thank you for creating and maintaining Armbian. Makes live much more easier. I installed Armbian 4.5 (Cubietruck Jessie 4.2.3) via UART0.

I understood as Armbian uses the mainline Kernel script.bin is now obsolete and no longer used. Thus I don't know the pinouts for the other UARTs. Is there any documentation?
Furthermore I'm not sure if the other UARTs are properly enabled in the Kernel configuration.
Linux serial console seem to be on ttyS0 which is working fine:
