getting Linux working on IBM Walnut demo board

[Brian S. Park]

Eran,
Thank you very much. Now the kernel comes up and I can ping the target. :)

Now to the next problem. I'm booting with NFS root file system. Below is
the bootargs that I'm using.

 >bootargs=root=/dev/nfs rw nfsroot=192.168.1.78:/home/ELDK/ppc_4xx
console=ttyS0,115200
 >              console=tty0
ip=192.168.1.146:192.168.1.78:192.168.1.2:255.255.255.0:netusb::off

exports file on my development station has
 >/home/ELDK/ppc_4xx      netusb(rw,no_root_squash)

/home/ELDK/ppc_4xx is where ELDK installed the target file system on my
development machine.
Even though I can now ping the target, I can't telnet to it. I get the
following error.

 >telnet netusb
 >Trying 192.168.1.146...
 >Connected to netusb.
 >Escape character is '^]'.
 >telnetd: All network ports in use.
 >Connection closed by foreign host.

Is this normal? Do I now need to configure the target file system to enable
telnet?
Or is there still something wrong with my bootargs?

Also, after the kernel comes up, I can no longer type any command through
the serial terminal.
The following the message at the end of kernel boot. It says it was unable
to open the console.

Any help will be appreciated.

Thank you

Brian
