I think i messed up with armbian-config, namely with 'system' sub section. I noticed that lately the only images that boot are armbian with kernel 6.9.x Nothing, i say nothing with a lower kernel number would boot -- even those SD cards that were good last time i tried them. None of orangepi factory images boot. In and out of itself, it is not a problem. Yet. But what if something changes in a future?
