Hello,

I am a newbie to U-Boot.

I am in the process of trying to load linux on the MPC8266ADS-PCI board. I compiled the u-boot code and flashed it in. The U-Boot comes up. But I am unable to save any of the environmental variables.

What should I be looking for ?? And what are the changes that I should be doing. Please suggest.

Details are as below.

After power on the initial u-boot prompt looks like this:
