Issuing a reset by pressing the mechanical reset button on the pcb causes a MemManage_Handler fault in some situations.

Root cause unclear. Could cause a potential stability problem if resets are happening during power on due to a instable power supply.

Observed with commit: ee8bd2c795f60d2bd8ec1ff357ee1f9e03b51065

Seems to be related to the sd card and writing to it.

Also sometimes happens sporadically when debugging.

Max, von welcher Platform redest du ? Utility-Board ? Sensor ? AD57 ?

Not observed in the field so assumed this is a debugging issue. There will be no further investigations.
