Failing to recreate LWIP example code on NUCLEO-H743ZI2

[aa_hunter]

I am trying to create a simple UDP server using the NUCLEO-H743ZI2 board. I will port this to a similar microcontroller in the same family (STM32H750B) once I get it working. I am able to build the example code from this repository: 
https://github.com/stm32-hotspot/STM32H7-LwIP-Examples/tree/main/STM32H743_Nucleo_ETH

It successfully responds to pings and shows up in my router device list. I used:

STM32CubeIDE Version: 1.17.0 

STM32Cube FW_H7 Version 1.12.1.

Following the instructions in the README, I attempted to build the application from scratch on the NUCLEO board, but I haven't been able to get it to respond to a ping despite a few days of troubleshooting. 

Can someone tell me if there is something wrong with my configuration file?

Hello @aa_hunter, and welcome to ST community!

Attached is a project for the NUCLEO-H753. You can compare configurations and have a working project. Please make sure to add the proper linker file configuration to your project. Let me know if you need further assistance.

Best regards,

Thanks STackPointer64! I will compare against my config and let you know of any questions.

Hello @aa_hunter,

Have you been able to identify the issue causing your application to malfunction?

Thanks Stackpointer,

I haven't completed testing the solution you provided yet--I'm currently on travel and it could be a couple of weeks before I will have time to test it, but I will follow up here once I do.

Thanks!
