I don't see it listed in include/bsp/nexus-devices.h: which is where the devices used would be listed. FWIW I also don't see any arm/Pi configurations either. I could be missing something though. A first step would be to identify which NIC driver is used for the Pi4 on FreeBSD. This should help: https://wiki.freebsd.org/arm/Raspberry%20Pi Booting FreeBSD on the Pi4 would give you a boot log which should show a lot of the details about what needs to be configured. --joel > > Thank you.
