WE observed that changing parameters while trying to ingest video on CSI 1, the trace log changes, but for CSI 3 it remains the same as above and there is no video dump.

Kindly assist.

Looks like NVCSI/VI didn’t receive any validate data from the MIPI bus.
Maybe confirm the port configuration then probe the signal.

Thanks
