Hi, many times during my code running, my program stops running for unknown reasons (many times where it implies writing to the debug USART).
I noticed that I goes everytime inside the "Dummy_Handler", inside "startup_saml21.c", which appears to be an exception handler.
My questions are : how to properly manage exceptions ? Should I write debug stuff inside the Dummy Handler ? Can I use the printf inside it ? Should I write it inside this file or is there another good way to do it ?
