[U-Boot-Users] Unable to store environment variables

[NZG <ngustavson@emacinc.com>]

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          

NZG.
