AWR1243BOOST: frame data sometimes corrupt (sudden value change)

Hayden Kim

Part Number: AWR1243BOOST

While doing test with AWR1243BOOST EVM, there was an issue with captured data as below description.

* Symptom is that bit value suddenly changed (discontinuity) in the frame of captured ADC data
* When object is static, the data (sudden) change issue did not happen
* The issue happens sometimes (3~4 per 100 frames), when object is moving
* When issue happened, in the frame (one frame -> 512 ADC samples per chirp, 128 captured data), there was data change (discontinuity) at certain point
* Normal case, there is no (significant) bit data change in the frame

So, can you guess what kind of issue, and why the issue happens?

Thanks and regards,

Hello Hayden,
As discussed over email this seems like a data capture issue. Can they try using the internal test source that would emulate an ideal object to verify the data interface?

Vivek

Hello Vivek,

He will check the interface with the test mode as you guided.
If there is more issue or any update, I will post again.

Thanks and regards,
Hayden
