3B+ No ethernet after update

Postby nalyd » Fri Sep 06, 2019 3:40 pm

Hello, I'm just posting here because I ran into the issue this morning and figured it might help someone.

I'm using AArch64 on my 3B+, and the raspberrypi-bootloader-20190904 update causes my Pi to boot without ethernet. I see something about `address not set` during the bootloader phase despite that I do have a static IP in my config.txt.

Anyways, to fix this I just rolled back the bootloader to last week's version like so:
Code: Select all
sudo pacman -U /var/cache/pacman/pkg/raspberrypi-bootloader-20190828-1-any.pkg.tar.xz

If anyone has any more insight into the issue that would be great

Same problem, the MAC address is set to 00:00:00:00:00:00 with the 20190904 bootloader package so it breaks any setup that isn't over-riding the MAC address

Can also confirm. Running the "linux-aarch64" kernel.

The last working version I have is:

The next one I have, and it fails is:

Also the following fails:

Thanks for pointing out the issue regarding the unset MAC address.
My quick fix to avoid the rollback is to create a file /etc/systemd/network/00-default.link with the following content:


NamePolicy=kernel database onboard slot path

where realMac is the MAC address of your Raspberry Pi, you can usually look this up in your Router.
It's the approach described in the Arch Linux Wiki here: https://wiki.archlinux.org/index.php/MAC_address_spoofing#systemd-networkd.
The advantage here is that you don't need to rollback and you can also do this from another computer just by mounting the SD there.

Kind Regards,
