"I am currently working on implementing Ethernet communication using a NUCLEO-H753 board.
As a first step, I attempted to perform a ping test. I followed the official tutorial videos provided by STMicroelectronics step-by-step, but unfortunately, I am not getting the expected results (the ping is failing).
I would appreciate any guidance or advice on what might be causing this issue or which specific configurations I should double-check."
"Let me share my CubeMX configuration with you first so we can review the setup."
1. System Core - CORTEX_M7
2. Connectivity - ETH
3. LwIP
4. Clock
I will also share the modified source code with you.

I am receiving these messages as shown in the screenshot,
and I'm reached out because I’m not sure what I might be missing in the configuration.
As you can see, I am getting 'Destination host unreachable' errors.
I would appreciate it if you could help me identify what's wrong.
Edited to apply proper source code formatting - please see How to insert source code for future reference.
