Part Number: DCA1000EVM

Hi Team,

According to customer, the DCA1000EVM not working and want to know how to repair or it is possible to refund it.

Below are the details.

1. When received the EVM, it does work?

--> When I received it, it was working. But not now.

2. If yes, when was the last time you used the EVM when you encountered that it is not working?

--> I have used EVM successfully several times up to about 2 month ago. But not working now.

3. What is your test setup when the EVM did not work?

--> It was used to download the data from IWR8843ISK EVM (60 GHz mm-wave radar sensor). The setup is general, which means just connection with cable.

and powering by PC. That's it. No other specific ones.

4. Any helpful information to help us troubleshoot the EVM would be much appreciated.

--> I want to ask you to check the board and repair it if there is a problem.

Thank you and looking forward for your kind response.

Regards,

Maynard

Hello Maynard,

What do they mean by "not working"?

Is it not powering on? What is the Power supply rating they used?

or is it not able to capture data? If this is the case, can they send a screenshot of the error they're getting?

Ishita

HI, Maynard:

Can you confirm

1) xwr6843ISK EVM works by itself with SDK out-of-box demo

2) xwr6843ISK EVM does not work with DCA1000 for raw data capture

In that case, I would suggest you to follow the step-by-step instruction for raw data capture listed here. 0572.mmWave_sensor_raw_data_capture_using_DCA1000_xwr6843.pdf

And update us which step you see the problem.

Best,

Zigang

Hi Ishita,

I just received response from the customer that when DCA1000 EVM was Power On, main chip became too hot, and it did not work.

Also according to them, it was impossible to download the data.

Maynard

Do you just need me to confirm the hardware is broken, so you can go ahead with the refund/replacement process?

Best,

I am so disappointed with TI.

As you know, I have answered to your questions several times and informed that it did not work after heated.

Time over one month has elapsed, but TI still ask what happen in my board.

If you can see the board, you can know its status right away. And then you can know the next step.

However, the board is just in my hand without knowing its destination.

As I mentioned so may time, I have to measure some signal with its board. But no way.

Strongly speaking, I will send the board and I ask you to check it with stopping communication.

Please let me know the address which I send it to.

I am a TI customer, and purchased so many components and boards.

Hope to receive the address.

Hi Kim,

Sorry about the numerous questions but we need to understand how the board got damage and what the issue is that you are currently experiencing before making any suggestions on next steps. It is possible that we can resolve the problem without having to ship the board back and forth.

As previously requested, can you share a picture of the hardware setup and radar studio GUI pictures and output when the failure happens.

Thanks for you patience.

Hi Kim,

Thanks for sending the setup image and additional information. The E2E posts linked below shows other customers with similar issues that were able to resolve it by re-flashing the FPGA. Can you try this?
