To be sure, I generated a pure 4.5-rc1 kernel. Same result: no UART. Maybe... one more information: I am using Allwinner's u-boot.Could be that that is the culprit, why are you not using upstream u-boot? upstream u-boot has H3 and orangepi-pc support now.Yes, but using the upstream u-boot may hide the clock problem.I agree that that could be the case. Would be interesting to figure out what exactly is needed to get the upstream kernel to work properly with allwinner's u-boot.
I'm guessing it's probably because of the arch timers that have not been properly initialized. Do you have any earlyprintk output?
