LWIP on STM32H7 and Cubemx not working

[SS.Sagar]

I am using STM32H7 MCU and Cubemx ide. I am facing an issue with ethernet connectivity with the Nucleo board which has STM32H743 mcu.

I have configured Connectivity ETH and set the mode to RMII and enabled LWIP from the middleware.

I tried DHCP enable and disable but I could not do established the connection with Nucleo.

with DHCP disable following were changes in IP assignment

IP : 192.168.1.200

Netmask address: 255.255.255.0

Gateway Address: 192.168.1.1

With DHCP enabled I was trying to get the IP as follows,

	  local_SubNet = ip4_addr_get_u32(netif_ip4_netmask(&gnetif));
	  local_Gateway = ip4_addr_get_u32(netif_ip4_gw(&gnetif));
	  local_IP = gnetif.ip_addr.addr;

I have attached .ioc (cubemx configuration) file here. And attached screenshot of the connection in windows pc.

Here is a simple LwIP example for Nucleo STM32H743. If it works for you, examine your Cube generated initialization code and merge.

What _is_ working?
