Hello @firmwareteam

The project building successfully and debugging failed, is this situation? If so, what type debugger did you use?

Hello @firmwareteam

Your case is very special. If the above information does not appear, it means the debugger did not find it. I have not been able to reproduce your case, so it is hard to judge what is the reason. Do you have MCU-LINK PRO? How about a different debugger and try again?
