Using a Second UART on Rock Pi S


I’m trying to develop a device capable of remotizing the UART of a slave device.

I have the rock pi on my network connected to another device and I would like to see its UART output.

I’ve installed minicom on the pi and activated uart2 on boot/hw_config

But the UART doesn’t seem to be working.

I do see some random chars when fiddling with the cables but nothing else.

Can anyone help me putting a uart working on the rock pi s?
