Original question:

IWR1642BOOST: mmWave Demo Visualizer: failure in PC-board connection. Waiting for data

AWR1642BOOST: mmWave Demo Visualizer: failure in PC-board connection. Waiting for data

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642, UNIFLASH, MMWAVE-SDK

I am attempting to run the Demo Visualizer example and I cannot get Demo visualizer to connect to the AWR1642 BOOST EVM board. I've tried using the web app on Chrome/Firefox on Linux and Win10 and using the offline Demo Visualizer. I believe I've set up the COM ports and TTYACM0 ports correctly. I even downloaded minicom in Ubuntu, connected it to ttyACM0 and pressed 'enter' as suggested in another post and it returned "mmwDemo :/>" indicating the demo was flashed properly. I also tried reflashing the Demo binary with Uniflash.

Here is a screen shot of the connection issue:

Sometimes this area just says "Connecting to Target" but never connects.

In the serial port configuration page, the program can select the correct ports.

What am I missing here? What steps should I take to troubleshoot this issue.

    Hello Lindsay,

    Looking at the screenshot it looks like the mmwave demo visualizer is connected to the ports of the EVM and is waiting for the data. If you have the OOB demo running on the EVM you can send the configuration from the visualizer and then get the data object data over UART from the device.

    Please refer to the MMWAVE-SDK userguide on how to download and execute the OOB demo.

    Thanks,

    This seems to have worked after a few attempts. The Demo runs reliably now. I think the trick was to press the reset button on the board after the first waiting to connect message. After this, the configuration upload goes through and starts the demo.

    I still run into a similar connection type problem when performing other labs from the SDK. I'll open it as a separate question though. Thanks!
