Serial Terminal over GPIO Pins

[RodWatt]

Hi,

I am running my nRF9160 DK in "nRF Only Mode" (Via SW1). I would like to drive the serial terminal out via one of the GPIO pins, connected to my MAC using an FTDI serial to usb cable.

I am using this cable to power the board and have connected the TXD and RXD wires to P0.25 and P0.26. 

I have referred to this post which details the overlay and proj.conf settings

https://devzone.nordicsemi.com/f/nordic-q-a/49093/configure-second-uart-on-nrf9160-dk/195746#195746

I have followed this but unfortunately and still not seeing a serial output.

Is there anything else Im missing?

Thanks,
Rod

I managed to get this working.

I added the following code to the overlay file in nrf/samples/nrf9160/spm

&uart0 {
	current-speed = <115200>;
	status = "ok";
	tx-pin = <25>;
	rx-pin = <24>;
//	rts-pin = <12>;
//	cts-pin = <13>;
};
