Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: IWR6843

Hi,

I'm trying to run 3D pplcount demo on IWR6843ISK-ODS. I followed the user guide, but at the 4th step "Run the Lab", there was no reaction when I clicked the "Select configuration" button, which is show in the figure below. I also ran gui_main.py at command line. The 2nd figure shows the hint when I clicking the button. Could you please do me a favor by giving some suggestions about how to address this problem?

Regards,

Jie

    Hello

    Please see if changing to 32bit Python version helps.  This is called out at a requirement for Gui as listed in User's guide.

    Hi Jie,

    Where is your directory located? I believe you have found a bug. Can you try the following for a temporary fix?

    1. Create a folder in your machine, "C/ti/

    2. Put the mmwave toolbox in that directory

    a. The toolbox should have an address like: C:\ti\mmwave_industrial_toolbox_4_3_2

    Now try running the GUI.

    The issue is the gui does a search for the directory where the chirp configs are located (this won't be known if you use the installed version). The search specifically looks in C:\ti\mmwave_industrial_toolbox.... so if you do not have the toolbox installed there, the gui will have issues.

    Regards,

    Hi Justin,

    Thanks for your quick reply!

    You are right. This problem has been solved after creating a folder following what you said or changing the path in gui_main.py. But after clicking "Send Configuration", the user interface became no response again. The command line displayed many " b'' ", which is shown below.

    Hi Jie,

    After each command is sent from the GUI, it waits for a response. This shows that there is no response coming from the device. Usually this is because the IWR6843 device is in flashing mode, instead of functional mode. Make sure you have the device in the right mode and reset it.

    Dear Justin, 

    Thanks for your quick reply!

    Thanks to your guidance, the demo can run successfully ：）. The problem occured because I forgot to power cycle the EVM with SW2 after removing SOP2 jumper.
