fat: Define MAX_CLUSTSIZE using CONFIG_FS_FAT_MAX_CLUSTSIZE

2014-06-05T18:44:56+00:00

Define the MAX_CLUSTSIZE to default of 65536 only if
CONFIG_FS_FAT_MAX_CLUSTSIZE is not defined.
This option has been provided to save memory in some
memory constrained cases.

fs: fat_write: fix the incorrect last cluster checking

2014-05-12T20:31:50+00:00

In fat_write.c, the last clust condition check is incorrect:

  if ((curclust >= 0xffffff8) || (curclust >= 0xfff8)) {
  	... ...
  }

For example, in FAT32 if curclust is 0x11000. It is a valid clust.
But on above condition check, it will be think as a last clust.

So the correct last clust check should be:
  in fat32, curclust >= 0xffffff8
  in fat16, curclust >= 0xfff8
  in fat12, curclust >= 0xff8

This patch correct the last clust check.

fat: implement exists() for FAT fs

2014-02-19T14:47:34+00:00

This hooks into the generic "file exists" support added in an earlier
patch, and provides an implementation for the FAT filesystem.

fs: Move ls and read methods into ext4, fat

2013-03-04T19:19:56+00:00

It doesn't make a lot of sense to have these methods in fs.c. They are
filesystem-specific, not generic code. Add each to the relevant
filesystem and remove the associated #ifdefs in fs.c.

FAT: implement fat_set_blk_dev(), convert cmd_fat.c

2012-10-25T19:07:47+00:00

This makes the FAT filesystem API more consistent with other block-based
filesystems. If in the future standard multi-filesystem commands such as
"ls" or "load" are implemented, having FAT work the same way as other
filesystems will be necessary.

Convert cmd_fat.c to the new API, so the code looks more like other files
implementing the same commands for other filesystems.

FAT: Make it possible to read from any file position

2012-09-26T18:11:32+00:00

When storage devices contain files larger than the embedded RAM, it is
useful to be able to read these files by chunks, e.g. for a software
update to the embedded NAND Flash from an external storage device (USB
stick, SD card, etc.).

Hence, this patch makes it possible by adding a new FAT API to read
files from a given position. This patch also adds this feature to the
fatload command.

fat: fix FAT sector offsets overflow on large FAT partitions

2012-05-22T08:14:05+00:00

This patch fixes several issues where sector offsets can overflow due
to being limited to 16-bits. The cases where an overflow can happen
when accessing large FAT32 partitions are:

 - length of FAT in sectors
 - start sector of root directory
 - the sector of the first cluster

These issues were observed when reading files from a 64GB FAT32
filesystem.
