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!
