Ethernet connectivity issue STM32H7

[Aarra.1]

Hello everyone,

I have been working with stm32h747xih6 MCU for a while now.

I'm trying to establish ethernet communication with the MCU.

  if (netif_is_link_up(&gnetif))
  {
    /* When the netif is fully configured this function must be called */
    netif_set_up(&gnetif);
  }
  else
  {
    /* When the netif link is down this function must be called */
    netif_set_down(&gnetif);
  }

My code always goes to the else condition in the above snippet of the code.

I have attached my .IOC file below for reference.

At times when i do arp -a from command terminal my device IP comes on the command prompt but when I try to ping the connection is lost.

Kindly help me out with this issue

Hello @Aarra.1​ ,

I advise you, when you configurated the ethernet project, to get inspired form the steps described in this FAQ: How to create project for STM32H7 with Ethernet and LwIP stack working. This FAQ will help you to configure your project in STM32CubeMX .

Also, you can get started with the example provided here STM32H7-LwIP-Examples.

I hope this help you!
