Re: Raimbow screen installing / booting FreeBSD-14.2-RELEASE-arm64-aarch64-RPI.img on the raspberry pi zero 2w

The problem isn’t the fix — it’s that there is simply no appropriate device tree for the zero-2 that is bundled with the image so the board has no idea how to boot.

So, while not perfect, until someone from the projects adds a zero 2 dtb, I’m guessing copying one of the pi-3 images is your best bet (I just tried it and it works — well, boots, at least).

Best,
Marco
