  • Forum Post: RE: FlexRay - every third interrupt not generated

    Martin Zeman
    Hello Peter, thanks for your suggestions, however I'm not using the start of cycle interrupt but the received frame interrupt. The function clear_status_interrupt_register() indeed does nothing else but clear the whole SIR like this: void clear_status_interrupt_register(void){ frayREG->SIR_UN...

  • Forum Post: FlexRay - every third interrupt not generated

    Martin Zeman
    Hello, I'm handling interrupts generated by FlexRay controller at the start of a FR frame. My handler is set as FIQ. The problem is that for some reason every third FR cycle the interrupt is not generated. Sometimes it leaves out even more often. I have no other interrupts set as FIQ, so it should...
