OpenOCD之J-Link下载

NOTE：此篇文章由笔者的 VSCode编辑+GCC for ARM交叉编译工具链+Makefile构建+OpenOCD调试（基于STM32的标准库）派生而来。

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⭐）

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

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.打开jlink-swd.cfg文件，在jlink-swd.cfg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，如下图所示：

task.json文件内容：

 //J-link方式下载{"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，如下图所示：

launch.json文件内容：

//调试脚本

}
