Ethernet Communication Problem

Hi All,

I am using TWR-K60D100M for ethernet communication.I have created new mqx4.0 project and write the following code for that.

/****************************************************************************

* This file contains MQX only stationery code.

#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*-----------------------------------------------------

void Main_task(uint_32 initial_data)

{

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)

}

/* EOF */

but after running it indicate that "Socket is not created"..PLz help me

I copied your code into hello.c , and debugged it on TWR-K60D100M, found that the socket was created successfully. How many tasks running in your system? Please check your MQX stack usage. Maybe you need to increase the stack size if there is no enough memory.
