STM32H743ZIT6 LwIP - Ping Working in Example but Fails in My Own Project - Need Step-by-Step Help]

Hi everyone,

I am working with STM32H743ZIT6 and trying to implement basic Ethernet communication using LwIP. I downloaded the STM32CubeH7 package, and using the default LwIP example, I can successfully ping my STM32 board from my PC — no issues there.

However, when I try to replicate the same configuration in my own project, I cannot get ping to work. I suspect I am missing some configuration step or detail, even though I tried to match everything.

Details:

1. MCU: STM32H743ZIT6
2. Development Environment: STM32CubeIDE
3.LwIP Version: Provided with latest STM32CubeH7 package
4. PHY: LAN8742
5.Clock Configuration: HSE 25 MHz

, proper PLL setup
6.LwIP Example: LwIP_Ethernet example — works fine, I can ping
7.My Own Project: Same clock setup, same LwIP stack, but ping doesn't work

What is different between your project and the example project? Start there. Do a code diff. No code presented.

I use this example and It was successfully ping 

I want to learn how to config step by step please can I get any document .
