BM3803板级支持包
1. 简介
BM3803是中国航天科技集团公司第九研究院第七七二研究所推出的基于SPARC V8内核的抗辐射32位处理器 包括如下硬件特性：
| 硬件 | 描述 |
|---|---|
| 芯片型号 | BM3803 |
| CPU | SPARC V8 |
| 主频 | 50 - 100MHz |
| SRAM | 2MB |
2. 编译说明
| 环境 | 说明 |
|---|---|
| PC操作系统 | Windows |
| 编译器 | sparc-gaisler-elf-gcc |
| 构建工具 | scons |
- 下载源码
git clone https://github.com/RT-Thread/rt-thread.git
- 下载编译工具和调试工具
下载对应的编译工具链 https://www.gaisler.com/index.php/downloads/compilers
下载对应的调试工具 https://www.gaisler.com/index.php/downloads/debug-tools
- 通过env配置工程
打开env工具，并切换到bsp/bm3803目录
输入menuconfig进行配置并保存
- 编译
配置rtconfig.py中的EXEC_PATH为对应的编译工具目录
输入scons进行编译
如果编译正确无误，会产生rtthread-bm3803.elf、rtthread.bin文件。可以使用rtthread-bm3803.elf进行调试。
- 调试
调试环境配置请参考 https://www.gaisler.com/eclipse/qsg_sw_ide.pdf
