Other Parts Discussed in Thread: SYSBIOS

Hi,

I have a question.

If I call Task_create like below

Task_Params_init(&taskParams);
taskParams.priority = 3;
Task_create(SRR_MSS_initBiosTimer, &taskParams, NULL);

Do I need to call Task_delete() to delect it?

/* Create a MCU timer */
static void SRR_MSS_initBiosTimer (UArg arg0, UArg arg1)
{
Timer_Params timerParams;
Error_Block eb;
Error_init(&eb);
Timer_Params_init(&timerParams);
timerParams.period = (TM_ISR_10MS_CNT)*1000; //msec
timerParams.periodType = Timer_PeriodType_MICROSECS;
timerParams.arg = 1;
timerParams.startMode = Timer_StartMode_USER;
//timerParams.priority = 3;

/* sysbios timer */
gTimerHandler = Timer_create(Timer_ANY, TimerIsr, &timerParams, &eb);

if (gTimerHandler == NULL)
{
System_abort("Timer create failed");
}

/* start the MCU Timer */
Timer_start(gTimerHandler);

//???????????????????????//

//Task_delete()

}

Hi,

It is my understanding that an explicit task delete is not needed with SYS/BIOS at the end of the task. This reflects in the init tasks of TI out of box demo/ TIREX labs.

Hi,

I try to do more Task_Create();

I find it will be crash and can't run.

How do I solve it?

/* Initialize the Radar App Parameters. */
Task_Params_init(&taskParams);
taskParams.priority = 3;
Task_create(SRR_MSS_initParameter, &taskParams, NULL);

/* Initialize the PeripheralDevice. */
Task_Params_init(&taskParams);
taskParams.priority = 3;
Task_create(SRR_MSS_initPeripheralDevice, &taskParams, NULL);

/* Initialize the BiosTimer. */
Task_Params_init(&taskParams);
taskParams.priority = 3;
Task_create(SRR_MSS_initBiosTimer, &taskParams, NULL);

/* Initialize the Task Parameters. */
Task_Params_init(&taskParams);
taskParams.priority = 3;
Task_create(SRR_MSS_initmmWaveTask, &taskParams, NULL);

// More to Crash

/* Initialize the Task Parameters. */
//Task_Params_init(&taskParams);
//taskParams.priority = 3;
//Task_create(SRR_MSS_initmmActiveWaveTask, &taskParams, NULL);

Hi,

It seems like the system is running out of heap to allocate the stacks of various tasks in this case.
