DEBUG OUT Connector (P19) and VCOM0

[Bret Foreman]

I've got an nRF52832 DK board. When I connect it to the USB bus, I see the following in the nRF Connect app:

I can run the hello_world app and see it output "Hello World! nrf52dk_nrf52832" on COM4 connected to Tera Term.

Next, I connect my new target board to P19. Then I see this:

The new target is based on the 52810 so all looks as expected.

Then I used the "Create a new board" wizard in nRF Connect to make a build configuration for the 52810 SoC.  And I rebuild the hello_world app and flash it to the new target.

But nothing comes out of VCOM4.

I suspect this is because the VCOM4 is still pointed at the 52832 on the DK board. Is there a way to change the jumpers on the DK or the build configuration to allow VCOM4 to work with P19?

Regards,

Upon further research, it looks like this case: devzone.nordicsemi.com/.../uart-log-output-through-debug-out is asking the same question. And it looks like the advice there was to access the UART on the new target board for TX and RX. But that was 5 years ago. Is there a better way to do this now?
