Installed Armbian Buster, an excellent OS project supporting over 300 boards, and has an awesome setup tool including hotspot config.
Couple of difficulties along the way, their "headless" OS needs tweaking to actually be headless cuz by default you need to enter a new password on first boot before even ssh access is possible! Needs an ext antenna too.
The new Banana Pi is going very well, the hotspot signal is very good with a small antenna attached. And today I change the root fs over to an SSD on the SATA port which is faster and mitigates the risk of SD card corruption.
ODing in the fediverse!
