no, you should use initramfs and don't specify kernel command string.

the problem maybe you miss the rootfs.

did you follow the uclinux-dist wiki page?

http://nioswiki.jot.com/wikihome/operating...nux/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist)

check if files exist in uclinux-dist/romfs.

and run "make" and "make linux image" again.
