[U-Boot-Users] MAC address setting

Hi all!

I have custom designed ARM board, based on AT91RM9200EK reference design. Hardware works fine. And I have following problem: When U-boot loads Kernel image from tftp, everything fine. When U-Boot starts kernel from flash, then Linux cannot communicate to ethernet device. I understand, that this is because MAC address was not set by U-Boot. But I could not find a command to initialise Ethernet. Please advice, how to act.

Best regards, Jevgeni
