Re: When will FreeBSD support RPI5?

I was able to boot FreeBSD-14.0 on an rpi5 using EDK2 from
https://github.com/worproject/rpi5-uefi. I put the EDK2 firmware on an SD
card and an aarch64 memstick image on a USB thumb drive and was able to
boot all the way into the installer. PCI express is missing as well as
ethernet but it's a really promising start.
