Unable to start debugging. No process is associated with this object.

I imported the project \boards\evkmimx8mp\rtos_examples\freertos_hello from the SDK, but I'm not able to debug it. The only probe connected to my PC is J-Link PLUS Compact, visible under DEBUG PROBES When I selected Debug for the first time, no prompt are asked to me, and in mcuxpresso-tools.json the following item is set

"debug": {
    "linkserver": {},
    "pemicro": {},
    "segger": {
      "device": "MIMX8ML8xxxKZ_M7"
    }
  },

But after a while, the following popup appears Moreover, it seems that Reset debug probe selection has no effect.

In another project \boards\evkmimx8mp\multicore_examples\rpmsg_lite_str_echo_rtos (imported from the SDK), when I selected Debug for the first time, I was aked to select the Device and Cortex-M7 is available. After I selected it in mcuxpresso-tools.json the following item is set

"debug": {
    "linkserver": {},
    "pemicro": {},
    "segger": {
      "device": "Cortex-M7"
    }
  },

I can debug this project successfully.

Any idea on the reason?

Hi,

We are looking into the issue, we'll come back with an answer.

Hi,

We couldn't reproduce the issue, we were able to debug this target. The only difference in our environment is that we tried on JLink Plus, we don't have in this moment a Compact type. Can you please go to launch.json in Settings and set to "true" the "engineLogging" property then to redo all the steps until you get the error and send us the resulted log in Debug Console?

Regards, Cristian

Hi @cristitep-nxp here is the log debug_console_log.txt

I also encounter this issue frequently. Restarting vscode makes the problem go away.

In case it helps, this is the official documentation from Segger on how to configure launch.json to debug the target using J-Link probe.

Where do I find the svd files? I've been debugging without them and I have no view of the peripherals. The plug-ins from other vendors automatically select the svd, not sure why MCUxpresso hasn't done so..

[DerekSnell]

Hi @asteriskSF , SVD files are included in an MCUXpresso SDK package for a device or a board. The files have .xml extensions. You can also find them in the MCUXpresso SVD repo.

For more details, please see the Lab Guide for Zephyr Debugging with VS Code for more details.

Best regards

@DerekSnell is there a recommended place to put these in a west based zephyr project? I see there is a already a module for nxp's hal in modules/hal/nxp...

[DerekSnell]

Hi @asteriskSF , When using the MCUXpresso extension for VS Code with a project based on the MCUXpresso SDK, the SVD file will automatically be setup in the JSON file for the debugger.

When debugging a Zephyr project, today the SVD file is not setup automatically. You must download the SVD file locally, and manually modify the JSON file to include that SVD. In that case, the location of the SVD file is not important. It is not included in the build, and you just need to tell the debugger where to find it. Personally, I like to include the SVD file in my application repo, so it is easily available when that repo is cloned.

Best regards

Thanks @DerekSnell to make this consistent for the other developer on my team, I added the nxp-mcuxpresso repository into our west.yml in our out-of-tree repository,

For anyone else interested, these are the modifications to my west.yml

  remotes:
    - name: nxp-mcuxpresso
      url-base: https://github.com/nxp-mcuxpress

  projects:
    - name: mcux-soc-svd 
      remote: nxp-mcuxpresso
      revision: main

Then in my app/.vscode/launch.json I have an absolute path to the svd file, perhaps this could work with a relative path..
Here is my launch.json:

{
  "configurations": [
    {
      "type": "cppdbg",
      "name": "Debug project configuration",
      "request": "launch",
      "cwd": "${workspaceRoot}",
      "MIMode": "gdb",
      "setupCommands": [
        {"text": "set remotetimeout 600"},
        {"text": "set debug-file-directory"}
      ],
      "program": "",
      "miDebuggerServerAddress": "", // Remote GDB server address. If this is provided, "debugServerPath" will not be auto-completed.
      "variables": {
        "mcuxStopAtSymbol": "main", // Initial breakpoint
        "mcuxSerialNumber": "727866252", // Probe serial number. If not specified, the one from the selected debug probe (in extension view) will be used.
        "mcuxAttach": "false", // Start debug in attach mode
        "mcuxRemoteProbeType": "", // Remote Probe Type ("LinkServer", "SEGGER", "PEmicro") used only when connecting to a remote server
      },
      "svdPath": "d:/zrtos_workspace/mcux-soc-svd/MIMXRT1062/MIMXRT1062.xml",
      "logging": {
        "engineLogging": false
      }
    }
  ]
}

@DerekSnell Can you advise how to get correct kconfig generated preprocessor macros to be used for syntax highlighting of source files in VSCoce with MCUXpresso for VSCode?
