Hi:

I’m using uboot-1.1.4 for AMCC PPC440E Yosemite = board. I’ve downloaded this uboot from DENX site. It uses EEPROM to store environment variables. Since EEPROM on Yosemite board is only 512 bytes, there can not be more environment variables = which is not very convenient.

There is theoretical possibility to save these = variables on flash (64M from which I use only part) and yosemite.h header file even = has defines, allowing this option. But is it going work in reality? What is simplest = way for Yosemite board to increase = environment variables storage space?

Thanks,

Leonid.

AMCC eval boards - two redundand flash sectors to store the environment. And available environment size is 8 kB: => print ...

I have no idea where you got your board configuration from, but it is definitely not current code, nor the binary image at ftp://ftp.denx.de/pub/u-boot/images/amcc/yosemite/u-boot.bin The current code does use (redundand) flash for environment storage.
