openJTAG学习笔记一

安装软件
光盘Windows\install目录下的
01.OpenOCD with GUI setup.exe
02.yagarto-bu-2.18_gcc-4.2.2-c-c++_nl-1.16.0_gi-6.8.50_20080408.exe
03.yagarto-tools-20070303-setup.exe
jre7




使用eclipse调试led程序
1 导入光盘示例放入D:\c_porjects
2 新建工程
3 编译
4 调试
安装zylin
help-->install new software
http://opensource.zylin.com/zylincdt


１点击debug configurations-->c zylin embedded debug (native)
２debuggers标签的GDB command file设置为；
　　　　　　　D:\c_porjects\6410\s3c6410_gdb.init
３commands设置
　　load
　　break main
　　c


openJTAG烧写第一个程序
1 进入应用目录D:\c_porjects\6410\1th_led,执行make命令编译程序
3 打开openODC程序指定开发板型号,设定工作目录,然后点击connect
  此时可能有很多警告提示，先设为SD卡启动（不需插SD卡），再点connect,正常后直接
  带电拔到NAND启动
4 点击tellnet,执行以下命令
