Part Number: TMDSIDK437X
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

Hello,

I would like to measure CPU Load using ROV in tamagawa_diagnostic project.

I removed Program.sectionsExclude line in cfg file with reference to the bellow thread because failed to launching ROV firstly.

But I can't display CPU load graph.

Could you tell me how to measure CPU Load using ROV?

Regards,

U-SK

    Hi,

    We have the UIA user guide here: software-dl.ti.com/.../index_dsp_sw.html , can you take a look if it helps?

    Also, can you attach your .cfg file for us to check, and what is the SYSBIOS, XDC, UIA package versions for this?

    Regards, Eric

    U-SK,

    Please make sure that your BIOS application has a Idle task defined when you are trying to do CPU Load analysis. The way the UIA/RTOS tools measure CPU Load is the time spent by the core executing task other than Idle so if you don`t have Idle defined then you may not see the correct CPU load.

    The precise description of how the CPU Load works and how to use the CPU Load View is in section 4.10 of the user guide herE:
    www.ti.com/.../spruh43f.pdf

    The tool also provides CPU Load summary that shows max, min and average CPU load.

    Regards,
    Rahul

    PS: For CPU load analysis, in addition to the ROV, you will also need to open the System Analyzer View from Tools->System Analyzer
