Hello,
Im trying to get 2 Uarts working on an Orange Pi Zero+2. Im using armbian Buster image for OPiZ+2
Linux orangepizeroplus2-h3 5.4.43-sunxi #20.05.2 SMP Mon Jun 1 18:26:22 CEST 2020 armv7l GNU/Linux
I added UART1, UART2 and UART3 to armbianEnv.txt and was able to read / write on ttyS2 on pins 8 (PA00) and 10 (PA01).
But couldnt find which pins ttyS1 or ttyS3 are on.
I read at that UART 3 should be
Tx PA13 Pin 24
Rx PA14 Pin 23
Is anyone able to suggest which pins I can use for a 2nd UART and is there a file I can look in to find the configuration for the UART Overlays ?
Thanks
Chris

Sorry, my mistake with wiring.
ttyS3 does work on
Tx PA13 Pin 24
Rx PA14 Pin 23
So armbian UART overlays working as required.
