BlackMagicProbe not working

[Fabien-B]

Hello,
I have an issue using cortex-debug on VSCode.

If I run theses commands in a terminal, it works has expected, and the program pauses at the start of the main function.

/opt/arm-gcc/bin/arm-none-eabi-gdb

file obj/debug.elf
target extended-remote /dev/bmp-gdb
monitor swdp_scan
attach 1
load
b main
run

However, launching a debug session with this configuration does not works:

{
    "version": "0.2.0",
    "configurations": [
      {
        "name": "AM32 BMP",
        "cwd": "/home/fabien/dev/AM32-bootloader",
        "executable": "/home/fabien/dev/AM32-bootloader/obj/debug.elf",
        "request": "launch",
        "type": "cortex-debug",
        "runToEntryPoint": "main",
        "servertype" : "bmp",
        "BMPGDBSerialPort": "/dev/bmp-gdb",
        "armToolchainPath": "/opt/arm-gcc/bin",
        "showDevDebugOutput": "raw",
      }
    ]
  }

Trying to add other breakpoints does not change the behavior.

toolchain version:

• Cortex-Debug Version 1.12.1
• OS: Linux Ubuntu 20.04 LTS
• GDB / Toolchain Version: GNU Arm Embedded Toolchain 10.3-2021.10
• BMP version: Black Magic Probe v2.0.0-rc2-40-g5408212b, Hardware Version 3

Here is the full raw output from the debug console:

My first inclination is to see if you can tri the latest pre-release

https://github.com/Marus/cortex-debug/releases

We don't have any BMP HW, so, I cannot debug your issue. Maybe someone else can pitch in and help.

You can see every command we are sending to the BMP, you can replace those with your own using overrideXXX settings in launch.json
