  • [SOLVED] Timeline not showing any of the task or systick events in graphical form

    I am using a Cortex M3 controller with FreeRTOS v10 and applied all the changes as per the below link
    wiki.segger.com/FreeRTOS_with_SystemView

    When I captured the recording, I am able to see all the systick ENTER/EXIT and task switching in the log.(attached : SystemView.PNG)
    But the timeline window is completely empty and not showing any of those events graphically.

    Is there any module which I have to enable in SystemView inorder to view in graphical form like this (attached : expected.png)

    I am also attaching the log which I captured (attached as log_SVDat.txt, please rename to log.SVDat to open in Segger SystemView).

  • Hello,

    Thank you for your inquiry.
    It appears that the instrumentation of the FreeRTOS sources was not successful as your recording shows only Systick ISRs.
    I would expect at least one task to be running + the scheduler.

    Did you make sure that all necessary instrumentation steps have been applied?
    For more information see SystemView manual UM08027_SystemView.

    Best regards,
    Nino

    Hi Nino,

    If you look at the image : SystemView.png, you could see three things,
    1) Systick Interrupt ENTER and EXIT
    2) Hello task switch in and out
    3) Idle task

    In the log file which I have shared, there would be 3 times Hello task coming in and out.
    But none of these events are shown in the timeline.

    Is there any additional event which is missing and needed by timeline?
