The fat driver in uClinux is unchanged AFAICT from linux.

I run the current uClinux kernel on my desktop and my MP3 player hooks
up fine so I am fairly sure it works ok ;-).

If the fat code is not working for you then I would suspect the
platform differences first.  Big-endian/little endian ?  Interface
problems ?  It's hard to say really.

Are you using the VFAT driver or just the FAT driver ?

Are you mounting the correct device ?  If thereare partitions
you need to mount the partition (ie., /dev/sad1 for partition 1),

Cheers,
