Having Issue with Using Segger j-link/ozone

[KurtE]

I have had some luck with it:

Some of the notes about it are up in the thread:

Source level debug - IDE2 - GIGA R1

Hi Kurt, I guess you are using the Arduino IDE? You have a couple of options as I couldn't get the Arduino IDE to debug the giga, it just looks like it is not supported: Use PlatformIO and the jlink using cortex-debug. Use Arduino but use the Segger Ozone debugger: https://docs.arduino.cc/tutorials/portenta-breakout/breakout-jlink-setup The Giga R1 is not a supported board in PlatformIO, I have a PR put in to add it but who knows if that will ever happen. If you want to get PlatformI…

The post by @BobTheDog gave a link to how to set it up for the Portenta which worked for me.

You might also double check your cable connecting from the J-link to the GIGA, that they are connected correctly. Also I had sometimes when it did not connect, which improved after I swapped the cable with one that came from some debug clone that @ptillisch suggest awhile ago to be able to debug a different board.
