Hi,

Two tasks

Task 1 with high priority

Task 2 with low priority

Task2 is in between exectution of critical section to receiving or transmission of data.

1) Now how to block Task 1 (High priority task) during exection of Task 2 in critical section?

2)Can you mention the API which can be included before and after execution of critical section?

 

 

Regards,

Bindu

    Hi Bindu,

    One way you can do this is to disable the Task scheduler before your critical section and then re-enable it after.  This is done using the Task_disable() and Task_restor() APIs.  You can also use gates.

    Please refer to the BIOS User's Guide for details.  In particular, see chapter 4 Synchronization Modules and section 4.3.1.3 GateTask.
