IWR6843AOPEVM: Area Scanner Demo is giving a lot of skipped frames and then causing the playback to just hang after a bit.

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843LEVM

Hi,

I have been trying to test and collect some data using the Area Scanner Lab with both the IWR6843AOPEVM and the IWR6843LEVM.  In my tests as I try to record real-time data I see the following errors.  

When I try to playback the data it just just get stuck at some point and does not continue to play.

Please advise as I need this resolved before I can move to the next part of my design.

Regards.

    Hello Adib,

    The fastest work around for this is to go to the .txt output/playback file and remove the frames with issues. Once removed you will no longer have playback get stuck. If you are familiar with MATLAB, we provide the source code and you could go to the playback section of code and have it skip problematic frames. getFrameHeader.h will always be able to tell you when there is a frame issue, but currently there is a bug where the frame isn't actually skipped in playback mode.

    Best Regards,

    Thanks Pedrhom.  Is this a common issue?  I will use your workaround for now.  Are there any plans to fix the bug?  Thanks also for the pointer on where to look at in Matlab.

    Hello Adib,

    As the bug currently only affects playback mode and has an identified workaround, it is currently low priority. If this is a feature you are planning to use a lot and have a MATLAB license and experience, then I would suggest editing the playback feature and then recompile the source. That or script the removal of bad frames from txt files post recording rather than doing it manually.

    Best Regards,
