Assistance with LAN LWIP Configuration on STM32H7S7DK Development Board (RMII)

[VijayKushwah]

Hi ST Community,

I am currently working with the STM32H7S7DK development board and am configuring the LAN LWIP stack using RMII for Ethernet communication. However, when I run the code, the system encounters a HardFault.

I am using STM32CubeMX for code configuration and STM32CubeIDE as the debugging environment. I would appreciate any assistance or guidance regarding this issue. If anyone has a basic project setup for configuring LAN LWIP with RMII on the STM32H7S7DK, it would be extremely helpful if you could share it with me. This would allow me to better understand what might be causing the HardFault.

Thank you in advance for your help!

Best regards,

Dear ST Support Team,

Thank you for your prompt response and assistance regarding my inquiry. I successfully used the demo project you provided, and everything works as expected. However, when I create a new project using STM32CubeMX, the project does not work as intended.

The issue seems to be that although my configuration appears fine, the IP is not being correctly configured in the newly created project. 

To assist in diagnosing the issue, I have attached some screenshots of my project configuration. I hope these will help clarify the problem.

I would greatly appreciate your assistance in resolving this, and I look forward to your guidance on the next steps.

Best regards,
