vscode cortex-debug launch.json gdb external configuration, how to have the right parameters

The goal is to have a remote debug session configured and running from vscode with nrf52840 mcu.

I am at the moment configuring a remote debug session on an internal LAN network (out of a docker devcontainer) with:

Here is the launch.json configuration used:

{
    "version": "0.2.0",
    "configurations": [
        {
            "cwd": "${workspaceFolder}",
            "executable": "${workspaceFolder}/application/_build/application.out",
            "name": "Debug devcontainer launch",
            "request": "launch",
            "type": "cortex-debug",
            "servertype": "external",
            "gdbPath": "/usr/bin/gdb-multiarch",
            "gdbTarget": "host.docker.internal:2331",
            "device": "NRF52840_XXAA",
            "runToEntryPoint": "main",
            "svdFile": "${workspaceRoot}/nrf5_sdk/modules/nrfx/mdk/nrf52840.svd",
            "showDevDebugOutput": "both"
        },
    ]
}

After starting the debug session I can see that:

  • The debug session actually connects to the SEGGER GDB Server running on the windows host, reads the memory and programs it in case of needs as the log proves it:
    • Connected to 127.0.0.1

Questions:

  • Do you have any inputs regarding the launch.json configuration and tools chosen?
    • Is it a good option, should I change something?
  • Is there some pre/post debug sequences I should add/adapt?
    • preLaunchCommands?
    • postLaunchCommands?
    • overrideResetCommands?
    • overrideRestartCommands?
    • postAttachCommands?
    • postLaunchCommands?
    • postResetCommands?
    • ect...
  • Any other inputs?

Thanks.

  • Hi,

    I would recommend that you use arm-none-eabi instead of multiarch, to avoid such problems.

    It seems that you initially break here:

    GDB -> App: {"output":"","outOfBandRecord":[{"isStream":true,"type":"console","content":"73\t    APP_SCHED_INIT(SCHED_MAX_EVENT_DATA_SIZE, SCHED_QUEUE_SIZE);\n"}]}
    73	    APP_SCHED_INIT(SCHED_MAX_EVENT_DATA_SIZE, SCHED_QUEUE_SIZE);

    But, you do not show any info on how this is shown in vscode, so it is hard to say what can be the issue, given that you mention single-stepping and stopping on breakpoints as a problem.

    Some GDB commands are somehow not expected by the J-Link GDB server as seen in the logs:
    • Received monitor command: reset halt
      Expected an decimal digit (0-9)
    • Any ideas regarding that?

    Looks like the cortex m debug plugin issues a "monitor reset halt"

      • postLaunchCommands?
      • postResetCommands?
      • ect...
    • Any other inputs?

    First I would recommend that you, from the container, connect manually using gdb:

    my-gdb path/to/.elf

    And in gdb:

    target remote ip:port

    backtrace

    print /x some_variable

    b main # set breakpoint at main()

    monitor reset

    c # continue until breakpoint it hit

     

    This is to verify that your debug connection is working. I haven't used multiarch-gdb myself, so I cannot verify if it actually works as intended with cortex m.

     

    Kind regards,

  • Hi Håkon,
    Thanks for the insights it helps a lot, here is what I did and the actual state:

    What I did: (All actions are made in the docker devcontainer)

    • Reinstalled the ARM GNU toolchain (x86_64 Linux hosted cross toolchains) from https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
    • Change the compilation optimisation flag in makefile from -O0 to -Og and recompiled everything
      #OPT_FLAG   := -O0
      OPT_FLAG   := -Og
      DEBUG_FLAG := -g3
    • Recompiled the firmware and flashed the target
    • Tried a remote command line GDB debug session, it seems it works, here is the outputs:

      As far as i understand, GDB connection to the target and GDB commands are working!
    • I overrid some monitor commands based on

    Question:

    • At the moment, i am flashing the MCU manually with the nrf programmer.
      • how can i automate this with gdb? (load command doesn't seems to work...)
    • Any other suggestions to add functionalities, script automation or other way to do?

    Thanks,

    Matthieu

    Yes, gdb is working as it should!

    "load" can be problematic if you have multi-image builds (mcuboot + app for instance).

    this is because it only updates the application part, and not the image as a whole.

     

    nrfjprog should have support for remote connections now, as shown in the release notes for v10.15.0:

    - (nrfjprog.exe) Added option "--ip" and "--port" for connecting to a network enabled debugger.

    You could try to use that. Alternative can be to use JLink.exe (J-Link commander) to remotely connect and download the binary.

     

    Kind regards,

    Håkon
