OrangePiPC uart to Serial Ports

[Maxim Lisii]

HI,

I have OrangePiPc and need to activate 3 uart (TX-RX) pins as system serial ports (/dev/ttyAMA0, /dev/ttyAMA1, /dev/ttyAMA2)
how do it?

Armbian is proper Linux and UART ports in our world are named as expected /dev/ttyS0 /dev/ttyS1 ...

Simply use DT overlays declared as "overlays=uart1 uart2 uart3" in /boot/armbianEnv.txt.
