Can't create/connect to socket

Hi,

I followed instuctions from webinar to create a TCP/IP interface and connect to socket.

The interface is created and is pingable- but i can't connect to socket

here's my code

uint_32     error;
uint_32     sock, listensock;
sockaddr_in    addr;
char     str[] = "\nHello ZEFT\n";
   int len;

   _io_socket_install("socket:");
   _io_telnet_install("telnet:");

error = RTCS_create();

   _IP_forward = TRUE;
   IPCFG_default_enet_device = ENET_DEVICE;
   IPCFG_default_ip_address = ENET_IPADDR;
   IPCFG_default_ip_mask = ENET_IPMASK;
   IPCFG_default_ip_gateway = 0;

   ENET_get_mac_address (IPCFG_default_enet_device, IPCFG_default_ip_address, IPCFG_default_enet_address);

   ipcfg_init_device (IPCFG_default_enet_device,IPCFG_default_enet_address);
   error = ipcfg_bind_staticip(IPCFG_default_enet_device, &IPCFG_default_ip_address);

listensock = socket (PF_INET, SOCK_STREAM, 0);

/* bind the socket to a port */
addr.sin_family = AF_INET;
addr.sin_port = 23;
addr.sin_addr.s_addr = INADDR_ANY;

error = bind(listensock,&addr,sizeof(addr));
error = listen(listensock,0);

for (;
{

     sock = accept(listensock,NULL, NULL);

  if (sock != RTCS_SOCKET_ERROR)
  {
   send(sock,str,sizeof(str)-1,0);
   shutdown(sock,FLAG_CLOSE_TX);
  }

}

when i try to debug it... as soon as the code gets to sock = accept (listensock,NULL,NULL) it disrupts the program.

please help me anyone,

I spent two days staring at this code

thanks,

Hi Livy1234,

What training?

Do you have link to send?

Did you recompile the RTOS to ensure the libraries were up-to-date?

Have you tried any of the existing demo's? Look in FSLMQX/rtcs/examples/shell and try running it and let me know if that is working.

Regards,

David
