DM6467问题，ARM能连上，但是DSP连接不上是什么原因？

The target is stuck in Wait-in-Reset mode. The applied reset must be released before progressing.

Board Name: DM6467_xds560
Cpu Name: C6400PLUS_0
Abort: Close Code Composer Studio.
Retry: Try to connect to the target again.
Cancel: Remain disconnected from the target

麻烦帮忙看一下，谢谢~
