Part Number: IWR6843
Other Parts Discussed in Thread: UNIFLASH,

hi,

i am trying to run people counting demo on mmwave icboost module along with iwr6843. but the visualizer crashes once i click the start button on the  visualizer. The ports are well connected. the board is flashed correctly using uniflash. i remove the sop2 jumper and power cycled the board but still getting the same error  again and again.

    Hi Dua,

    It looks like the device is not returning data.  Please use a utility like Tera Term to monitor the Data com port after the GUI crashes. (COM 5 from the video in your other thread - baud 921600). If the sensor is returning data, you should see random characters continuously coming over in tera term. Please make sure this is the case - otherwise we need to determine why the board is not sending data.

    Regards,

    Justin

    hi Justin,

    thanks for your reply. When I am running the test people counting demo then the UART AND DATA ports both are connected thats why I couldnot connect to tera term using either of UART and Data ports. I am able to run "Human falls and stances" test. it works properly. I guess the system is returning data. But only the people counting demo is not responding. please help me out in solving this problem.

    Hi Dua,

    You will have to close the Matlab connection to the device to connect with Tera Term to verify the data is coming across.  As the fall detection demo is a different one, I would like to verify that People Counting is working properly on the device before moving to debugging the visualizer.

    Regards,

    Justin
