BPI zero uart3 - how to enable?


(Ian Betts) #1

I am running the latest armbian-ubuntu image and try to make simple loopback test on UART3. (pins 8 and 10 on header) Using minicom I try with /dev/ttyS1 through 7 and no success.

Questions:-
which number ttyS is uart3 ? what must I do to enable it ?

Thanks
