编译

mkdir build
cd build
cmake .. -G"Unix Makefiles"
make -j

或者

cmake -Bbuild -G"Unix Makefiles"
cmake --build build

创建快捷指令：
删除 .vscode/tasks.json，

存储占用和生成 MAP

编译完成后，打印内存占用：在 cmake/gcc.cmake 中添加

-Wl,--gc-sections,--print-memory-usage

生成 map 文件，添加

-Wl,-Map=${PROJECT_NAME}.map,--cref

总体为：

SET(CMAKE_C_LINK_EXECUTABLE "\"${CMAKE_LINKER}\" ${CMAKE_EXE_LINKER_FLAGS} <OBJECTS> -Wl,--start-group ${RASC_CMAKE_EXE_LIBRARY_NAME_FLAGS} -Wl,--end-group -Wl,-Map=${PROJECT_NAME}.map,--cref -Wl,--gc-sections,--print-memory-usage")
SET(CMAKE_CXX_LINK_EXECUTABLE "\"${CMAKE_LINKER}\" ${CMAKE_EXE_LINKER_FLAGS} <OBJECTS> -Wl,--start-group ${RASC_CMAKE_EXE_LIBRARY_NAME_FLAGS} -Wl,--end-group -Wl,-Map=${PROJECT_NAME}.map,--cref -Wl,--gc-sections,--print-memory-usage")

显示图标

删除 .vscode/settings.json，删除前（左）对比删除后（右）

Git 忽略

build
*.d
*.sbd
.vscode/settings.json

pyocd

如果识别不到调试器，请尝试 python 3.10.10 安装 pyocd；
如果没有pyocd指令，记得将C:\Users\xxx\AppData\Roaming\Python\Python310\Scripts路径加入环境变量；

调试

如果不将工具链添加到环境路径，则需要在 launch.json 中指定：

"armToolchainPath": "D:/Applications/Toolchain/arm-gnu-toolchain-13.2.Rel1-mingw-w64-i686-arm-none-eabi/bin"

快捷

配置 tasks.json 使用快捷指令

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "prebuild",
            "type": "shell",
            "command": "cmake -Bbuild -G\"Unix Makefiles\""
        },
        {
            "label": "build",
            "type": "shell",
            "command": "cmake --build build -j",
            "problemMatcher": [],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}
