IWR1642BOOST: Error Running Lab Visualizer for People Counting

IWR1642BOOST: People Counting Demo unsuccessful reading of the config file

Cameron Haupt

Part Number: IWR1642BOOST

Hello all,

When attempting to run the pplcount_gui.exe, I receive the following output from the terminal window. The gui will exit after attempting to read the file.

I was able to successfully flash the lab onto the EVM.

I've found the issue in the forums, but there doesn't appear to be a solution yet. 

I'm new to working with the mmWave sensor, and any guidance would be appreciated. 

Opening configuration file C:\ti\mmwave_industrial_toolbox_2_3_1\labs\lab0011-pplcount\lab0011_pplcount_gui\mmw_pplcount_demo_default.cfg ...
Sending configuration from C:\ti\mmwave_industrial_toolbox_2_3_1\labs\lab0011-pplcount\lab0011_pplcount_gui\mmw_pplcount_demo_default.cfg file to IWR16xx ...

    Hi Cameron,

    We generally see this when the CLI does not initialize.  Can you connect to the UART COM Port with a program like Tera-Term - we want to see if the device gives CLI readout. If CLI is initialized, pressing enter (essentially sending a \n) should cause the device to give a new line with the prompt "mmwdemo>". 

    Please check to ensure that you put the device back in functional mode after flashing it.

    Regards,

    Justin

    Hey Justin,

    The resolution was that I didn't read the mmwave_sdk_user_guide well enough and I was not powering down the EVM before removing the SOP2 jumper to put it back into functional mode.

    As I said, I'm new to working with the sensor.

    I appreciate your quick response!

    Regards,

    Cameron
