Chris,
As far as I know, you have to use CRAMFS. Basically
what you're doing is taking the first 1MB of the chip
for the bootstrap & kernel and then formatting the
rest of the chip (2MB-8MB) as a file system.
I have not had a chance to use Ollie's File System,
but may get some time early this afternoon to see if
it works better than the one I built. I could get mine
to mount, but never could get a login. Check the
Archives for the specifics on my problems.
I think you'll also need to use RAMFS for /tmp. Which
is where I left off. I did not have any writable
storage and I think that's where I went wrong.
