Hello, S324324 can work normally during simulation, but when running offline, there may be a CM7_1 core hard fault. Could you please help identify the problem? Attached is a screenshot of the hard fault when attached.

Hi @jack_22,

You can find more about the fault exception by following these documents/examples:

If it works with the debugger, it could be because the algorithm the debugger uses enables peripheral clocks and initializes all the volatile memories, etc. Without the debugger, the application cores must do that.

 

Regards,

Daniel
