Those are images from BigTreeTech, not Armbian. Official Armbian images for CB1 are here: https://www.armbian.com/bigtreetech-cb1/ If you want to use vendor images, you should report your issue to BigTreeTech then.

Yep, looks like it's about the netplan renderer. I've tried the actual image instead of the one I built locally and even just a reboot is able to reproduce the issue. The main difference is that on the image I built networking was via NetworkManager by default, while the image on the website uses systemd-networkd.

I am unable to reproduce this on BigTreeTech Pi (v1.2). Set wifi up using netplan via NetworkManager. Wifi connects after a reboot, same if I poweroff the device, disconnect power and then connect back up.

No idea what causes this, will need to check on my device

I'm not working on the legacy kernel at all, current and edge only, which are based on mainline. The fix for wifi should be in the upcoming armbian release (25.05). It was merged into the build repository long ago and should've been available in beta already, only now coming into the release. To those who are still using legacy - I recommend switching to current or edge instead.

Have you tried with current or edge kernels?

Found the issue and submitted a PR to the repository. It will take some time to get merged and then the new kernel built and put into the apt repository.

It seems that the images mostly just use some of Armbian patches, maybe some custom ones. Comparing them thoroughly and applying what I can if needed is my goal now.

First time seeing this 3.0.0 image, will check it out

@Yell BigTreeTech images are like a reference image made by bigtreetech, it doesn't have the long-terms support and usually uses old kernel versions, simply an image to use when the board was just released. The other link is a link to my forked repo where I did work on the board before it got merged into the main branch, it's a temporary branch and you should not use it. I recommend using the official Armbian image as that is what is supported on this forum, you can download it on the armbian website (armbian.com)

The patch has been added: https://github.com/armbian/build/pull/7584

I've had a person contact me on discord saying that using a orangepi 3b image with a slightly modified device tree works well, I've also mentioned that in the PR discussion. You can try that. My current goal is to translate the modifications they made onto a normal (non-flattened) device tree source and maybe include something from orangepi 3b to hopefully fix that issue, but it's a long process and I've been having some health problems recently. I want to use BTT Pi2 as a new home server, especially since the sd card in my old one died and now I am in a hiatus of trying to recover and get up and running.

The btt-cb2 branch is currently not working, hangs 170 seconds after boot, and I am working on fixing the device tree for that. BTT CB1 is a different hardware, and it's in the main branch. I handle them separately because of the different SoC families.

Sorry @Sesse but I don't know an answer to that question. You'll have to ask someone else for the reasoning behind that. I'll ask in our discord channel.

Oh crap, forgot to subscribe to the topic. Thanks @going for your work on this!
