NUCLEO H753ZI LWIP Ethernet not working

[yc.2]

Hi,

I'm using the NUCLEO H753ZI board and trying to activate the Ethernet without success.

I can't ping the board from a PC which is connected to the board by a switch.

After configuring the ioc file by the CubeMX , creating a project and running by the Cube IDE the programs runs but nothing happens not even Led lighting

Attached my configuration (.ioc file),

I'm using the STM32Cube_FW_H7_V1.9.0 firmware.

following the steps in the below links, didn't yield a result.
