Hello @lhwa .1 ,

I advise you to start by configuring the LWIP. For that I recommend you to follow the steps shared in this FAQ How do I create a project for STM32H7 with Ethernet and LwIP stack working?.

The Goal of this example is to:

• Configure project in STM32CubeMX for STM32H750-Discovery
• Configure FreeRTOS and LwIP middlewares correctly
• Send UDP message periodically (optional)

I hope this help you!

Thank you.
