STM32H7/LWIP: IP Ping Error

[Gokul_Sarvanakumar_60]

Hi Community, 

I'm a new Developer/ for ST Microcontrollers, Now Im currently using STM32H723ZGT6 (NUCLEO - 144). Im currently working on ethernet (LWIP), the ping is not working for this code that i have generated . I have seen some youtube channels but I cant rectify and make the ping, I have tried all the possible things like , flash linker script , enabling ICache , Dcache , using MPU(Memory Protection Unit), change them to static ip for both board and my PC and So on . I have tried but I dont know whether my code or my implementation is correct or not . Can anybody help me with this ?..

I have attached the file thats my code and how project. pls have a look into that. 

Thank You.

I'm almost sure you didn't follow the exact steps described in the knowledge base article.

Do these ready, pre-configured examples work for you?

[Gokul_Sarvanakumar_60]

yes these pre- configured are perfectly working.  but my own code is not working 

[Gokul_Sarvanakumar_60]

can we do IP config without Free RTos , if possible pls share me a precofigured code , so that i can compare with my code and understand  the error

@Pavel A. @mƎALLEm , 

I'll followed all the steps in the article . Now if possible review and provide the Alterate solution . so that ican compare and do the coding

Hi @Gokul_Sarvanakumar_60 

Here you can find preconfigured LwIP examples without RTOS: LwIP_TCP_Echo_Server, LwIP_UDP_Echo_Server
