I try to install HAOS on a cm4 populating the official io board (not yellow) without succeeding.
The two routes I have tried is:
Method 1: Using rpiboot, flash the haos image “Home assistant OS 14.2 (RPi 4/400)”. The installation completes, HAOS boots but no cm4/ioboard hardware works. The wrong dtb etc is configured in config.txt. Even if I manually change the device_tree to “device_tree=bcm2711-rpi-cm4.dtb” HAOS still reports it as an RPi4, not cm4.
Method 2: Using rpiboot, flash the haos image “Home assistant OS 14.2 (yellow)”. The installation completes, HAOS boots and some of the cm4/ioboard hardware works. I believe this is not configurable as long as the wrong dtb etc is configured in config.txt (device_tree=bcm2711-rpi-cm4-ha-yellow.dtb).
What is the correct, or best, route to take? Should I modify either of the above installations to fit my hardware or is there a correct way to install I still haven’t found?
As far as I can tell the official io board for cm3 and cm4 is supported from this github issue.
I have searched a lot for a solution but cannot find one that works, and hope someone here can clarify if this even is possible, and if so how. Thanks a lot in advance.
