ARM裸板调试之JTAG调试体验
2022-07-06 17:21:00 【陈 洪 伟】
先用一个leds.bin的例子看一下JTAG的使用。
使用openOCD GUI软件，
点connect会出现右边的信息，
然后点击telnet，会出现 telnet窗口
win7操作系统可能没法点telnet，那就用如下命令，效果是一样的，也会出现telnet窗口。
然后在里面可以用各种命令了
用ultraedit吧leds.bin打开看一下，0地址的确是e3a00453.
再试一下打断点，我们想在wait这里打断点
看一下反汇编，wait的地址在哪里
然后看一下bp命令
下面试一下软件断点，我们从反汇编文件中可以看到6c这里现在的值是ebffffe9.
