stm32h7 ethernet not working

[tugbaozcan]

I made several changes in ethernetif.c 

pbuf_ref(p);
if (HAL_ETH_Transmit_IT(&heth, &TxConfig) == HAL_OK) {
	while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK)
	{
	}
	HAL_ETH_ReleaseTxPacket(&heth);
} else {
	pbuf_free(p);
}
//////////////////////////////////////
/* create a binary semaphore used for informing ethernetif of frame reception */
  RxPktSemaphore = osSemaphoreNew(1, 0, NULL);

  /* create a binary semaphore used for informing ethernetif of frame transmission */
  TxPktSemaphore = osSemaphoreNew(1, 0, NULL);

 I get vApplicationStackOverflowHook  and get connected and disconnect very fast What changes should i be doing to avoid that

Giving it more stack ... ?

I tried to increase stack size from 512 to 1024 . Overflow doesnt happen anymore but now no connection. If ı do get connected i get overflow

Please start from one of these ready examples: https://github.com/stm32-hotspot/STM32H7-LwIP-Examples

I am already using it as template The changes i did in ethernetif.c was recommended in other posts. Still dealing with overflow with increasing stack size
