You have to provide a working root filesystem in the first place.

This is normal. If you use U-boot there is no need to have any
pre-compiled boot arguments; more: there is no need to use the whole
bootstrap loader which supplied these precompiled bootargs.

Just define the required bootargs in U-Boot.

Do not ignore this error. How big is your cramfs iage? How much RAM
do you have?

Is there any chance that you built your cramfs image on a x08 (or any
other little-endian) system and forgot to give the "-r" (reverse
endian-ness of filesystem) option to mkcramfs??
