System View

Is there anything such as Systemview "in the pipe"?
It seems it is really useful, but it can only be used with J-Link
in "streaming mode". See

  • Yes, there is a System View in MDK, but it is something entirely different.
    For Segger, it means a utility based using real time transfer of data
    visualizing context switches for Task & Interruots, with sub-us accuracy.
    It seems Keil does not have that same thing, but ic can probably be used
    in parallel to MDK with a J-Link debug probe.

  • OK, I think I found the solution to use Segger's Systemview with MDK.
    Actually multiple solutions.

    One is to simply safe the buffer. This also works with ULINK.
    Disadvantage: Single shot mode only, limit by amount of available RAM.
    Still quite useful.

    Or: Use J-Link in parallel to MDK
    Or: Use J-Link on a release build (which will give you more
    accurate timing information anyhow, as one really wants to know
    what the timing of a release build is, not a debug build), so run
    Systemview without MDK

  • Hi Dirk. You might want to have a look at our Tracealyzer tools, see http://www.percepio.com.
