无需MRS，MC3172在多平台上的编译（基于梦程大佬的CMake模板）

梦程大佬提供了MC3172的CMake工程，网址是：https://github.com/dreamcmi/MC3172-CMake/

我的工作环境是macOS，之前使用赛昉科技RISC-V星光派时，用过赛昉的编译工具链，提供了Linux、Windows、macOS环境，非常好用。
该编译工具链，我后来使用CH32V307开发板时，发现也很好用。
这次感芯提供了一块MC3172的工程板，因为也是RISC-V的，所以试用了一下，也很好用，先分享给大家。

1. 下载赛昉RISC-V编译工具链：
网址是：https://github.com/sifive/freedom-tools/releases/
按照当前平台下载好对应的：
macOS环境：

https://static.dev.sifive.com/dev-tools/freedom-tools/v2020.12/riscv-openocd-0.10.0-2020.12.1-x86_64-w64-mingw32.zip

2. 下载CMake工程：
网址：https://github.com/dreamcmi/MC3172-CMake/

3. 设置工具链：
1) 解压上面的编译链工具，并找到 riscv64-unknown-elf-gcc 的目录，路径参考下面的：
/Users/HonestQiao/Projects/starfive/freedom-tools/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-apple-darwin/bin/riscv64-unknown-elf-gcc

上述路径中的/Users/HonestQiao/Projects/starfive/freedom-tools/，是我的macOS上的路径，请根据实际情况修改，下同

2）打开MC3172-CMake/CMakeLists.txt，修改其中工具链部分的配置：
macOS、Linux环境：具体路径请根据实际情况修改

# 工具链设置
set(TOOLPATH  /Users/HonestQiao/Projects/starfive/freedom-tools/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-apple-darwin/bin/riscv64-unknown-elf-)
set(CMAKE_C_COMPILER ${TOOLPATH}gcc)
set(CMAKE_CXX_COMPILER ${TOOLPATH}g++)
set(CMAKE_ASM_COMPILER ${TOOLPATH}gcc)
set(CMAKE_AR ${TOOLPATH}ar)
set(CMAKE_OBJCOPY ${TOOLPATH}objcopy)
set(CMAKE_OBJDUMP ${TOOLPATH}objdump)
set(SIZE ${TOOLPATH}size)

Windows环境：具体路径请根据实际情况修改

set(TOOLPATH  D:/0wch/toolchain/RISCVEmbeddedGCC/bin/riscv-none-embed-)
set(CMAKE_C_COMPILER ${TOOLPATH}gcc.exe)
set(CMAKE_CXX_COMPILER ${TOOLPATH}g++.exe)
set(CMAKE_ASM_COMPILER ${TOOLPATH}gcc.exe)
set(CMAKE_AR ${TOOLPATH}ar.exe)
set(CMAKE_OBJCOPY ${TOOLPATH}objcopy.exe)
set(CMAKE_OBJDUMP ${TOOLPATH}objdump.exe)
set(SIZE ${TOOLPATH}size.exe)

4. 编译：

cd MC3172-CMake
mkdir build
cd build
cmake ../CMakeLists.txt
make

执行make后，输出如下，表示成功：

[ 25%] Building C object CMakeFiles/mc3172-cmake.elf.dir/MC3172/thread_start.c.obj
[ 50%] Building C object CMakeFiles/mc3172-cmake.elf.dir/USER_CODE/GPIO_GPCOM_TIMER_Example.c.obj
[ 75%] Building C object CMakeFiles/mc3172-cmake.elf.dir/USER_CODE/main.c.obj

      DATA_SPACE:         256 B      61248 B      0.42%
[100%] Built target mc3172-cmake.elf

5. 下载：
使用感芯提供 GX_ISPTool 工具，下载MC3172-CMake/build/mc3172-cmake.hex 即可

现在，可以在当前环境中编译了，就可以用vscode进行开发了。
