software hanging problem

Posted by Nobody/Anonymous on April 3, 2007
Hi every one.
I am new with FreeRTOS but getting very strange problem.I have one device having msp430F1611 with CC2420 radio, which send packets at 25 Hz.Another device having the same specification but its sends the packets at 200Hz. (Both devices are programed with FreeRTOS)when i trun on one device alone it works fine but if I trun on both devices together then the device(50Hz) sending packet for a some interval and after that it get hanged or stops sending packets...could any one please guide me what is the problem with the code provided below..it would be nice if someone gives some comments.
Thanks.

here is the sample code..Thanks..


int main( void )
{
bus_init(); /* Initialize hardware */
LED_INIT();
/* Start debug library at 115.2 kbps */

/* Initialize Stack */

// Create FreeRTOS Tasks, slightly higher priority to the normal task
xTaskCreate(vtest, "T", configMINIMAL_STACK_SIZE + 364, NULL,tskIDLE_PRIORITY, NULL );

// Start the FreeRTOS Scheduler
vTaskStartScheduler();
return 0;
}



static void vtest( void *pvParameters )
{
socket_t *n_socket = 0;
buffer_t *n_buffer = 0;
portTickType xLastWakeTime;
xLastWakeTime = xTaskGetTickCount();
vTaskDelayUntil(&xLastWakeTime, 1000 / portTICK_RATE_MS );

//create and open socket
n_socket = socket(MODULE_NUDP, 0);
if (!n_socket)
{
debug("P: Socket creation failed.\r\n");
LED2_ON();
return; /* Exit */
}

for (;;)
{
if (n_socket)
{
n_buffer = socket_buffer_get(n_socket);
if (n_buffer)
{
//allocate buffer
//reading adc values and put in the buffer after that send them
}
}

}

}
