MRS?IDE?基于Eclipse,?代码体验与同出一处的STM32CubeIDE基本一样,?相比Keil来说,?体验好很多了，但是与VScode，?Clion体验还是差了不少，看了编译流程，?是使用make，?因此使用Cmake生成Make是没问题的。
准备工具：CMake，RISC-V Embedded GCC，make
其中CMake，?make比较好找。在经过我试验之后发现，?WCH使用的RISC-V编译器与通用的RISC-V编译器不太一样，?有些地方是修改过了，?在使用xpack-riscv-none-elf-gcc-12.1.0-2编译时 core-riscv.c?文件内大量的汇编语言是报错的,?应该使用特有指令。所以只能使用MRS安装路径下提供的RISC-V Embedded GCC，?
CMakeLists.txt与使用STM32的时候是差不多的，只需要修改少量地方，?一个是指定编译器平台，?一个是编译参数和链接参数
具体可以参考以下:

?设置Clion工具链。
环境脚本内容需要修改你自己的路径：
set?PATH=path\to\your\MounRiver_Studio\toolchain\RISC-V?Embedded?GCC\bin;%PATH%
? ? ? ?选择工具链
? ?接下来就可以编译了
和MRS编译相比:
? ?2.?设置VSCode
? ?2.1.安装CMake,?CMake?Tool,?C/C++插件
? 2.2.?配置CMake,?主要配置CMake环境变量,?编译平台,?该配置文件需要在工程根目录下下新建 .vscode 文件夹,?在 .vscode
?文件夹下新建 settings.json?,?内容参考如下,?需要根据实际情况修改:

? ?另外还需配置C/C++插件,?主要是? intelliSenseMode?和?configurationProvider
"configurationProvider":?"ms-vscode.cmake-tools", "intelliSenseMode":?"gcc-x86"
? ?接下配置CMake,?编译平台在CMakeLists.txt里指定了,?路径环境变量在?settings.json?里? cmake.environment?指定了。
? ?VSCode底边栏应该是这样的：
在左边栏,?点击Cmake图标,?再点击配置项目
接下来编译即可,?点击底边栏的 Build,?等待完成，?无错误的话，?应该输出如下：
示例工程:
使用VSCode,?Clion?均无法调试下载,?OpenOCD是WCH修改编译过才能识别WLink,?原生OpenOCD是无法识别WLink的,?期待WCH进一步开放相关资料
