hi slsnios,

there are many possible causes.

first, make sure you don't have the broken cramfs code. see:

http://forum.niosforum.com/forum/index.php...=2383&hl=cramfs (http://forum.niosforum.com/forum/index.php?showtopic=2383&hl=cramfs)

once you're sure your cramfs code is clean, you might want to enable jffs2/cramfs support in

u-boot. this will allow you to list and load jffs2/cramfs files into ram and view some file system

information -- it's a good way to ensure you have a clean filesystem image _before_ you boot

the kernel.

and, of course, double-check your kernel configuration to ensure you have cramfs support

enabled ;-)
