Problem in Ethernet Communication

utsavikalpesh — Sat, 22 Feb 2014 05:35:49 GMT

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:

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:

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.

Regards,

Garabo
