Implementing Ethernet IAP in STM32F767ZI Nucleo Board

[Renato Valentim]

I'm looking to implement Ethernet IAP with the STM32F767ZI Nucleo Board. The only example I have is for the STM32F769I_EVAL board where the INT pin from the phy is connected to the microcontroller. There is no such pin connected to the MCU in the Nucleo board. The code I have has this:

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
  /* Get the IT status register value */
  if(BSP_IO_ITGetStatus(MII_INT_PIN))
  {
    ethernetif_set_link(&gnetif);
  }
  BSP_IO_ITClear();
}

Is this absolutely needed for IAP? If so, how can I somehow replicate this behavior with the NUCLEO board?

Thanks
