[U-Boot-Users] Start up problem with PPCboot 1.2.0

Thu Aug 14 13:58:15 CEST 2003

Comrades,
I have three BMW (WhiteKnight) boards from Broadcom.

In one of them PPCboot 1.1.6 is used and everything works fine,
but on one of the others I have PPCboot 1.2.0 and I never get 
passed the ,

IP-Config: Incomplete network configuration information....

I thought the bootargs parameter should supply the Linux kernel with 
it's parameters,

bootargs=root=/dev/nfs rw nfsroot=130.100.50.56:/tftpboot/130.100.50.55 ip=130.1
00.50.55:130.100.50.56::255.255.255.0:::off

It seems to work on the 1.1.6 version though, can someone advice me 
what to try next?

Below you can see the start-up attempt and all the environment variables used/set.

Regards // Matias
