RTOS/CC1310: TI RTOS Idle Task

Part Number:CC1310

Tool/software:TI-RTOS

Hi ,

I am using cc1310.

Currently we are working on current consumption of our product.

For testing I run only one task that immediately goes to sleep forever.

Here the fragment of TI RTOS configuration file:

/*
* Enables the idle task.
*
* Pick one:
* - true (default)
* Creates a task with priority of 0 which calls idle hook functions. This
* option must be set to true to gain power savings provided by the Power
* module.
* - false
* No idle task is created. This option consumes less memory as no
* additional default task stack is needed.
* To gain power savings by the Power module without having the idle task,
* add Idle.run as the Task.allBlockedFunc.
*/
//Task.enableIdleTask = true;
//Task.enableIdleTask = false;

Task.allBlockedFunc = Idle.run;

But in the IAR  ti.sysbios.knl.Task Basic window we  see  :

i.e. ti.sysbios.knl.Task.idleTask is running.

In the scope( we measure the voltage we  see pick every 60-70 msec).

And the only task running is  Kernel  IdleTask.

I tried another configuration:

Task.enableIdleTask = false;

Task.allBlockedFunc = Idle.run;

 In the IAR  ti.sysbios.knl.Task Basic window we  see  :

i.e. ti.sysbios.knl.Task.idleTask is not exists.

In this case in the scope we see picks every 3 sec

Q: What is the right configuration of the Idle Task if we want to gain  power savings provided by the Power
    ? module.
