IWR6843AOPEVM: Cannot connect to mmWave SDK 3.6.0

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: UNIFLASH

I am using the IWR6843AOPEVM board on a Windows 11 laptop and the TI mmWave SDK 3.6.0 cloud development suite. When I plug in the EVM to my computer with the USB connector, the SDK perpetually says "connecting to 1 of 2 targets..." and the popup menu at the bottom left says "waiting for data..." This seems to go on forever.

These are my settings in the SDK.

This is what my ports look like in Windows device manager.

I am not sure what is going wrong here.

    Hi,

    I believe I know the cause of the issue you are facing. There is currently a bug with the browser version of the mmWave Demo Visualizer that we are working to resolve. Please see this thread for help finding the offline version of the tool. 

    Best Regards,

    Hello,

    I downloaded mmWave Demo Visualizer to my computer. I am no longer using the browser. However, the exact same issue persists. It keeps saying "connecting to 1 of 2 targets..." in the bottom left corner. I am using the same settings that I was using on the web version.

    Could this be a hardware issue? I am unable to find a specific baud rate for COM3 and COM4 on the datasheet for the IWR6843AOPEVM. The datasheet also mentions something about using Uniflash to flash the EVM. Do I need to do this before connecting with the mmWave visualizer?

    Yes, the device must be flashed with the Out-of-Box (OOB) demo binary before connecting to the visualizer. Instructions for using Uniflash to flash the mmWave EVMs can be found here.

    I would highly recommend that you follow the steps outlined in the Out-of-Box Demo User Guide if you haven't done so already. The guide covers all steps required to run the OOB demo, including: configuring the EVM, flashing the demo binary, connecting to the visualizer and running the demo.

    Best Regards,
