我是用的下边的JTAG_DPI GitHub - yaozhaosh/e200_opensource: The Ultra-Low Power RISC Core About (OpenOCD User’s Guide) 如何连结和调试 配置target.cfg文件 ##配置interface,bitbang和jtag_dpi相连,telnet_port是telnet和openocd相连 interface remote_bitbang ##注意,bitbang的host和port要和jtag_dpi设置为...
背景: 在之前相关文章的基础上,有两个多线程(hart)的cpu,每个cpu都有一个jtag(TAP)的debug module(DM),通过菊花链相连(测试了一共有2个TAP的情况),再用下riscv-debug-spec的图,途中红色圆圈,2个通过菊花链相连。调试的时候,只会调试某个cpu的某个hart,所以需要通过target.cfg来做jtag chain的声明,以及打开...

0b0111 1001 1110 0111 (0x79e7) MSB序列优先,我们需要使用LSB-first格式的0x7b 0x9e。 现在DP处于重置状态,我们可以发出DPIDR read命令来识别调试端口。为此,我们需要读取地址0x00处的DP寄存器。 下一步是启动调试域。规范文档的第2.4.5章告诉我们需要在DP的CTRL/STAT(地址0x4)寄存器中设置CDBGRSTREQ和CDBGR...
