For some reason the software ends up executing Dummy_Handler(). An enabled interrupt without interrupt handler could be a cause, but all the interrupts enabled do have an interrupt handler.
Has anyone an idea how to find out the cause of it?

I think it is caused by the flash read wait state setting. The uC is running on 48MHz. The uC crashes with the wait state set to 2, while this should be ok for a 48MHz clock on 3.3V. When the wait state is set to 3 everything seems ok. Does anyone have some experience with these kind of issues?
