I am trying a simple example code for running the server in stm32f407, I have used LAN 8720. The connection are as follows:
PA1 -----nINT/RETCLK
PA2-----MDIO
PA7-----CRS
PB11----TX_EN
PB12---TX0
PB13---TX1
PC1----MDC
PC4----RX0
PC5----RX1
my settings in the cube ide are:
RCC--> HSE:crystal/ceramic Resonator
SYS---> Debug: trace asynchronous SW
CONNECTIVITY----> ETH: RMII
MIDDLEWARE---> LWIP setting:

My clock configuration settings:

my main.c is attached below.
I am not able to figure out the problem. I am pinging the IP and it is not responding, the page is showing error "server not responding"
