As my title says, i keep getting hard fault when i get interrupt.

Now when debugging, i see that interrupt happend, i get into the function to recieve rx content ( UART_Receive_IT ) but when i come to line :

      *huart->pRxBuffPtr++ = (uint8_t)(huart->Instance->RDR & (uint8_t)uhMask); 

i get a hard fault. 

I implemented uart example for my nucleo-l073rz to my existing project (also using HAL drivers) which uses RTOS.

Best regards,
