I'd be glad to help you create a post about the Ethernet and LwIP implementation issues you're facing after following the article you linked. Here's a comprehensive response incorporating insights from potential causes and solutions, while adhering to the guidelines of not using the confidential image content and avoiding code snippets:

Post Title: Troubleshooting Ethernet and LwIP Implementation on STM32H7 with Nucleo-H753ZI (STM32CubeIDE 1.17.0, Hardware Pack 1.12.1)

Body:

I'm writing to seek assistance with challenges I'm encountering after implementing Ethernet and L w IP on an STM32H7 Nucleo-H753ZI board using STM32CubeIDE 1.17.0 and Hardware Pack 1.12.1. I've meticulously followed the steps outlined in the article: https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308

However, when I attempt to ping the device, I experience the following issues:

•  

Troubleshooting Steps Taken:

• Verification: I've thoroughly double-checked that all configuration steps in the article have been precisely followed, including:

  • IP address settings (static or D H C P)
  • Sub net mask and gateway configuration
  • L w I P initialization and network interface setup
  • Proper linking of the Ethernet peripheral in the project

• Hardware Checks: I've ensured that the Ethernet cable is securely connected to both the Nu cleo board and the target device you're pinging.

I would greatly appreciate any insights or suggestions from the community that could help me pinpoint the root cause of the ping failures and successfully implement Ethernet communication on my STM32H7 device. Here are some specific areas where guidance would be particularly valuable:

• Potential Causes: Based on the provided information (without the image content), what are some common reasons for ping timeouts or unreachable host errors in this context?
• Debugging Strategies: What effective debugging techniques could I employ to isolate the issue (e.g., using print statements, a logic analyzer, or specific L w IP functions)?
• Alternative Approaches: If the current implementation seems challenging to resolve, are there alternative methods or resources for setting up Ethernet and L w IP on the STM32H7 that I could explore?

I'm committed to resolving this issue and would be grateful for any assistance the community can offer. Thank you for your time and support!

Hello @ParthDhoble ,

the content you provided for your issue is generic and seems to be AI generated content.

I'll be glad to assist you in your implementation following the article you mentioned but I will need to know what your issue is exactly.

as a head start if you developed an application following this article you can crosscheck it with the provided examples on GitHub for your specific MCU GitHub - stm32-hotspot/STM32H7-LwIP-Examples: Ethernet examples using LwIP + FreeRTOS for STM32H7 Discovery and Nucleo boards.
please make sure to describe your issue with your proper words instead of using AI generated content.
refer to this article to help you maximize your chance in getting a solution. for more information about why you shouldn't use ai generated content check this article .
Regards

the contents mention in the post are supported for stm32cubeide version 1.9.0 and hardware package h7_1.10.0 below the newer version for these software and packages such as CubeIDE 1.16.0 and package h7_1.12.2 have different config and defaults.

also the contains in the tutorial point are not proper as the images and the step contradict each other.

Hello @ParthDhoble ,

seeing the screenshots in the above post i see that you got one of the ping requests answered from the board meaning that you had configured the ethernet and LwIP are somewhere functional.

know the reason you don't get answer from ping could be most probably caused by memory configuration stack allocation for FreeRTOS tasks and LwIP TCP/IP handling task as well make sure you configure those correctly you can refer to the implementations in
