Using SystemView for debugging

morpho

Hello

I am testing out a blinky FreeRTOS example that's a part of the SDK and would like to use SystemView to visualize context switching and tasks. Are there any steps to go about using SystemView for debugging?

    There is a blogpost for this specific usecase. I recommend you to use only the part which covers profiling of the application and not the softdevice. The softdevice profiling is done using smart hacks and workarounds very specific to that older version of the softdevice.

    Thanks for the response.

    So you're implying I should skip steps involving the softdevice?

    A couple of initial questions:

    • when it talks about creating a systemview folder in the project, is it referring to the local path or inside the Segger IDE? Because they aren't mapped.
    • Where's Src/Config? It's currently not set up like that in ble_app_hrs_freertos example project. In fact, main.c is a part of the base folder and there's no such folder as Src.
    • Global.h are located under external/segger_rtt. Is there where I should be copying the files to my project?

     This will be in your filesystem and in your project folder. The blog author has created a copy of hrs freertos example folder as quoted below.

    "The following steps are based on the Heart Rate application with FreeRTOS example located in the SDK (11.0 and 12,0) in examples\ble_peripheral\ble_app_hrs_freertos. To keep the example clean, I made a copy of it and named the copy ble_app_hrs_freertos_sysview, where I will work."

     When you are installing SystemView, it normally asks the path where to install it, you will find these files in those chosen installation path.

    On my Windows system it is as below

     You need to copy mentioned files from here  to your project folder

    This is under  C:\Program Files\SEGGER\SystemView\Src\Config for me and yes, you need to copy this to your project folder

    Thanks for the response. 

    Though my folder structure looks different than yours. Why is that so?
