我找到了關于debugportstop的描述:Power down and disconnect from target debug port.
Executed as last step during target disconnect unless another debugger connection to this port is active. The parent debugport is default debug port for this sequence.
This sequence must not contain access port register and target memory accesses.
根據這個描述,我感覺是我當時正在仿真,然后軟件死機以后我強制關掉軟件導致的,但是我不知道去哪里可以解決它,我嘗試過重裝keil和DSP的庫,也沒有解決這個問題
