Hello,

if have a Problem when i suspend more tasks. I work on IAR, EFM32G290F128.

Task1()Priority:3  
{  
\_\_\_xTaskCreate(Taks2,…);  
\_\_\_xTaskCreate(Taks3,…);  
vTaskSuspend( Task1 );  
…  
}

Task2()Priority:2  
{  
\_\_\_xTaskCreate(Taks4,…);  
vTaskSuspend( Task2 );  
…  
vTaskResume(Task1);  
….  
}

Task3()Priority:2  
{  
\_\_\_xTaskCreate(Taks5,…);  
vTaskSuspend( Task3 );  
…

vTaskResume(Task1);  
…  
}

Task4()Priority:1  
{  
…  
vTaskResume(Task2);  
…  
}  
Task5()Priority:1  
{  
…  
vTaskResume(Task3);  
}

When I goto vTaskSuspend( Task3 ); then it goes no further.

When I goto vTaskSuspend( Task3 ); then it goes no further, because Task4 and Task5 are not generated.

Why?

This is an immensely complex scenario that I don’t want to work through, but even if I did there is no way I could possibly tell which task would run when without knowing their priorities.

Regards.

The priorities are:  
Task1 -\>3  
Task2 -\>2  
Task3 -\>2  
Task4 -\>1  
Task5 -\>1

Task2 and Task3 are periodic tasks. Tasks2 Periode-\>100ms, Tasks3 Periode-\>50ms  
Task4 and Task5 will generate and after they are ready they delete themselves.  
Task1 ist active when Task2 and Task3 are in blocked state.
