### 3. 使用说明
### 3. scons构建系统
#### 3.1 FPGA 工程设计
通过加入`rtconfig.py`，`SConstruct`，`SConscript`文件，可支持scons构建系统，可以输入`scons`调用env工具中包含的arm-gcc编译器构建工程，支持以下scons命令：
- `scons`：使用arm-gcc编译BSP
- `scons -c`：清除执行 scons 时生成的临时文件和目标文件。
- `scons --target=mdk4`：重新生成Keil MDK4环境下的工程。
- `scons --target=mdk5`：重新生成Keil MDK5环境下的工程。
- `scons --dist`：打包BSP工程，包括RT-Thread源码及BSP相关工程文件。
添加Kconfig文件，用于生成rtconfig.h。
### 4. 使用说明
#### 4.1 FPGA 工程设计
FPGA 部分使用 SmartDesign 图形化设计，不需要写 HDL 代码，时钟来自外部 50M 晶体输入，PLL 倍频 100M 提供给 MCU 使用，顶层配置如下图所示：
![](figures/top_sd.jpg)
MSS 部分仅使用到了GPIO 和UART，GPIO_0和GPIO_1配置成输出输出模式用于驱动LED，GPIO_2和GPIO_3配置成输入模式，用于读取按键输入。
MSS 部分仅使用到了GPIO 和UART，GPIO_0配置成输出输出模式用于驱动LED。
配置完成的 FPGA 工程文件下载：[sf2_fpga_prj.rar](https://wcc-blog.oss-cn-beijing.aliyuncs.com/Libero/RT-Thread/sf2_fpga_prj.rar)
#### 3.2 ARM 程序设计
#### 4.2 ARM 程序设计
ARM 程序使用 Keil MDK 5.26 开发，需要安装 M2S 系列芯片支持包：[Microsemi.M2Sxxx.1.0.64.pack](http://www.actel-ip.com/repositories/CMSIS-Pack/Microsemi.M2Sxxx.1.0.64.pack)
