Hi everyone!  
I’m novice on freeRTOS…  
i’m writing some code on sam3x8e and works great for the first 10s …  
after this time freeRTOS seems to reboot and so on!!!  
any ideas for the problem!?  
thanks a lot.

I’m afraid you will have to provide more information in order to get a helpful reply. As it is all we could do is list out 100 different possibilities from the power supply browning out to your code overwritting critical data to a watchdog not being kicked.

okey…Well…

uController -\> Atmel sam3x8e  
compiler -\> ARM/GNU C compiler  
freeRTOS version -\> 7.3.0  
SDK -\> Atmel studio 7.0 with ASF

My application it’s composed by a simple task(sender) that create som messages and send theme to a specifica Queue and than it delete itself. To the other side there’s a task(motor\_manager) that recive the messages from the queue and do some stuff. There’s the code:

Task sender:

void sender(void\* pvParameters)  
{  
uint8\_t rxValue;  
motor\_cmd cmd2 = {10,CCW,1,START};  
motor\_cmd cmd3 = {10,CCW,2,START};  
motor\_cmd cmd4 = {10,CCW,3,START};  
motor\_cmd cmd1 = {10,CCW,0,START};  
uint8\_t carattere = 33;  
vTaskDelay(1000/portTICK\_RATE\_MS);  
xQueueSend(tx\_queue,&carattere,0);  
xQueueSend(incoming\_message,&cmd1,0);  
xQueueSend(incoming\_message,&cmd2,0);  
xQueueSend(incoming\_message,&cmd3,0);  
xQueueSend(incoming\_message,&cmd4,0);  
while(1);  
}

Task motor\_manager:  
void motor\_manager(void\* pvParameters)  
{  
portBASE\_TYPE xStatus;  
motor\_cmd in\_msg;  
for (int i = 0;i \< 8;i++)  
{  
if(pwm\_ch\_enable[i] == 1)  
{  
pwm\_ch\_enabled[i] = i;  
nMotors[i].status = IDLE;  
nMotors[i].isEnabled = true;  
nMotors[i].cmd\_steps = 0;  
nMotors[i].remaning\_steps = 0;  
pio\_configure\_pin(CH0\_PIN + i,PIO\_TYPE\_PIO\_OUTPUT\_0);  
pio\_set\_pin\_low(CH0\_PIN + i);  
xStatus = xTaskCreate(motor\_channel\_manager,“Gestore\_canale”,configMINIMAL\_STACK\_SIZE,&pwm\_ch\_enabled[i],CHANNEL\_TASK\_PRIORITY,NULL);  
if(xStatus != pdPASS)  
{  
A9488\_drv\_fault = true;  
vTaskDelete(NULL);  
}  
}  
}

```
vTaskPrioritySet(NULL,(configMAX_PRIORITIES - 3));
while(1)
{
	if (uxQueueMessagesWaiting(incoming_message) > 0)
	{
		xQueueReceive(incoming_message,&in_msg,portMAX_DELAY);
		if(nMotors[in_msg.ch].isEnabled && nMotors[in_msg.ch].status == IDLE)
		{
			nMotors[in_msg.ch].cmd_steps = in_msg.n_steps*2;
			nMotors[in_msg.ch].remaning_steps = nMotors[in_msg.ch].cmd_steps;
			nMotors[in_msg.ch].rot = in_msg.direction;
			nMotors[in_msg.ch].status = RUNNING;
		}
	}
	taskYIELD(); 
}

```

}

the main:

int main (void)  
{  
sysclk\_init();  
board\_init();  
irq\_initialize\_vectors();  
cpu\_irq\_enable();

```
xTaskCreate(init_system_task,"Boot_task",configMINIMAL_STACK_SIZE,NULL,(configMAX_PRIORITIES - 2),NULL);
xTaskCreate(sender,"sender_task",configMINIMAL_STACK_SIZE,NULL,TX_PRIORITY,NULL);
vTaskStartScheduler();
while(1);

```

}

the code seems work great…but after 10s it crash and reboot…i tryed to disable the WDT but nothing happends!!!..the only things i’ve changed in freeRTOSConfig.h is:  
configUSE\_MALLOC\_FAILED\_HOOK (1 -\> 0)  
because the compiler give me some errors.  
thanks  
Tommaso.

the problem doesn’t appear during debug with atmel ICE JTAG!!!

IAR JTAGs can run a script to config some registers before debugging starts. Does your ICE do the same?

Can you use a newer version so configASSERT() will be more useful to you?

So far _ALL_ my problems of system rebooting after some time were due to  
stack overflow…

But that was easy to catch as I implemented the function supplied as an  
example that shows stack usage for each task.  
I also added main stack usage and free memory…  
That is really an invaluable tool

SOLVED…it was a problem with the watch dog timer…  
it wasn’t correctly disabled…i don’t no really why but disable the watch dog from a task won’t wok…but disable it from the main works correctly!!!  
thanks everyone for HELP.  
Tommaso.
