Well, after that command, the filesystem takes
place. You can't put anything in the kernel. The
procedure for calling and executing init works fine.
Is the root filesystem correct? Have you tried to
upload a ramdisk image in ram? If you are sure that
all these are correct, then do you have a JTAG
Debugger? (OCD Commander ...)
