Hossam,

I'm able to run the example without issue on the AM437x EVM. Please verify that DHCP is correctly configured on your LAN. Also I assume you imported this example into CCSv6 and built?

Hossam,

It should work on the IDK, but I have not tried. Could you load the program and step through the code? It seems that the DHCP is stalling in lwip_lib.c around the code snippet below. Also, did you ensure that DHCP is working on your LAN?

 while((E_FAIL == retVal) && (dhcpTries--))
        {
            LWIP_PRINTF("\n\rDHCP Trial %d...", (NUM_DHCP_TRIES - dhcpTries));
            dhcp_start(pNetIf);

            cnt = LWIP_DHCP_TIMEOUT;

            /* Check for DHCP completion for 'cnt' number of times, each 10ms */
            while(cnt--)
            {
                delay(10U);
                pState = &(pNetIf->dhcp->state);

                if(DHCP_BOUND == *pState)
                {
                    retVal = S_PASS;
                    break;
                }
            }
