Starting more than two tasks in RTOS

Question

I'm new in RTOS, my problem is that I can not start more than 2 tasks at the same time. I'm using FREE-RTOS. The task priorities are set to the same level of priority. And configTOTAL_HEAP_SIZE is set on 8192 bytes.

Could anyone help me with this, or give me some direction?

Please post some code. But I'd guess that your tasks are being given too much stack space... — Roddy, Jan 10 '14 at 15:03

I have 3 tasks with the same structure.

#define configTOTAL_HEAP_SIZE       ( ( size_t ) ( 2 * 1024 ) )

xTaskCreate(Task3, (signed char *)"T3", ( ( unsigned short ) 100 ), NULL, 2, NULL);

vTaskStartScheduler();


static void Task3( void *pvParameters )
{
    portTickType xNextWakeTime;
    xNextWakeTime = xTaskGetTickCount();
    for( ;; )
    {
        vTaskDelayUntil( &xNextWakeTime,(3 * mainQUEUE_SEND_FREQUENCY_MS));
    }
}
