No CSI data received from raw sensor

Thanks Shane,

But this is not camera image CSI frame, so I can’t convert it to any other format.
This is automotive radar ADC samples passed over CSI.

When saving to file with v4l2-ctl, and then opening the file with Python openCV, I can see the data is correct and valid.

Is there any solution to read the data frame-by-frame from openCV with nvarguscamerasrc or v4l2-ctl ?

Thanks,
Ron
