VSCode CMake Debug

Foreword

VSCode CMake Debug 嵌入式MCU有好几种方案

Cortex-Debug

OpenOCD

https://elmagnifico.tech/2023/07/22/Vllink-DapLink-Debug/

OpenOCD，需要专门的调试工具，ST-Link或者这里的VLink，支持CMSIS-DAP的

增加而一个build做为前置任务，然后启动openodcd

tasks.json

{// See https://go.microsoft.com/fwlink/?LinkId=733558// for the documentation about the tasks.json format"version": "2.0.0","tasks": [{"label": "build","type": "shell","command": "make","args": [],"group": "build"},{"label": "download","type": "shell","command": "openocd","args": ["-f","cmsis-dap.cfg","-f","stm32h7x.cfg","-c","program build/stm32h7_demo.elf verify reset exit"],"group": "build"}]
}

launch.json 主要给openocd输入调试配置

{"version": "0.2.0","configurations": [{"cwd": "${workspaceRoot}","executable": "./build/stm32h7_demo.elf","name": "Debug Microcontroller","request": "launch","type": "cortex-debug","showDevDebugOutput": false,"servertype": "openocd","configFiles": ["cmsis-dap.cfg","stm32h7x.cfg"]}]
}

JLink

顾名思义JLink需要配合JLink来使用

需要注意JLink的对应路径也需要在环境变量里，否则可能调用不到

JLinkGDBServerCL.exe -singlerun -nogui -if swd -port 50000 -swoport 50001 -telnetport 50002 -device STM32H743VI

在VSCode里新建一个launch，主要是svd和elf路径，device填正确就行了

{"version": "0.2.0","configurations": [{"name": "Cortex Debug-jlink","cwd": "${workspaceRoot}/","executable": "${workspaceFolder}/build/bin/demo.elf","request": "launch","type": "cortex-debug","servertype": "jlink","device": "STM32H743VI","interface": "swd","runToEntryPoint": "main","showDevDebugTimestamps": true,"svdFile": "${workspaceRoot}/config/STM32H743.svd",// "preLaunchTask": "build",// "postDebugTask": "run"}]
}

通过VSCode这种方式调用，启动非常慢，和SES对比就拉跨

Embedded Tools

之前用过的一个插件

https://elmagnifico.tech/2022/03/15/Embedded-Software-Development-VS-VSC/

本质上还是调用gdb然后配合openocd来实现调试的

        {"name": "Launch","type": "cppdbg","request": "launch","cwd": "${workspaceFolder}","program": "${workspaceFolder}/build/app/mxchip_azure_iot.elf","MIMode": "gdb","miDebuggerPath": "arm-none-eabi-gdb","miDebuggerServerAddress": "localhost:3333","debugServerPath": "openocd","debugServerArgs": "-f board/stm32f4discovery.cfg","serverStarted": "Listening on port .* for gdb connections","filterStderr": true,"stopAtConnect": true,"hardwareBreakpoints": {"require": true,"limit": 6},"preLaunchTask": "Flash","svdPath": "${workspaceFolder}/STM32F412.svd"}

Ozone

跳过VSCode，直接使用专业的Ozone来调试

https://elmagnifico.tech/2023/12/07/SES-Ozone-FreeRTOS/

配合我自己写的调用程序，很小30k，自动找到Ozone的路径，然后调用对应的调试文件，如果没有的话会自动新建一个

同样的烧写我也用了自己的程序去调用jlink完成烧写，比调用第三方插件可控性高多了

新建一个task，对应还有输入选择模板，否则一个配置要写一个task，太繁杂了

{"version": "2.0.0","tasks": [{"label": "Debug","type": "shell","command": "${workspaceFolder}/Ozone/flash.exe","args": ["--o","--path","${input:debugPath}"],"group": {"kind": "build","isDefault": false},"problemMatcher": [],"options": {"env": {"DEBUG_PATH": "${input:debugPath}"}}}],"inputs": [{"id": "debugPath","type": "pickString","description": "Select the debug configuration","options": ["${workspaceFolder}/Ozone/test.jdebug","${workspaceFolder}/Ozone/test2.jdebug","${workspaceFolder}/Ozone/test3.jdebug","${workspaceFolder}/Ozone/test4.jdebug",],"default": "${workspaceFolder}/Ozone/test.jdebug"}      ]
}

Summary

总体来说VSCode的调试不是很好用，还是原生的更好一些。

总感觉VSCode这里给的接口实在是太多了，选择太多了，但是每个选择其实做的都一般，没做到极致的水平

这些插件更像是一个整合工具，然后再接入另外一个整合工具，层层套娃，最后糊了一个勉强能用的东西
