[fedora-arm] RPi3 MAC address

[Alessio Ciregia]

I'm using Fedora 26 on a Raspberry Pi 3.
Is it normal that at each reboot (or shutdown and poweron), the MAC address
of the Ethernet card is each time a different one?

There is a place where to specify the MAC address of the Ethernet card?


Thanks
A.

What versions of kernel and u-boot do you have?

No. Should be derived from the serial number.

There used to be a uboot bug though where this didn't work correctly,
in that case the kernel generates a random mac for the device.

uboot v2017.05 should work correctly.

cheers,
Gerd

There was a issue in the kernel that was fixed in
10b6c0c2e2bb8cd1be682f8d36ef597e3419cb88

We pulled this is some time ago as well.

P.S. I am using U-Boot 2017.05-rc2 and kernel 4.11.5-300
The U-Boot came in the .xz file and the kernel cme in the first dnf update.

Thanks!

So there was fixes in both u-boot and the kernel to deal with this
problem so please update it to the latest version. You can do this
easily by running the rpi-firmware-update command which will update
u-boot and the RPi firmware to the latest version.

That fixed it! I had run rpi-firmware-update on Fedora 25, but forgot to run it after installing Fedora 26 beta. Perhaps I should have run dnf update user-brain -y :-) Thanks!
