Ethernet Based Application in H755ZI-Q board using LwIP -TCP communication particularly for RMII support

[Mahesh07]

Hello community! We are trying to develop an application based on Ethernet using  LwIP stack in STM32H755ZI-Q nucleo board which supports only RMII mode of configuration. We need a communication to be based on TCP protocol. For this we need some solutions for how to enable the required modules and functions in generated files and please suggest us the example files to transmit and receive the data via ethernet from board to board, board to PC or Board to PLC (Especially the functions and how to configure and pass the function parameters with data).

Wanna set up Ethernet with LwIP on the STM32H755ZI-Q, my recommendations are:

1. Enable Ethernet (RMII) and LwIP in CubeMX.
2. Configure LwIP for TCP and generate code.
3. Use MX_LWIP_Init() to initialize.
4. Reference STM32CubeH7 examples like lwip_tcpecho.
