Summary: excution of "ls" command in vfat fs in BF548 harddisk will fail when vfat partition is large

Details:

In 08r1 bf548, mount a vfat filesystem in hard disk and copy file into it, excution of "ls" command in vfat filesystem will fail.

Sometimes no files will be listed, sometimes "ls" lead to crash.

If the vfat partition is not greater than 2GB, it's ok.

--- Sonic Zhang 2008-03-11 00:05:20

When partition size is larger than 2G, you should format it with following

command.

root:/> mkdosfs -F 32 /dev/sda1

--- Vivi Li 2008-03-12 03:41:21

It's OK when add option "-F 32". Close it. Thanks!
