TMS570LS3137: LWIP DEMO Not working

Hi

I have TMDS570LS31HDK, I am not successful in getting Ethernet working. All the necessary switch locations are taken care.

LWIP Demo downloaded from the link provided in the Halcogen tool, compiled and loaded, when started running, it runs until DEBUG-Setting up Link...SUCCESS and hangs forever.

When debugger paused code is at hdkif.c file

    while (EMAC_BUF_DESC_EOQ != (curr_bd->flags_pktlen & EMAC_BUF_DESC_EOQ));

Later I tried another attempt to change to STATIC IP, this time I get through until the message on terminal displays last line web server accessible..... etc

But can not connect to network.

Thanks
