    Long File Name

    -

    The FatFs module has started to support long file name (LFN) at revision 0.07. The two different file names, SFN and LFN, of a file is transparent in the file functions except for f_readdir function. To enable LFN feature, set _USE_LFN to 1, 2 or 3, and add a Unicode code conversion function ff_convert() and ff_wtoupper() to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by _MAX_LFN corresponding 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 feature, _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.

This is the reason why I had not been interested in implementing the LFN feature for a long time :-)

    Duplicated File Access

    FatFs module does not support the shareing controls of duplicated file access in default. It is permitted when open method to a file is only read mode. The duplicated open in write mode to a file is always prohibited and open file must not be renamed, deleted, or the FAT structure on the volume can be collapted.

    The file shareing control can also be available when _FS_LOCK is set to 1 or grater. The value specifies the number of files 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 gets larger than _FS_LOCK, the f_open function will fail with FR_TOO_MANY_OPEN_FILES.

    Figure 3. Sector aligned read

    The file I/O buffer means 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 on 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 on 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 partial sector data is transferred via the file I/O buffer. On long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to 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 multi sector transfer never across the cluster boundary even if it is contiguous.

    Therefore taking effort to sector aligned read/write accesss avoids buffered data transfer and the read/write performance will be improved.

    @@ -202,12 +208,12 @@ Figure 6. Comparison between Multiple/Single Sector Write

    The write throughput of the flash memory media becomes the worst at single sector write and it increases proportional to the number of sectors per a write transaction. This effect more appers at more fast bus clock and its ratio often becomes grater than ten. The number of write transaction also affects the life time of the media. Therefore the application program should write the data in large block as possible. The ideal block size is cluster size or power of 2 bytes and the byte offset should be aligned to the block. Of course all layers between the application and the media must support multiple sector write feature, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector writes 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 blocks. If the file data is forced erased on removing the file, the number of free blocks on the flash memory will be increased. This may skip internal block erase operation to the data block on next write. As the result the write performance might be improved. To enable this feature, set _USE_ERASE to 1. Note that this is a feature with expectation of internal process of the flash memory media. It may not always effective and f_remove function will take a time on removing a large file.

    CommandDescription
    CTRL_SYNCMake sure that the disk drive has finished pending write process. When the disk I/O module has a write back cache, flush the dirty sector immediately. This command is not used in read-only configuration.
    GET_SECTOR_SIZEReturns sector size of the drive into the WORD variable pointed by Buffer. This command is not used in fixed sector size configuration, _MAX_SS is 512.
    GET_SECTOR_COUNTReturns number of available sectors on the drive into the DWORD variable pointed by Buffer. This command is used by only f_mkfs function to determine the volume size to be created.
    GET_BLOCK_SIZEReturns erase block size of the flash memory in unit of sector into the DWORD variable pointed by Buffer. The allowable value is 1 to 32768 in power of 2. Return 1 if the erase block size is unknown or disk devices. This command is used by only f_mkfs function and it attempts to align data area to the erase block boundary.
    CTRL_ERASE_SECTORErases a part of the flash memory specified by a DWORD array {<start sector>, <end sector>} pointed by Buffer. When this feature is not supported or not a flash memory media, this command has no effect. The FatFs does not check the result code and the file function is not affected even if the sectors are not erased well. This command is called on removing a cluster chain when _USE_ERASE is 1.

      Note that there are two partitioning rules, FDISK and SFD. The FDISK partitioning is usually used for harddisk, MMC, SDC and CFC. 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 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.

    GET_SECTOR_COUNTBufferの指すDWORD変数にドライブ上の総セクタ数を返します。f_mkfs関数内で作成するボリュームのサイズを決定するために使用されます。
    GET_BLOCK_SIZEフラッシュ・メモリの消去ブロック・サイズをBufferの指すDWORD変数にセクタ単位で返します。1から32768でかつ2の累乗の値でなければなりません。不明な場合またはフラッシュ・メモリ以外のメディアでは1を返します。f_mkfs関数内でのみ使用され、ボリュームのデータ領域はこの境界にアライメントされます。
    CTRL_ERASE_SECTORフラッシュ・メモリの一部の領域を消去します。Bufferの指すDWORD配列には消去する領域 {開始セクタ,終了セクタ} を指定して呼び出します。この機能をサポートしない場合やフラッシュ・メモリ以外のメディアでは何もしません。この機能の戻り値はチェックされず、また、指定領域の消去が完全に行われなかったとしてもファイル・システムの動作には影響ありません。_USE_ERASEが1のとき、クラスタが解放されるときに呼び出されます。
