前提条件

安装Cortex-Debug插件
在这里插入图片描述
安装OpenOCD
安装JLink驱动

配置调试

通过vscode左侧的调试和运行按钮 在这里插入图片描述选择生成launch文件

配置JLink使用`JLinkGDB`进行调试

将如下内容添加到launch文件合适的位置

{
            "name": "Cortex Debug-jlink",
            "cwd": "${workspaceRoot}/",
            "executable": "${workspaceFolder}/build/${workspaceFolderBasename}.elf",
            "request": "launch",
            "type": "cortex-debug",
            "servertype": "jlink", //要选择的GDB server
            "device": "STM32F405RG",
            "interface": "swd",
            "runToEntryPoint": "main",
            "showDevDebugTimestamps": true,
            // "svdFile": "${workspaceRoot}/STM32F103.svd",
            // "preLaunchTask": "build",
            // "postDebugTask": "run"
        }

修改该内容使之适配自己的工程：

executable参数为要执行的目标文件
devices为当前使用的mcu型号
svdFile参数指定对应mcu的.svd文件位置，用于调试的时候查看寄存器的内容。
preLaunchTask（调试前执行任务）和postDebugTask（调试结束后执行任务）根据需要添加，实际指的是task.json文件中定义好的任务。

配置stlink使用openOCD进行调试

将如下内容复制到对应的launch文件中

{
            "name": "Cortex Debug-stlink",
            "cwd": "${workspaceRoot}/",
            "executable": "${workspaceFolder}/build/${workspaceFolderBasename}.elf",
            "request": "launch",
            "type": "cortex-debug",
            "servertype": "openocd", //要选择的GDB server
            "device": "STM32F405RG", //
            "interface": "swd",
            "configFiles": [
                // "${workspaceRoot}/openocd.cfg"
                "interface/stlink-v2.cfg",
                "target/stm32f4x.cfg",
            ],
            "runToEntryPoint": "main",
            "showDevDebugTimestamps": true,
            // "svdFile": "${workspaceRoot}/STM32F103.svd",
            "preLaunchTask": "build",
            "postDebugTask": "run"
        }

需要修改的位置和上面基本一致。
