    "tasks": [
        {
            "label": "make",
            "type": "shell",
            "command": "make",
            "args": [

            "dependsOn":["make"]
        },
        {
            "label": "Build & Upload",
            "type": "shell",
            "command": "C:/Program Files/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI.exe",
            "args": [

                "port=SWD",
                "-hardRst"
            ]
        }
    ]
}

Step 2: config toolchain path

add your toolchain path to vscode user setting.json

example as below:

setting.json

{
    "cortex-debug.armToolchainPath": "C:/Program Files (x86)/GCC/gcc-arm/bin",
    "cortex-debug.stm32cubeprogrammer": "C:/Program Files/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin",
    "cortex-debug.gdbPath": "C:/Program Files (x86)/GCC/gcc-arm/bin/arm-none-eabi-gdb.exe",
    "cortex-debug.stlinkPath": "C:/Program Files/STMicroelectronics/STM32Cube/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.stlink-gdb-server.win32_1.6.0.202101291314/tools/bin/ST-LINK_gdbserver.exe"
}

Step 3: Build & Upload

press 'Ctrl+Shift+B' to engage build & upload

Step 4: Debug

press F5 to start debug mode
