k66 ethernet rx interrupt

Teensy 3.6 ethernet rx interrupt

Hello
I have trouble getting the k66 ethernet rx interrupt to trigger.

i am activating the interrupt and interrupt mask:

ENET_EIR = ENET_EIR_RXF;
ENET_EIR = ENET_EIR_RXB;
ENET_EIMR = ENET_EIRM_RXF | ENET_EIRM_RXB;

the ring buffer is set to allow interrupt:

for (int i=0; i < RXSIZE; i++) {
    rx_ring[i].flags.all = 0x8000; // empty flag
    rx_ring[i].moreflags.all = 0x80; // set Interrupt true
    rx_ring[i].buffer = rxbufs + i * 128;
}

the interrupt function is set:

void rxIRQ(void){
  Serial.println("........Interrupt........");
  interruptFlag++;
  ENET_EIR = ENET_EIR_RXF;
  ENET_EIR = ENET_EIR_RXB;
}

and the interrupt vector i activated:

attachInterruptVector(IRQ_ENET_RX, rxIRQ);
NVIC_IS_ACTIVE(IRQ_ENET_RX);
NVIC_ENABLE_IRQ(IRQ_ENET_RX);
__enable_irq();

this triggers no interrupts....

NVIC_TRIGGER_IRQ(IRQ_ENET_RX); will trigger a interrupt

and replacing IRQ_ENET_RX with IRQ_ENET_ERROR
you get a interrupt befor every mdio_read

i have rx and tx interrupts enabled in the following sketch (i just count packets in and out)

Thank you.

i had the flag wrong
rx_ring.moreflags.all = 0x80;
should be
rx_ring.moreflags.all = 0x8000;
