This means that you have a serious configuration problem in ypur U-Boot port: the U-Boot binary should never contain any MAN accress at all. I recommend to fix this now. > Firstly, I think I can gives out a random MAC as we need, but I can > not find any rand() or srand() > function in U-Boot. Instead of doing random things you should read the FAQ, especially here: http://www.denx.de/wiki/view/DULG/WhereCanIGetAValidMACAddress > Is there a chance that I can do this random job when U-Boot starts? You are not supposed to do that. For testing, you can use the gen_eth_addr program in the tools/ directory to generate "locally administered" MAC addresses, but these are NOT suitable for productions boards.
