TMS320F28377D: Test connection成功，connect target失败

ccs10, 28377d，XDS200仿真器，Test connection成功，connect target失败，报错信息如下：

C28xx_CPU1: Trouble Reading Register ST1: (Error -1041 @ 0x5F453) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation.

断电，拔掉仿真器重连几次都这样

Green Deng：

你好，请问是自己制作的板子连接仿真器出现这个问题吗？之前有正常连接过吗？
