Variable Ethernet MAC address - gsinjari - 04-10-2016
Hi,
I have 64+ with 2GB, and I did noticed that every time I power cycle the board Ethernet is getting a different MAC address, anyone noticed the same?
I normally do MAC reservation and assign fixed IP to all devices I have home, but with this one every time I setup the reservation with MAC, next boot it kept using the old dynamic IP with new MAC address, this is first time I see a device like that.
I am using Arch Linux Image with XFCE4 Base, no HDMI output like most. I am sure it is the same board, same CPU.

Add a line:
ethaddr=xx:xx:xx:xx:xx:xx to /boot/uEnv.txt
where xx:xx:xx:xx:xx:xx is the mac address printed on the sticker on the board. If you don't like that particular MAC address you can assign whatever you wish, just make sure it is unique on your network.

Thanks, will try that once I got the board working again, it is not staying online, it seems to be in a power cycle loop.

Sorry, not trying to take credit. Couldn't figure out how to like the answer. :-) (like an idiot, didn't even think about pasting the link. )
RE: Variable Ethernet MAC address - Leoncito81 - 04-11-2016
I was looking at the boot log someone had posted on a different forum. Longsleep's build doesn't seem to set the MAC address for the Ethernet. I'm a relative newby to Arch, but I've never noticed this before.
