Setup

launch.json:

"configurations": [
    {
        "name": "Debug with OpenOCD",
        "cwd": "${workspaceFolder}",
        "executable": "${workspaceFolder}/build/Debug/ACU-25.elf",
        "type": "cortex-debug",
        "device": "STM32G474RE",
        "servertype": "openocd",
        "configFiles": [
            "interface/stlink.cfg",
            "target/stm32g4x.cfg"
        ],
        "searchDir": [],
        "preLaunchTask": "CMake: build",
        "showDevDebugOutput": "none",
        "svdPath": "${workspaceFolder}/.vscode/STM32G474.svd" // optional
    }
]

settings.json:

• add "vscode-serial-monitor.customBaudRates": [1000000]

c_cpp_properties.json:

• ensure you have the correct compiler path settings to arm-none-eabi: "compilerPath": "/opt/homebrew/bin/arm-none-eabi-gcc", (MacOS)

Build & Debug

• Press Build
• Press Debug
  • if Debug doesn't work, open terminal in VSCode and run
  • openocd -f interface/stlink.cfg -f target/stm32g4x.cfg -c "program build/Debug/ACU-25.elf verify reset exit"
  • if it still doesn't work, try removing the 'build' folder and configuring and rebuilding, sometimes cache stuff can screw u over
