fs: implement size/fatsize/ext4size

2014-08-09T15:16:57+00:00

These commands may be used to determine the size of a file without
actually reading the whole file content into memory. This may be used
to determine if the file will fit into the memory buffer that will
contain it. In particular, the DFU code will use it for this purpose
in the next commit.

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.
