Re: [Gumstix-users] Having trouble accessing CF card..

[Chris D. <chr...@gm...>]

Yeah, chown/chmod won't work with FAT. Have you tried passing a umask
option in your fstab? Googling 'linux fat mount permissions' seems to
bring back a number of posts that might hold the key to getting user
write access working. I haven't used fat filesystems with Linux in
quite some time myself.
