xemacif_input(netif) in FreeRTOS

Posted by Anurag on June 20, 2012
I am Facing a issue while calling xemacif_input(netif)in FreeRTOS task using TCP and UDP Connection establishment.This is a example of LWIP echo sever.

Often people don't provide enough information to allow forum members to reply. In this case, all you have said is "I'm facing an issue". The only sensible reply is then "what is the issue?", so why didn't you say in the first place?

I suggest you read the FAQ on using the forum (link at top of forum front page), and then ask your question on the lwIP forum as it does not look like a FreeRTOS question anyway.

Dear Sir
Thanks for reply.I am using LWIP1.3.0 and make ACS_TCP_Server task in FreeRTOS

void prvACS_TCP_ServerTask (void* pvParameters)
{
(void) pvParameters; // Just to stop compiler warnings.
//err_t Err;

static int gi_TCP_Server_Connection_Status= TCP_SERVER_DISCONNECTED;

for (;;) {

// if(gi_TCP_Server_Connection_Status!=TCP_SERVER_DISCONNECTED){

// }



/* receive packets */
xemacif_input(netif);
/* do application specific processing */


switch(gi_TCP_Server_Connection_Status){

case TCP_SERVER_DISCONNECTED:
#ifdef DEBUG_PRINT
print("TCP disconnected\n\r");
#endif

InitACS_TCP_SERVER();
gi_TCP_Server_Connection_Status=TCP_SERVER_INITIALIZED;

#ifdef DEBUG_PRINT
print("TCP initialized\n\r");
#endif

break;

case TCP_SERVER_INITIALIZED:

gi_TCP_Server_Connection_Status=TCP_SERVER_CONNECTED;
break;

case TCP_SERVER_CONNECTED:
#ifdef DEBUG_PRINT
print("TCP Connected\n\r");
#endif


break;


default:
gi_TCP_Server_Connection_Status=TCP_SERVER_DISCONNECTED;
break;
}

print("TCP\n\r ");

vTaskDelay(1);
}
}

This function i am, using for Transmit packets for raw API for xemacif_input(netif);
between TCP and UDP Connection establishment.

Can you help to guide.how can we used this function in FreeRTOS in xemacif_input(netif);

Regards
Anurag Gupta

Dear Sir

I want to be used Keil as Development IDE and Ported current Project for Supported Demo of FreeRTOS ARM9_AT91SAM9XE_IAR for Atmel microcontroller is using IAR Tools as development any Application.As per my knowlege files that’s is Provided by IAR tools in FreeRTOS in FreeRTOSV7.1.0\Source\portable\IAR\AtmelSAM9XE


•ISR_Support.H
•Port.c
•Portasm.s79
•Portmacro.c
From where i can get these Files for used KIEL as development IDE for My Application Development Application for atmel microcontroller project of FreeRTOS Demo ARM9_AT91SAM9XE_IAR .

Hi Richard

I am able to run LWIP using netconnAPI on Atmel microcontroller.that was major achivements of till date for me in FreeRTOS.Thanks for your support and guidelines.

Anurag Gupta
