Segger SystemView FRDM-K64F

[waltermarchewka]

Hi all,

Just received my FRDM-K64F and i am trying to get the the Segger SystemView working. The OpenSDA is installed and the debug works fine.  I followed this guide:

Segger SystemView: Realtime Analysis and Visualization for FreeRTOS | MCU on Eclipse 

But it wont connect.  I am trying to run in debug mode.  Is that wrong?  Any ideas?  Thanks !

Hi Erich,

I guess i should have start with "i'm on a mac" lol.  I was able to get it working in Windows, however i'm still having trouble on my Mac.  I see this in the console, which leads to believe i have the openSDA set up correctly.  Whenever i run the SystemView and select the Target to start recording, i select USB, my target device, SWD and Auto detect. But i receive a "Could not connect".

Hi Walter,

Just to make sure:

a) you need a Segger J-Link or the J-Link firmware on the openSDA of the FRDM board

b) make sure you are using the same J-Link version both in KDS and the one used by Segger (mismatch of DLLs can have strange side effects). If you install the Segger software, it does ask you to update the version in KDS (use KDS v3.2.0)

c) Check if the RTT is properly initialized. You can do with the SEGGER RTT Viewer channel infos menu:

Here you have to see the SysView channels:

I have an example project for the FRDM-K64F on GitHub (mcuoneclipse/Examples/KDS/FRDM-K64F120M/FRDM-K64F_Demo at master · ErichStyger/mcuoneclipse · GitHub ) which uses the Segger RTT with SystemView. I have attached the project to this reply as well, so you can try that project.

I hope this helps,

Erich
