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. Tommaso

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) { uint8t rxValue; motorcmd cmd2 = {10,CCW,1,START}; motorcmd cmd3 = {10,CCW,2,START}; motorcmd cmd4 = {10,CCW,3,START}; motorcmd cmd1 = {10,CCW,0,START}; uint8t carattere = 33; vTaskDelay(1000/portTICKRATEMS); xQueueSend(txqueue,&carattere,0); xQueueSend(incomingmessage,&cmd1,0); xQueueSend(incomingmessage,&cmd2,0); xQueueSend(incomingmessage,&cmd3,0); xQueueSend(incoming_message,&cmd4,0); while(1); }

Task motormanager: void motormanager(void* pvParameters) { portBASETYPE xStatus; motorcmd inmsg; for (int i = 0;i < 8;i++) { if(pwmchenable[i] == 1) { pwmchenabled[i] = i; nMotors[i].status = IDLE; nMotors[i].isEnabled = true; nMotors[i].cmdsteps = 0; nMotors[i].remaningsteps = 0; pioconfigurepin(CH0PIN + i,PIOTYPEPIOOUTPUT0); piosetpinlow(CH0PIN + i); xStatus = xTaskCreate(motorchannelmanager,"Gestorecanale",configMINIMALSTACKSIZE,&pwmchenabled[i],CHANNELTASKPRIORITY,NULL); if(xStatus != pdPASS) { A9488drv_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) { sysclkinit(); boardinit(); irqinitializevectors(); cpuirqenable();

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: configUSEMALLOCFAILED_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.
