If you want to use your Segger JLink to debug the Portenta H7 on both cores simultaneously, this is the place to start!

This allows you to stop and inspect both cores as they run at the same time using a single JLink probe.

Using the Breakout Board for the Portenta H7, you gain access to the SWD Port allowing GDB Debugging to be performed through the Segger JLink in this example.

Additional connectors are needed (links below) to connect the Breakout Board to the JLink, and with a few simple steps you can debug your M7 Core Sketch using Visual Micro in Visual Studio.
