Is possible to use the DEBUG UART, as a normal UART to other applications, like communicate with GSM modem/GPS

[Marco Otavio]

I want to use the OPI3, but I need 2 uarts, in 26 headers there is 1 availabe, but I need one more. Is possible to disable the debug, and use it for my application?

Try setting console=display in your /boot/armbianEnv.txt file. That should free the 3 pin uart for other use within linux. Please note that the 3 pin uart will still be used during booting by u-boot, ATF and crust.
