OpenOCD之J-Link下载

1.下载USB Dirver Tool.exe，选择J-Link dirver，替换成WinUSB驱动。（⭐USB Dirver Tool工具可将J-Link从WinUSB驱动恢复为默认驱动⭐）

下载方式
①官方网址：https://visualgdb.com/UsbDriverTool/
②笔者的CSDN链接：https://download.csdn.net/download/ZZLLLLLLZ/89902055

在这里插入图片描述
2.打开安装好OpenOCD路径的interface接口脚本文件夹，比如笔者安装OpenOCD路径的interface接口脚本文件夹如下：

D:\Software\embedded_dev_tools\xpack-openocd-0.12.0-3\openocd\scripts\interface

3.复制新的一份jlink.cfg，并重命名为jlink-swd.cfg。

4.在jlink-swd.cfg文件的 adapter driver jlink 语句下方添加 transport select swd，如下图所示：

5.将task.json中的 -f interface处后面的接口文件名修改成上述的jlink-swd.cfg；

        {
            "type": "shell",
            "label": "flash with J-link",
            "command": "openocd",
            "args": [
                "-f",
                "interface/jlink-swd.cfg", //D:\Software\embedded_dev_tools\xpack-openocd-0.12.0-3\openocd\scripts\interface
                "-f",
                "target/stm32f4x.cfg", //D:\Software\embedded_dev_tools\xpack-openocd-0.12.0-3\openocd\scripts\target
                "-c",
                // "program build/F401CCU6_demo.elf verify reset exit"
                "program build/${workspaceRootFolderName}.elf verify reset", //将工程根目录名称作为可执行文件名称
                "-c",
                "reset run",
                // "-c",
                // "shutdown",
                "-c",
                "exit"
            ], /*command+args相当于主命令+子命令，也就是openocd -f interface/stlink-v2.cfg -f target/stm32f1x.cfg -c "program build/F401CCU6_demo.elf verify reset exit"的效果*/
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "dependsOn": [ //每次执行这个任务，会先build任务，这便是所谓的依赖。
                "build"
            ]
        }

同理将launch.json中的J-link调试段的 interface 处后面的接口文件名修改成上述的jlink-swd.cfg。
