RE: [Fwd: Re: kernel command line for CRAMFS root filesystem]

Do not use
root=/dev/mtdblock/2
but
root=/dev/mtdblock2
even if you are using devfs

root=/dev/mdtblock/2 will be interpreted as root=/dev/mtdblock0

This is because of how the kernel parses the root argument on the command line.

Hope this helps,

K.D.

i have never mounted it before .

i am currently booting with initrd (good :-)) from my flash
and it works
fine( the commandline was : root=/dev/rd/0 );
but now i want to replace that with a cramfs (better :-)) .

anyway, i know i can acess to the range (start 0xfe100000 - length
2MBytes) via my partition /dev/mtdblock/2 but if i try
something like :
   root=/dev/mtdblock/2 then JFFS2 try to mount it as root
filesystem and
fails !!!!!!

maybe i should add something to the commandline, in order to tell the
kernel that /dev/mtdblock/2 contains a CRAMFS partition ??
