Re: Radxa Zero and FreeBSD : happy marriage ?

from my point of view, 32bit platform is not a big problem.

My roadmap of similar project is to port fbsd to stm32mp1 (booting is 
done, while mounting root requires SD driver, which I decided to leave 
in secure TZ, rewriting fsbl for that reason) and expose SD to the 
kernel as a trivial char device (may be some kernel glue).

As for the video, I chosen DSI interface, but have not tested custom 
screen I ordered for it yet. At least I hope to create kind of 
"suppported" hardware environment to be able to boot FBDS, Linux, etc.

So, I see no problems using 32bit as playground. Familiarizing myself 
with some aspects of fsbl/tz/power management and then go further to 
stm32mp2, which may become a 10+ years old smartphone with FBSD targeted 
towards security, modularity, openness.

(my project will not require video nor battery). but you know all that i see. this is not first time. i think openmoko freerunner poorly ran fbsd too, my friend had that working i recall. how you're going to pull it off i have no idea. i'm not good in any of those fields either. happy to test something tho. have a good luck with this masterpiece
