Sending log message from nRF5340 custom bard to PC via nRF5340 DK

[gwan0624]

Hello,

I am planning to design a custom board using the nRF5340.

My main question is: How can I view log messages from source code running on the custom board on my PC?

Previously, I was able to view log messages on my PC from nRF5340, via Interface MCU (also nRF5340) on nRF5340 DK.

However, I am unsure if this is feasible with a custom board.

I plan to connect the nRF5340 DK to my custom board via the SWD interface
(using a total of 5 pins. VDD, GND, SWDIO,SWDCLK, RESET).

I understand that debugging and programming should be possible with this configuration.

However, will this setup also allow me to transmit log messages to the PC?

I would like to know if the current wiring is sufficient, or if there are any additional pins that need to be connected between the custom board and the nRF5340 DK.

Thank you.

J-Link RTT viewer would work if your project was properly set up for RTT. Can be tested with a DK.
