Yes, I know, I had set it to some bogus address but that didn't help either...
How can the mac address be missing anyways, shouldn't that be fixed in sillicon?

I did the key combo when the usb was plugged in and now, not even uboot boots up 
anymore, it seems to be completely blank now. When I launch sam-ba as root (on Linux), I 
can only select Exit, nothing else is enabled. "Select the connection" seems to be enabled 
but is empty, nothing there to choose. Also dmesg doesn't show me anything on powert 
reset... what else can I do from here? :o

Thanks,
Ron
