クローズ以外の操作ができなくなります。
+
FR_NOT_READY
+
物理ドライブが動作可能な状態にない。または、ドライブの初期化に失敗した。
