TE6410中openoc.CFG配置及调试

首先安装openocd,具体步骤请参考我前面的文章。

然后就是配置openocd,以下是我的配置,仅供参考,也希望更多的人能够共同成长,一同分享:

将配置文件复制到你的工作目录下,就是你要load文件的目录

之后:

1、打开minicom,

2、打开开发板,启动uboot,然后在minicom终端中迅速敲任意键

3、进入有配置文件的目录,使用命令openocd,即可启动openocd

4、打开另一个终端2,使用命令telnet localhost 4444

5、在终端2中,使用load_image led.bin 0X50008000

6、在终端2中使用命令resume 0x50008000即可

注意第5 、6步,load文件可以使bin、elf、ihex、s19,若要使用调试功能,就要使用命令step命令
