Compressed ramdisk found but not mounted

Hello everyone,

I am working on a fads 823 board. I am trying to boot the kernel and mount
the ramdisk file system from flash. The kernel boots up just fine and also
finds the compressed ramdisk image... But nothing happens after that. It
does not mount the file system. I have all the kernel configurations set and
I have the /dev/ram device which actually points to /dev/ram1 in the
filesystem. What else could go wrong? Can someone please help?

Thank you,
