First, I have an RasPi 3 which I've tried to get running with OpenBSD. I'm running into the previously noted USB flash drive issues where Uboot does not recognize some flash drives. I've installed OpenBSD on several flash drives but can't boot any.
I'm looking for recommendation for supported hardware that does not have h/w oddities like RasPi 3. I want to use an small arm64 box as a relayd system in front of a single system. From the list of supported hardware on http://www.openbsd.org/arm64.html which is the best supported with a minimum of issues? Also, after reading Patrick Wildt's twitter page I see there may be additional functioning hardware. thanks diana
