Printk output stopped working with nRF5340-DK

[cscase]

I'm having a problem where it seems I'm no longer able to get printk output to show up on a serial terminal. The projects build okay, and when I hit reset, I see the following line on the terminal:

*** Booting Zephyr OS build v3.2.99-ncs1 ***

However, if I debug and step through a program, when printk statements are run, nothing appears on the terminal.

I'm working with SDK version 2.2.0.  The project I am working on started from the observer example code.

Below are the contents of my prj.conf.

My devicetree overlay is empty, apart from comments.

Can anyone offer pointers as to where I should be looking to troubleshoot this issue? What does it suggest that I get the bootup message, but no output from printk?

Thanks!

Hi,

Are you looking at the correct COM port? The COM port for the network core will only output the boot line.

... That was it.  I had assumed that because I was seeing the boot message when resetting the board, I was on the right port. I feel silly for not having figured that out myself, but am grateful for an easy solution. Thank you, Øivind.
