	I am trying to get my JLink-Ultra working with VM, I have tested the JLink GDB server and it connects to my target (Portenta H7/M7) just fine. Also, I watched the YouTube videos, however, my VM does not show JLink as an option for hardware debugging. My preference is to keep the Segger driver and use the GDB server. Advice most welcome, Sid

	Thanks for the report. Can you confirm the GDB Commands, and JLink settings you have used so far, so we can be sure we integrate the same settings for this board/core? It can be integrated using the Manual/Custom option before we add the menu option, more information on that can be found here: https://www.visualmicro.com/page/Debugging-Using-Custom-Hardware.aspx

	Hi Simon, I have created the launch.json file using the link you gave as a guide. This is what I have: Code { // Modifications for using Segger JLink Software instead of OpenOCD with vMicro "serverLaunchTimeout": 5000, "filterStdout": false, "filterStderr": true, "targetArchitecture": "arm", "stopAtEntry": false, "externalConsole": false, "MIMode": "gdb", // NOTE - The GDBServer address default is 2331 for Segger "MIDebuggerServerAddress": "localhost:2331", "cwd": \\Debug", "MIDebuggerPath": "C:\\gcc_arm\\bin\\arm-none-eabi-gdb.exe", "MIDebuggerArgs": "", // NOTE - Your path may differ for your Segger Software Installation "debugServerPath": "C:\\Program Files\\SEGGER\\JLink\\JLinkGDBServer.exe", // NOTE - Ensure the right -device is specified - check tool setup by running the above tool in Windows "debugServerArgs": " -select USB -device STM32H747XI_M7 -endian little -if SWD -speed auto -noir -LocalhostOnly", "program": \\Debug\\Visual_Micro_test_1.ino.elf", "logging": { "moduleLoad": false, "trace": false, "engineLogging": false, "programOutput": false, "exceptions": false, "traceResponse": false } } I still do no see a menu op0tion to use this Debug configuration. I restarted VS2019, but that did not help. Sid

	Thanks for the update and JSON file. Once you have configured the launch.json in your project, setting the Hardware Debugger to "Manual/Custom" will use this configuration. I'll update when we have more news on the integration of this into a new menu option.

	Thank you, it is kind of working. A couple of points: When using the "run" command the code is not flashed using the GDB Server, it still requires the board to be placed into bootloader mode manually. The "Attach to Process command does not set breakpoints in the code. Sid
