Problem in Ethernet Communication

[utsavikalpesh]

Hi,

I am using TWR-K60D100M having microcontroller of MK60DN512VMD10.

For ethernet communication I have created new project in MQX4.0 and have write the code below in Source->main.c.

#include "main.h"

#include <rtcs.h>

#include <ipcfg.h>

#include <fio.h>

#include <mqx.h>

#include <bsp.h>

#if !BSPCFG_ENABLE_IO_SUBSYSTEM

#error This application requires BSPCFG_ENABLE_IO_SUBSYSTEM defined non-zero in user_config.h. Please recompile BSP with this option.

#endif

#ifndef BSP_DEFAULT_IO_CHANNEL_DEFINED

#error This application requires BSP_DEFAULT_IO_CHANNEL to be not NULL. Please set corresponding BSPCFG_ENABLE_TTYx to non-zero in user_config.h and recompile BSP with this option.

#endif

uint_32 (_CODE_PTR_ const RTCS_protocol_table[])(void) = {

RTCSPROT_TCP,

NULL

};

TASK_TEMPLATE_STRUCT MQX_template_list[] =

{

/*  Task number, Entry point, Stack, Pri, String, Auto? */

   {MAIN_TASK,   Main_task,   1500,  9,   "main", MQX_AUTO_START_TASK},

   {0,           0,           0,     0,   0,      0,                 }

};

/*TASK*-----------------------------------------------------

*

* Task Name    : Main_task

* Comments     :

*    This task prints " Hello World "

*

*END*-----------------------------------------------------*/

void Main_task(uint_32 initial_data)

{

  IPCFG_IP_ADDRESS_DATA ip_data; _enet_address mac_address;

  uint_32 error;

  uint_32 sock,listensock;

  sockaddr_in addr;

  char str[] = "\n Hello World \n";

  uint_32 value;

  printf("\n Hello World \n");

  _RTCSPCB_init = 4; _RTCS_msgpool_init = 4; _RTCS_socket_part_init = 2; _RTCSTASK_priority = 8;

  error = RTCS_create();

  ip_data.ip = IPADDR(169,254,1,200);

  ip_data.mask = IPADDR(255,255,0,0);

  ip_data.gateway = 0;

  ENET_get_mac_address(BSP_DEFAULT_ENET_DEVICE, ip_data.ip,mac_address);

  ipcfg_init_device(BSP_DEFAULT_ENET_DEVICE, mac_address);

  error = ipcfg_bind_staticip(BSP_DEFAULT_ENET_DEVICE, &ip_data);

  listensock = socket(PF_INET, SOCK_STREAM, 0);

  value = 256;

  setsockopt(listensock,SOL_TCP, OPT_TBSIZE, &value, sizeof(value));

  setsockopt(listensock,SOL_TCP, OPT_RBSIZE, &value, sizeof(value));

  value = 1000;

  setsockopt(listensock,SOL_TCP, OPT_TIMEWAIT_TIMEOUT, &value,sizeof(value));

  /* Bind the socket to the Telnet port */

  addr.sin_family = AF_INET;

  addr.sin_port = IPPORT_TELNET;

  addr.sin_addr.s_addr = INADDR_ANY;

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

  error = listen(listensock, 0);

  while (1) {

  sock= accept(listensock, NULL, NULL);

  if (sock != RTCS_SOCKET_ERROR) {

  send(sock,str, sizeof(str)-1,0);

  shutdown(sock,FLAG_CLOSE_TX);

  }

  }

  // _mqx_exit(0)

}

but after running program,when I connect socket it indicate "Socket is not Connected".What to do??Is there any other way for ethernet communication..Plz reply ...:smileyconfused::smileyconfused::smileyconfused:

Hi Utsavi,

Try to use this function:

void initialize_networking(void)

{

    uint_32 error;

    IPCFG_IP_ADDRESS_DATA auto_ip_data;

    _enet_address enet_address;

    _int_install_unexpected_isr();

    auto_ip_data.ip = ENET_IPADDR;

    auto_ip_data.mask = ENET_IPMASK;

    auto_ip_data.gateway = ENET_IPGATEWAY;

    /* Init RTCS */

    _RTCSPCB_init = 4;

    _RTCSPCB_grow = 2;

    _RTCSPCB_max = 8;

    _RTCSTASK_stacksize = 4500;

    error = RTCS_create();

    ENET_get_mac_address (BSP_DEFAULT_ENET_DEVICE, ENET_IPADDR, enet_address);

    error = ipcfg_init_device(BSP_DEFAULT_ENET_DEVICE, enet_address);

    ipcfg_bind_dhcp_wait(BSP_DEFAULT_ENET_DEVICE, TRUE, &auto_ip_data);

    ipcfg_get_ip(BSP_DEFAULT_ENET_DEVICE, &auto_ip_data);

    printf("\nIP Address      : %d.%d.%d.%d",IPBYTES(auto_ip_data.ip));

    printf("\nSubnet Address  : %d.%d.%d.%d",IPBYTES(auto_ip_data.mask));

    printf("\nGateway Address : %d.%d.%d.%d",IPBYTES(auto_ip_data.gateway));

    printf("\nDNS Address     : %d.%d.%d.%d\n",IPBYTES(ipcfg_get_dns_ip(BSP_DEFAULT_ENET_DEVICE,0)));

}

After you call this function and if the ethernet cable is connected and you are using a DHCP server then you will be able to use sockets.

For a socket usage example take a look to this code http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4417SW.zip which belongs to the appnote AN4417.

You can also use the code from this other thread Re: Embedded server

I hope this solves the issues.

Hey Utsavi,

I am facing the same problem.If u got the solution Plz forward it to me.....Or If anybody have solve this plz answer it......I am really confused....!!!!:smileyangry::smileyangry:
