FreeRtos Porting with Nabto

Access violation at address 0 means something tried to access address 0x00000000 (NULL). In this case something tried to execute something at that address, which I would guess means (perhaps) you tried to execute an uninitialised function pointer. This is a C coding/debugging question though, not a FreeRTOS question.
