Hello,

Does it possible create two infinite loops task on one core? I red about extended tasks in Erika V3.

Could you give me example OIL.

Thank you.

There are various event demos in the templates available in the standard distribution. just instantiate one of them...

Thank you for fast answer.

But in examples i can't use infinite loops, i should use WaitEvent and wait event.

I need something like that.

Code: Select all

TASK(Producer)
{
	for (;;){}
}

TASK(Consumer)
{
    for (;;){}
}

Code: Select all


    TASK Consumer {
        PRIORITY = 2;
        ACTIVATION = 1;
        STACK = PRIVATE {
            SYS_SIZE = 256;
        };
        AUTOSTART   = TRUE;
        SCHEDULE = NON;
        EVENT = ProducerEvent;
    };

    TASK Producer {
        PRIORITY = 3;
        ACTIVATION = 1;
        STACK = PRIVATE {
            SYS_SIZE = 256;
        };
        AUTOSTART   = TRUE;
        SCHEDULE    = NON;
        EVENT       = ConsumerEvent;
    };

but it doesn't work. Execution only Producer. it looks like green threads https://en.wikipedia.org/wiki/Green_threads

When a green thread executes a blocking system call, not only is that thread blocked, but all of the threads within the process are blocked

Can you help me?

ERIKA is an AUTOSAR OS. Please check the specification, the scheduling is priority driven, with immediate priority ceiling. No Round Robin.
