Hi
After I applied your boot params it puts the lines below on the terminal.
What means 'Root-NFS: Server returned error -5 while mounting /tftpboot/' ??
Any ideas?
TIA, Ruedi

Thema: Re: ATA flash disk ok, missing ip config
Hallo,
I had some "IP-Config: Incomplete network configuration information." when the
boot line was not correct. This line must be entered after the "Linux/PPC load:"
prompt. A default line can be programmed in arch/ppc/boot/misc.c.
char *root_string = "root=/dev/nfs nfsaddrs=10.10.10.1:10.10.10.2
nfsroot=10.10.10.2:/export/nfslinuxroot
where 10.10.10.1 is the IP address of the ethernet interface of the board and
10.10.10.2 is the IP address of the workstation from which the root directory is
exported via NFS.
Does that help ?
Regards,
Amre
