Not possible to have infinite loops in Autostart non cyclic Tasks? #363

Closed ajithpadman closed 8 years ago

ajithpadman commented 8 years ago

I would like to know if it is possible to have Infinite While loop inside the Autostart tasks (which is not a cyclic task)which are supposed to be terminated after activating the other cyclic tasks? Currently when I tried it the other cyclic tasks not at all getting scheduled. Is there a way of doing this?

Or in more General Terms Is it possible to call the Scheduler explicitly without Terminating the Task? I want the autostart non cyclic task to run as a background task.

Hello Ajith,

we have an implementation of OSEK-VDX OS and not an AUTOSAR-OS.

You can call the scheduler from a non preemptive task, the interface is called Schedule.

From a full preemptive you dont have to do anything, the scheduler will activate tasks with higher prio automatically.

So you can configure a low prio task full schedule and perform a while 1 and never end.

Personally I would not recommend such scheduling but it can be done. While in while 1 the RTOS will never go to halt mode and consume a lot of current all the time. You can never stop such task. Better is to have a ciclic task or chain task at the end of a task to itself if needed.

Regards Mariano
