Update: - NetBSD 9.99.85 evbarm-earmv6hf 202106170850Z rpi.img from nyftp. - Raspberry Pi [0-3] have been supported in big-endian mode (Rin Okuyama) XXX: should test big-endian image and pkgsrc
earmv7hfeb works fine so far, pkgsrc included. aarc64eb doesn't boot on a Raspberry Pi 3, but I'll send more details about that when I collect them.
Thanks! John
