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

--> 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

The bug report says to do a little bit different operation :

"A simple workaround is to duplicate bcm2710-rpi-3-b.dtb with the name
bcm2710-rpi-zero-2-w.dtb"

bcm2710-rpi-3-b.dtb and bcm2710-rpi-3-b-plus.dtb have different sizes.
I suspect that one of them will not work.
