AElta.1 · ‎2022-10-07

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:

Reply from 192.168.1.37: Destination host unreachable.

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.
