一：下载以下软件
1.mingw64
x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z
https://nchc.dl.sourceforge.net/project/mingw-w64/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/8.1.0/threads-posix/seh/x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z
将bin目录下的mingw32-make.exe改名成make.exe
2.msys64
msys2-x86_64-latest.tar.xz
https://mirrors.tuna.tsinghua.edu.cn/msys2/distrib/msys2-x86_64-latest.tar.xz
这里的make命令不支持中文路径，改名成任意名字
3.xPack GNU GCC 最新公版
xpack-riscv-none-elf-gcc
https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases/download/v12.1.0-2/xpack-riscv-none-elf-gcc-12.1.0-2-win32-x64.zip
4.OpenOCD
从MRS安装目录提取，linux用户可直接从http://file.mounriver.com/tools/MRS_Toolchain_Linux_x64_V1.40.tar.xz下载
二：分别解压上述软件到指定目录，并在系统环境变量添加上述软件bin目录
此电脑->属性->高级系统设置->环境变量->Path
三：编写Makefile
四：VScode安装Shortcut Menu Bar扩展
在"配置->扩展->Shortcut Menu Bar configuration"中为VScode增加四个Button，
执行命令分别为
workbench.action.tasks.build
workbench.action.tasks.runTask | clean
workbench.action.tasks.runTask | download
workbench.action.debug.start
依次是构建、清除、下载、调试
五：配置VScode json文件，相关文件路径请改为自己的安装目录
tasks.json

}
],
"preLaunchTask": "start-openocd",
"postDebugTask": "stop-openocd",
// "launchCompleteCommand": "None",
}
],
"version": "2.0.0"
}
六：注意
代码中所有__attribute__((interrupt("WCH-Interrupt-fast")))，需改为__attribute__((interrupt()))。参见http://m.**/bbs_thread-1155567-1-1.html
CFLAGS -march=rv32imac要改为-march=rv32imac_zicsr_zifencei
LDFLAGS 要增加-gdwarf-4，默认是dwarf-5调试有问题
GDB必须先执行命令set architecture riscv:rv32，否则连接Target会报错
Linux用户就不用下载mingw64和msys64了，只要设置好环境变量，gcc下载for linux的，其他基本一致
