May 20, 20242 yr I've seen this question asked quite frequently here and all the posts end before there is a solution. I think it's time we had a crystal clear discussion on how it can be done. Not just for my curiosity, but for the people who've asked before and for the people who will ask in the future. The reason: Many hats/shields designed for RaspberryPi would otherwise be compatible with OrangePi if Armbian/u-boot didn't direct the debug output to UART0. UART0 is the most commonly used serial connection for hats/shields designed for RaspberryPi. OrangePi has multiple UART gpio so it would make sense for the O.S. (Armbian) to use the one that least impacts the users ability to actually use their hardware. Debug output is important but not so much so that the user cannot easily disable it.
