I have a problem, I would like to change the MAC address on the mini2440 but I can't get it working. I use u-boot and the command "set ethaddr 08:00:2f:00:00:02" and saveenv, but if I change the MAC in that way, I can't get any network connection anymore in debian. I think the MAC needs to be changed in u-boot, but how? Is it possible to change when it already is compiled (u-boot running) or do I need to compile it with different settings? u-boot/drivers/net/dm9000x.c seems to be the file for the network card, but I can't find any mac address there.
