STM32H743 Ethernet FreeRTOS LwIP Ping Problem

[Muharrem]

Hi.

I'm trying a simple ping application with my board that contains the H743 microcontroller. I am following the instructions in Adam Berlinger's example. But I can't get ping. I connect my computer to my board via ethernet switch. My computer's IP is 192.168.2.5. But it can't reach to my board. When I try to send UDP packet, I can see the Ip adresses of target and destination(via WireShark software). But I can't see the "Hello UDP message!\n\r". IPs are manually setted. H7 board and computer connected via ethernet switch hub. I added a breakpoint to "void ETH_IRQHandler(void)". After the initial power-on, the system reaches the breakpoint twice even when there is no ping command on the Ethernet port. But when i send ping commands, nothing happens. I can reset LAN8742A PHY via GPIO. 

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  /* USER CODE BEGIN 2 */
  HAL_GPIO_WritePin(ETH_RESET_GPIO_Port, ETH_RESET_Pin, GPIO_PIN_RESET);
  HAL_Delay(50);
  HAL_GPIO_WritePin(ETH_RESET_GPIO_Port, ETH_RESET_Pin, GPIO_PIN_SET);
  HAL_Delay(100);
  /* USER CODE END 2 */

I changed my hardware and the problem solved. Topic can be closed.

@Muharrem  For the benefit of future readers who may find this while trying to solve a similar problem, it would be helpful if you would say what was wrong with your hardware, and how you changed it to fix the problem.

I have two hardware. One of them had solder issue. So i tried other one and it worked. The problem wasn't exactly spesific. I could see the PHY chip's REF_CLK. I could see the UDP package's IP adres but i can't see the data of package. They were all 00. I resolder the MCU of the faulty board over and over again. And then faulty card started to work correctly
