I'm using the GUI of area scanner of the lab example. It used to work fine before but it suddenly stopped working and facing the below issue, could you let me know what is the issue and why is it sporadic?

While doing the test connection for area scanner lab example using the GUI, will the .bin file be affected which has been dumped into the hardware? or is this independent of that?

Hi Harish,

Thanks for reaching out to our team!

Do you have any other programs open that may be using the COM port? (ex: tera term windows, uniflash tool, online oob demo visualizer)

The .bin file you flashed the device with will not be affected by the lack of port response.

Thank you,

Angie

I have the online visualizer opened but not using to connect the hardware. This issue I'm facing alot but not sure about the exact reason behind it

Please also double check that your board is in functional mode.

Try closing the online visualizer, soft resetting the device (press the reset button on the board) and trying again.

If this does not work then (with the visualizer still closed), try to unplug your device from power and then plug it back in and connect to the gui again.

Thank you,

Angie

I tried all the above things, it is still not working.

Hi Harish,

Can you please share a screen capture of your device manager showing your COM ports with me? Also, a picture of the switches on your board.

Thank you,

Angie

The switches on the board is fine because it works sporadically. Also, the functional mode i have checked.

Hi Harish,

I was able to look at this thread and learn more about your setup: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1081453/iwr6843aop

Do you see this sporadic COM port issue when you flash the pre-made binary provided in the industrial toolbox?

Thank you,

Angie

The sporadic behavior is not found for pre-built binary given by TI I think.

If you could see this thread, https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1081453/iwr6843aop

Is the compilation the issue ?

Also, you mentioned that for test connection the binaries does not matter.

Harish,

Any binary that contains a BSS (radarss), MSS, and DSS image will flash but if the projects for the MSS and DSS are built out of order than the BSS and DSS can be missing from the final MSS image causing an error. More details as to how these all work together can be found by inspecting the .projspec files for the project.

I would recommend building your DSS project and then re-building your MSS project and then flashing the binary image.

Thank you,

Angie Mitchell
