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.
RE: suspend taskPosted by Braun on February 9, 2012 When I goto vTaskSuspend( Task3 ); then it goes no further, because Task4 and Task5 are not generated.
Why?
RE: suspend taskPosted by Braun on February 9, 2012 Ok now I gernerate Task4 und Task5 but now when i goto vTaskSuspend( Task3 ) it stopped
RE: suspend taskPosted by Richard on February 9, 2012 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.
RE: suspend taskPosted by Braun on February 9, 2012 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.
