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
  1. 下载源码
git clone https://github.com/RT-Thread/rt-thread.git
  1. 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
  1. 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
  1. 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。

  1. 调试
调试环境配置请参考 https://www.gaisler.com/eclipse/qsg_sw_ide.pdf
