all the threads stop after running for a while

[amarjeet]

Hi,

I am using sdk 14.2.0.

i am using freeRTOS,created 3 threads.

all are running fine,but just for while(2 - 3 minutes).

after that, all the threads stoped.

may be deadlock situation occurs.here the snippet:

/*************************************************************/

static void led_thread(void * arg)
{
UNUSED_PARAMETER(arg);

while (1)
{
all_led_off();
printf("\r\nLED OFF \r\n");
vTaskDelay(1000);

all_led_on();
printf("\r\nLED ON \r\n");
vTaskDelay(1000);
}
vTaskDelete( NULL );
}

-------------------------------

static void audio_thread(void * arg)
{
UNUSED_PARAMETER(arg);
printf("%d\r\n",airtel_size);
while(1)
{
play_audio();
vTaskDelay(1000);
printf("audio\r\n");
}
vTaskDelete( NULL );
}

----------------------------------

static void vib_motor_thread(void * arg)
{
UNUSED_PARAMETER(arg);
while(1)
{

pwm_update_duty_cycle(100);
printf("\r\nmotor start \r\n");
vTaskDelay(5000);

pwm_stop();
printf("\r\nmotor stop \r\n");
vTaskDelay(3000);

pwm_start();
}
vTaskDelete( NULL );
}

/************************************************************************************/

main.c

---------

if (pdPASS != xTaskCreate(led_thread, "LED", 256, NULL, 1, &m_led_thread))
{
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
}

if (pdPASS != xTaskCreate(audio_thread, "AUDIO", 256, NULL, 1, &m_audio_thread))
{
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
}
if (pdPASS != xTaskCreate(vib_motor_thread, "VIB_MOTOR", 256, NULL, 1, &m_vib_motor_thread))
{
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
}
// Activate deep sleep mode.
SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;

// Start FreeRTOS scheduler.
vTaskStartScheduler();

what might be the problem???

please guide me.

Thanks

hard to say looking at this code. can you attach the project so that I can test it?

[amarjeet]

no aryan,i cannot attach the project code,but i can give u some more information...my project is integrated with BLE module...once BLE stops advertising...or we can say...once advertising time is over...all the thread exits...is that means...main exits after that?????????? 

[Susheel Nuguru]

you cannot exit a task after it is created. You need to delete it if you see no more use of the task being run in the RTOS scheduler.

In our examples when BLE stops advertising, not all thread exit. It depends on how you design your tasks.
