Subject: Re: zImage.elf loads but does not start

Thank you Andrei for your hint. I have hard-coded the mac address in the

arch/ppc/boot/simple/embed_config.c. Maybe it is not the most elegant
solution but it works.

Right now I was able to mount the root file system via nfs but it seems
to
be still somthing missing:

[    9.422162] Warning: unable to open an initial console.

To satisfy last problem "unable to open an initial console" I have
created
an entry in the /opt/eldk41/ppc_4xx/dev directory:

mknod ttyUL0 c 204 187
ln -s ttyUL0 console

I have rebooted the kernel once again and this time kernel has reached
the
point as listed below.:
 [    8.964390]      host=ml403-mirek, domain=, nis-domain=(none),
[    9.034414]      bootserver=129.129.130.106,

[    9.303794] VFS: Mounted root (nfs filesystem).
[    9.359316] Freeing unused kernel memory: 96k init

I do not know if the console was taken into account or not (the warning
has
disapeared but I am not able to ping
to my board nor telnet to it).

Any idea what could be wrong?

I use the root file system from eldk4.1:
/opt/eldk41/ppc_4xx/etc/inittab:
