TIDEP-01012: AWR2243: cascading radar: mmWave Studio 3.0.0.7: Raw data file becomes half of expected size

Hi,

The hw team will review your question

There will be delays due to Summer holidays

thank you

Cesar

Hi Shibata-san, 

I am unable to replicate this issue with the default MIMO Lua configuration. I ran this scenario with the default 8Msps and the 22.5Msps rate you called out. Can you please attach the configuration and data capture script you used to replicate the problem?

Thank you,

-Randy

Hi Randy,

Thank you for your support on this.

We are not using lua script but GUI only.

Please refer SensorConfig.PNG and adc_data_test*.mmwave.json in attached .zip files for configuration.

Best regards,

-Shibata

Hi Shibta-san

I see the sensor configuration tab.

Can you also please describe the static config, data config and the full chirp profile index setup you are applying? I see there are 64 different chirp profiles created. Can you describe the complete setup? 

Thank you,

-Randy 

Hi Randy,

Please find attached screenshot, captured after reproducing the issue.

Console logs are also included.

Here are some additional information:

- Only SensorConfig is modified from default configuration

- The configuration for master and slaves are the same

- The chirp configuration for 64 chirps are the same

Thanks & Regards,

-Shibata

Hi Shibata-san, 

Thank you for the additional details and logs. I see some faults being detected after the framing has started. You mentioned "the chirp configuration for 64 chirps are the same", but the default MIMO example configuration only has 12 chirps profile indices. 

Can you show the configuration for the 64 chirp indices? I need to be able to replicate the entire setup on my own EVM to try to understand the problem. 

Thank you,

-Randy

Hi Randy,

Thanks  for your continuous support.

I will check and get back to you.

Best regards,
