[pupu_ji]

Hi ,all :

Use CMSIS-DAP download my project on demo board rt1170 getting error as follow:

But the demo SDK have will be no errors.

What are the possible reasons?

Please advise me how to solve this problem.

And debug configuration use default.

Is it possible that there is a problem with the project configuration?

Hello, thanks for the really helpful information, I reviewed the information maybe the MCU is in an unknown state, the error "ACK wire" sometimes means, the MCU is not halted by the Debugger.

Maybe this thread could help you.
