Problem using ethernet connection in Nucleo-h743zi2

[AElta.1]

hi

I am using Nucleo-H743ZI2 for Ethernet :

Ethernet RMII:

First TxDescribter Address: 0x30000200.

First RxDescribter Address: 0x30000000.

Rx Buffers Length: 1536.

CortexM7 setup:

LWIP:

key options:

LAN : Platform

add to Flash.id:

 .lwip_sec (NOLOAD) :

 {

  . = ABSOLUTE(0x30000000);

  *(.RxDecripSection) 

   

  . = ABSOLUTE(0x30000200);

  *(.TxDecripSection)

   

  . = ABSOLUTE(0x30000400);

  *(.Rx_PoolSection)  

 } >RAM_D2

add in main.c:

while (1)
 {
 /* USER CODE END WHILE */
	 MX_LWIP_Process();
	 	 HAL_Delay(1);
 /* USER CODE BEGIN 3 */
 }
 /* USER CODE END 3 */
}

but he when I ping the address I get :

ping 192.168.1.10

Pinging 192.168.1.10 with 32 bytes of data:

and I also tried the examples in :

https://github.com/stm32-hotspot/STM32H7-LwIP-Examples

but does not work still. same ping issue

I also followed guide in :

https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working

but does not work still. same ping issue

Please always start from a ready example for this Nucleo, in the Cube software package or from github.

Do not use cube-generated stuff until you have a ready example working (whatever this means) as a reference.

Also, use a private ethernet network, avoid connecting the board to office network or internet while debugging.
