  • [ABANDONED] Sum of CPU loads does not match with Idle %


    I am using SystemView on my project and it seems to work well as the execution times and periodic events match with what I expected.
    There is one thing that I do not understand is that the Idle % does not match with (100% - Sum of CPU load %). -> Picture1
    I count 13,08% of CPU load so I expect to have 86,92% Idle but I got 96,19% ? Am I wrong ?

    Another things I noticed :
    -While recording, "Idle %" is not steady, even after several seconds. I think the value in the column "CPU Load" is average for the recording duration, am I wrong ?
    -The timestamped thread say very often "Idle For xxx ms" (where xxx is several hundreds of milliseconds) but in the timeline, I do not find this kind of time. Idle time seems to be always between 0 and 1ms (And it is what I expect as my Systick is 1ms) -> I attached an example of this issue (Picture2)

    I am using :
    -SystemView v3.10
    -uCOS-II V2.92.16
    -J-Link Ultra+ 4.4

    Thanks for your help

  • Hello,

    Thank you for your inquiry.
    Could you give the latest SystemView version a try? There has been a fix for high load application recordings.
    Does the display improve?
