^^^^^^^^
This makes no sense. A cramfs image should go directly to flash, and be accessed through the Linux kernel's MTD layer. Treating it as a ramdisk is not a good idea.
However, the uClinux kernel cannot find the filesystem to mount.
Don't do this, then.
What is the correct mkimage parameters for cramfs.img ?
There is none. Only "initial ramdisks" are wrapped by mkimage; all other filesystem images go directly to flash. Use MTD to access these.
