IWR1642BOOST: COM port is lost during operation

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: UNIFLASH

Hi team,

I have a trouble using IWR1642BOOST.

Use DEMOvisualizer in the cloud and start up normally.

Data has also been acquired.

However, over time, the connection is suddenly lost and the following error is displayed:

"No Texas Instrument USB ports detected. Please check your USB connections."

I checked the COM port in the device manager of the PC, but it is the same as before the error occurred and I can find the set port.

I think that virus security software may have affected, and installing and DEMOvisializer on a PC instead of the cloud does not change the results.

Does DEMOvisualizer installed on the PC also connect to the Internet?

I do not know what is happening.

Can you give me some advice?

Best regards,

Tomoaki Yoshida

Hi Tomoaki,

Quick question, does your PC sleep/hibernates before this problem is observed.

If yes, could you try disabling it and let us know if the problem is still observed.

Thanks

Hi Yogesh-san,

Thank you for your reply.

No, my PC was not in sleep mode then.

Hi Yogesh-san,

We found that the frame rate setting has an effect.

The manual states that the frame rate should be <3fps in HeatMAP mode.

It seems that the COM port was frequently lost because it used it with default 10fps.

However, setting it below 3fps is not perfect.

First of all, if the frame rate is high, is it correct that the COM port cannot be found like this time?

The frame rate has been reduced, but is there any other measure?

Best regards,

Hi Tomoaki,

Frame rate should not cause COM port failure. I am unable to re-produce your issue.

Is it possible for you to try following lab:

This uses different matlab visualizer. Just wanted to narrow down if the issue is with visualizer, lab or your setup.

Thanks

Hi Pranav,

Could you also try a different lab and visualizer to narrow down the issue.

Thanks

hi Yogesh,

Initially, I found 2 com ports on device manager and I tried to flash the code using uniflash and code composer studio and I failed. Now I found that the ports are missed from device manager.
