The SOpine module boots perfectly from latest arm64-aarch64-PINE64-LTS image when running in both Pine64 Baseboard and Clusterboard, but when running in the latter the network interface doesn't work. This is a well known problem with the FDT which requires a small DT overlay, as documented here (this "tx-delay-ps = <500>" part is the fix): https://nixos.wiki/wiki/NixOS_on_ARM/PINE_A64-LTS#Clusterboard_Ethernet As I don't have much experience building FreeBSD image for arm64, I can't provide a ready patch but with a little bit of guidance I'm sure I can add the DTO and test it on actual hardware.
