1. 准备

需要瑞萨仓库中的两个软件：

1. MDK_Device_Packs.zip
2. setup_fsp_rasc.exe(RA Smart Configurator)

交叉编译工具链：

1. gcc
2. cmake

---

2. 安装

2.1. 安装瑞萨软件包

MDK_Device_Packs_v5.2.0.zip
setup_fsp_v5_2_0_rasc_v2024-01.1.exe

安装 setup_fsp_rasc.exe(RA Smart Configurator)

2.2. 安装编译器

Arm GNU Toolchain Downloads – Arm Developer
下载最新版本：arm-gnu-toolchain-13.2.rel1-mingw-w64-i686-arm-none-eabi.zip

下载后解压，把解压路径添加到环境变量。

在终端中执行指令，查看 gcc 的版本信息：

$ arm-none-eabi-gcc -v
Using built-in specs.
COLLECT_GCC=D:\Applications\Toolchain\arm-gnu-toolchain-13.2.Rel1-mingw-w64-i686-arm-none-eabi\bin\arm-none-eabi-gcc.exe
COLLECT_LTO_WRAPPER=D:/Applications/Toolchain/arm-gnu-toolchain-13.2.Rel1-mingw-w64-i686-arm-none-eabi/bin/../libexec/gcc/arm-none-eabi/13.2.1/lto-wrapper.exe
Target: arm-none-eabi
Configured with: /data/jenkins/workspace/GNU-toolchain/arm-13/src/gcc/configure --target=arm-none-eabi --prefix=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/install --with-gmp=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/host-tools --with-mpfr=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/host-tools --with-mpc=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/host-tools --with-isl=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/host-tools --disable-shared --disable-nls --disable-threads --disable-tls --enable-checking=release --enable-languages=c,c++,fortran --with-newlib --with-gnu-as --with-headers=yes --with-gnu-ld --with-native-system-header-dir=/include --with-sysroot=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/install/arm-none-eabi --with-multilib-list=aprofile,rmprofile --with-libiconv-prefix=/data/jenkins/workspace/GNU-toolchain/arm-13/build-mingw-arm-none-eabi/host-tools --host=i686-w64-mingw32 --with-pkgversion='Arm GNU Toolchain 13.2.rel1 (Build arm-13.7)' --with-bugurl=https://bugs.linaro.org/
Thread model: single
Supported LTO compression algorithms: zlib
gcc version 13.2.1 20231009 (Arm GNU Toolchain 13.2.rel1 (Build arm-13.7))

2.3. 安装 cmake

https://cmake.org/download/

下载后解压，把解压路径添加到环境变量。

在终端中执行指令，查看 cmake 的版本信息：

$ cmake --version
cmake version 3.28.4CMake suite maintained and supported by Kitware (kitware.com/cmake).

2.4. 安装 openocd

https://github.com/openocd-org/openocd/releases

下载解压后，将解压路径添加到环境变量中。

在终端中执行指令，查看 openocd 的版本信息：

$ openocd --version
Open On-Chip Debugger 0.12.0 (2023-01-14-23:37)
Licensed under GNU GPL v2
For bug reports, readhttp://openocd.org/doc/doxygen/bugs.html

2.5. 安装 ninja

ninja 和 make 都是构建系统工具，它们通常作为后端，被 cmake 生成和使用，相比之下 ninja 具有更好的性能和更专注于构建速度。

https://github.com/ninja-build/ninja/releases

下载解压后，将解压路径添加到环境变量。

在终端中执行命令，查看 ninja 版本信息：

$ ninja --version
1.11.1

2.6. 安装 make

https://gnuwin32.sourceforge.net/packages/make.htm

下载安装后，需要将安装路径添加到环境变量中。

在终端中执行命令，查看 make 版本信息：

$ make --version

3. 生成初始代码

打开 rasc(RA Smart Configurator)

RAFA6M3A H 3 C FB

1. H：2MB
2. FB：144引脚
   

4. 修改 cmake 脚本

修改顶层 CMakeLists.txt

5. 调试准备
