Hi Haibo Yang,

Please tell me what the board and the code you are using? Is the official board?

Please also check the MDK configrations:

Whether in Utilities also have he debugger configurations?

In this picture:

Please select the lower max clock and try again.

If you still have problem, please tell me the board, the code and the MDK version which you are using, then I will try it on my side.

Have a great day,
Kerry
