I have downloaded FreeRTOS. I have used demo application for PC. It was working fine.

I have modified main.c.

main.c has this much only other than this i have deleted.

portSHORT main( void )
{
xTaskCreate( vErrorChecks, "Print", mainPRINT_STACK_SIZE, NULL, mainPRINT_TASK_PRIORITY, &xHandle );

vTaskStartScheduler();

}

static void vErrorChecks( void *pvParameters )
{

for(;;)
{

xQueueSend()

xQueueReceive()

/*some printfstatements */
}

}


It compiled fine , while running it stucks after 1 sec nearly & shows error

if anyone find solution ,please let me know.

It does not look like you are creating the queue anywhere that you are then attempting to send to and read from. You need to create a queue before it can be accessed.

Regards.

ohh sorry i forgot to mension it. In main.c i have created queue. this is not problem.
