Do user space program like init really don;t run, or is there any
chance that you just might see no output?
You can do a couple of things:
* Check your adaptions of the kernel source and your kernel configu-
ration is you really have a working serial console port.
* If booting over NFS realy works, you can try to start a (statically
linked small test program) that does something else but a printf to
the console. For example, open a file in /tmp for output and
frpintf to that file.
* Or start your test program with a known system call (like
gettimeofday() or maybe even getuid() etc.) and set a breakpoint at
the system call handler code inthe kernel.
You wrote "opening the console works" - set a breakpoint, and verify
that your console driver is really initialized and used.
