Problems with ethernet on SMT32F429ZIT6

[PabloD9026]

Hi, I am having problems connecting my f429 board (nucleo 144) through ethernet with TCP. I followed several threads that i lost the link to, but here are my settings.

 

and of course the LWIP configuration (everything not shown was left by default)

i al turned on LWIP_BROADCAST_PING and LWIP_MULTICAST_PING

IPv6 and HTTPD are disabled

and here for the PHY i tried with both, and none worked.

also increased the heap size

In the code, on the main while(1) function, i have the: MX_LWIP_Process()

The problem is that i try to ping the board, and i get timeout, never an answer.

Can anyone se any problems or has any idea why?

Hello @PabloD9026 ,

Have you Checked this FAQ: How do I create a project for STM32H7 with Ethernet and LwIP stack working?

Also, I advise you to start with an available LwIP_HTTP_Server_Netconn_RTOS example. This application guides STM32Cube HAL API users to run a http server application based on Netconn API of LwIP TCP/IP stack.

This example may be help you to configure your own project. 

Thank you.

I have one more question, in the examples you ve sent it was written that the STM32 board has to be connected with a crossover ethernet cable or through a router. 

My question is, is this true? and can i use an ethernet-switch instead of a router?, if not, is there any work-around? for examples changing some pins on the board.

Hi @PabloD9026,

Yes, you can use an Ethernet-switch.

Thank you for your contribution in STCommunity.
