It looks like you have not loaded a kernel, you have just exec'd something
that isn't there.
First you have to load the kernel
fis load vmlinux
THEN you do the exec ....
exec -c "console=ttyAM0,115200 root=/dev/mtdblock1"
These commands can be done from the Redboot prompt - it is ALWAYS good to
manually testing things before committing them to fconfig.
If this works to get you back to booting from flash, then try
fis load vmlinux
exec -c "console=ttyAM0,115200 root=/dev/hda1
I assume you have partitioned the CF disk and created an ext2 filesystem on
the first partition, and then copied across the root filesystem?
