[U-Boot-Users] BMW Platform, PPCBoot version 1.2.0

[U-Boot-Users] BMW Platform, PPCBoot version 1.2.0

[Vasu Dev Dasari]

Hi,

I am using BMW platform with PPCBoot version 1.2.0. I
am seeing a very strange behavior after system
powerup.

1. After powering up the target, it goes into
auto-boot mode. I configured it to use tftp to
download an image file. Unfortunately I entered some
wrong parameters in the environment variables. So, I
wanted to correct them. 

2. When the system is auto-booting, I pressed Ctrl-C
system takes me to a prompt. Then I tried to set the
variable. After this operation, entire environment
variables disappear.

3. I am including my console output here. I am not
sure how to come out this either. Plese help me.
