[U-Boot-Users] Unable to store environment variables
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.
- S u d e e p V A system of morality which is based on relative emotional values is a mere illusion, a thoroughly vulgar conception which has nothing sound in it and nothing true. -Socrates.
After power on the initial u-boot prompt looks like this: => reset

More than likely it's just like the message says:
Error: start and/or end address not on sector boundary
and your not on a sector boundary.
Go into your include/config/"whateveryourboardiscalled.h" file and edit
#define CFG_ENV_ADDR #define CFG_ENV_SIZE #define CFG_ENV_SECT_SIZE
So that the enviornment starts and ends on a sector that is not inside u-boots code space and you should be kewl. It will need to take up a whole sector.
I don't completely know your system's memory map, but I'd guess
#define CFG_ENV_ADDR FE040000 #define CFG_ENV_SECT_SIZE 40000 #define CFG_ENV_SIZE CFG_ENV_SECT_SIZE
