RL-ARM http-server

Hello!

I'm trying to run HTTP-server on my LPC1788 board. lwip stack works fine. But when I try to run http-server under RL-ARM programm doesn't start at all. I included to my project follow files: EMAC_LPC177x_8x.c, Net_Config.c, TCP_CM3.lib, TCPD_CM3.lib (and corresponding headers Net_Config.h, EMAC_LPC177x_8x.h). Here my program:

include "LPC177x_8x.h"
#include "debug_frmwrk.h"
#include "RTL.h"

int main (void)
{
   SystemInit();

        debug_frmwrk_init();
        _DBG_("Started!");

        init_TcpNet ();

   while (1)
   {
      main_TcpNet();
   }

}

I want just to try ping my board from my PC Ethernet. Do you mind to explain to me what is wrong?

Regards, Vasilij.
