No output with Segger RTT

[vChavezB]

I havent used before the Segger RTT feature so I might be doing something wrong.

My problem is I do not get anything on my terminal (J-Link RTT Viewer).

I built the debug version of ZSwatch and followed the tutorial from here to use the Segger RTT Viewer

https://blog.golioth.io/use-rtt-with-zephyr-when-console-output-via-uart-just-isnt-convenient/

My problem is I just get RTT Viewer connected but nothing on the terminal output.

I am using the Dock PCB for debugging.

By specifying https://github.com/jakkra/ZSWatch/blob/main/app/boards/debug.conf when compiling should be enough to get RTT working, it used to work, but have been using UART for a while. I'll give it a try myself again.

Works for me. Sometimes After a reset you need to re-connect the RTTViewer to get the logs back (File->Connect or press F2), I don't know why this is sometimes needed.

thanks for the feedback, will try again and see if it now works.
