This feels like a good place to ask this. Has anyone who sees this attempted to run Home Assistant OS in a Home Assistant Yellow "compute module board" using a Radxa CM5? It's tempting to me because the Radxa CM5 uses a mainline kernel instead of the Broadcom-modified kernel the RPi CM4 uses, but I understand that there may be some level of work needed to be done to support the compute module + board combo, and I'm curious if that is true for the Radxa CM5 + Yellow board combo. Or have I misunderstood anything?

I was tempted to do something similar when I got my Yellow because the low availability of the CM4s back then, but it seemed that, at least with older Radxas there were problems with kernels or compatibility. It might work with the newer one if you say it's mainline kernel but haven't found anything in the forum in quick search...

  I am keen to try. But I'm even more keen for someone else to tell me they have tried it and the result of said test because I am not keen on my home automation system being down for a longer period of time...

There is no "Broadcom-modified kernel". There's a fork with changes needed to support all Pi hardware at https://github.com/raspberrypi/linux https://github.com/raspberrypi/linux. Unlike some boards were you're eternally stuck at old versions, the fork is actively maintained (currently mostly at 6.6, soon 6.12) with its changes regularly getting upstreamed. You post make it sound like the Pi kernel is a mess, which it is absolutely not.

    Right. I read it as "modified by Broadcom". Just wanted to point out, that this isn't inherently a bad thing if done right.

      I get where you're coming from, didn't mean to make it sound like that but I do see it the same way zokier seems to. End game for me is booting a vanilla kernel compiled entirely from open source code and having access to all the boards hardware.
