RE: [U-Boot-Users] Start up problem with PPCboot 1.2.0
Hi again, I solved the problem by flashing the two other boards with PPCboot 1.1.6 , now everything works fine.
After 1.1.6 I will go for the u-boot distribution.
Thanks // Matias

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.

Dear Matias,

Argh... that was NOT necessary.
Sorry that I didn;t find the time to reply earlier.

You should do that anyway.
But it is even more important that you understand that it was a user error that prevented your board from booting as expected:
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
I doubt that this was the actual setting of the "bootargs" variable:

Here you can see that ABSOLUTELY NO arguments were passed to the Linux kernel. This makes me believe that you did NOT set "bootargs" at all.

Such a setting "cannot happen". If you attemot to set a variable to an empty string this means the variable is deleted from the environment.

All these empty variable values are "impossible". The only way such a thing can happen is that there are some unprintable characters (like terminal escape sequences) embedded.
I can only speculate, but I am 99.99% sure that you used (or tried to use) cursor keys etc. when entering the environment, therefore entering a lot of invalid characters.
The same must be the case for the bootargs variable - I bet there are some unprintable characters embedded in the vaiable name, so it does not get recognized when booting the Linux kernel. You can verify this by typing "printenv bootargs" - I bet a case of beer that the variable will not be found. Or somebody meddled badly with the envrionemtn processing code.
