yes,the next step is build a rw filesystem,that's very annoying http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

To successfully build an rw filesystem copy the filesystem files on Compact Flash previously partitioned with an ext2fs on hda1, try mknod for all device in /dev directory, then specify the root=0301 in kernel config, recompile the kernel and upload it.

Good Luck
