Hello,

We don't have CubeMx RMII configuration for that specific part number but you can inspire from what it was implemented in NUCLEO-H743 as it uses RMII mode.

From its schematic

The LWIP example (unfortunately no ioc file available) where the Ethernet PHY is configured: 

https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/NUCLEO-H743ZI/Applications/LwIP/LwIP_HTTP_Server_Netconn_RTOS

You need to reflect the configuration in your CubeMx configuration.
