stm32h7 ethernet tcp connection lwip

netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &tcpip_input);

I am using open source ethernet code and i am having trouble while connecting. Also when I connect i see my desired output with ARPlines does that mean my connection is lost than connected again or is it just for affirmation for the connection

A couple of points for posting.

1. Always format your code. You managed to use code tags, but it still doesn't look nice to read.

  netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, &ethernetif_init, &tcpip_input);
  while (1) {
    netif_set_default(&gnetif);
    if (netif_is_link_up(&gnetif)) {
      netif_set_up(&gnetif);
      break;
    } else {
      netif_set_down(&gnetif);
    }
    netif_set_link_callback(&gnetif, ethernet_link_status_updated);
  }

2. JPG is for your camera. Use PNG format for saving screen shots containing digitally generated information like program output.
What you posted is borderline illegible.

Do you see regular ARP lines when your program isn't running?
