Using vs code to debug ARM-CortexM

This document describes how to use vs code to debug arm-cortexM3 (STM32F207) in my project.

Environement:

VS code

VS code plug-in : Cortex-Debug

CMAKE is not mandatory.

install software:

cmake-3.18.2-win64-x64.msi

gcc-arm-none-eabi-9-2020-q2-update-win32.exe

ninjia : using ninjia as the build shell

using hareware Jlinker, you shall install the software to support jlinker.

firstly, you have to make sure your project is successful built and generate the elf file. I will not describe it here.

 

Configurion

setting.json has to define the  armToolchainPath and  JLinkGDBServerPath.

    "cortex-debug.armToolchainPath": "C:/Program Files (x86)/GNU Arm Embedded Toolchain/9 2020-q2-update/bin/",

    "cortex-debug.JLinkGDBServerPath": "C:/Program Files (x86)/SEGGER/JLink_V614b/JLinkGDBServer.exe"

 

laungh.json as below

{

    "version": "0.2.0",

    "configurations": [

        {

            "type": "cortex-debug",

            "request": "launch",

            "servertype": "jlink",

            "cwd": "${workspaceRoot}",

            "executable": "./BuildARM/out/bin/DemoPanel.elf",

            "name": "Debug (J-Link)",

            "device": "STM32F207ZE",

            "interface": "jtag",

            "ipAddress": null,

            "serialNumber": null,

        }

    ]
