Other Parts Discussed in Thread: SYSBIOS

Hi ,

I am facing a problem where from accumulator ISR semaphore post is happening and the task pending on semaphore is not waking up.

Using task_stat api confirm semaphore post is successful since task mode is show after post is "ti_sysbios_knl_Task_Mode_READY" and CPU is free but scheduler is not scheduling this task.

BIOS version : 6_35_04_50

XDC : 3.24.07.73

CGT : 7..3.5

can someone help in understanding what is the problem here.

Hi Rahul,

Which hardware platform are you using?

What is the priority of your task?

When the problem occurs, can you halt the processor and open the ROV tool?

What do you see in the Task module view?

It may be helpful if you post some screen shots of what you are seeing in ROV.

Hi Steve

I am using EVM 6670.

The task priority is 4.

I am not using CCS debugger so getting ROV information is not possible.

Is there any other way/APIs to target this problem ?

Which debugger are you using?

Or is this a deployed system?
