TDA3MV: Identification of captured consecutive frames with having the same CRC (identical frames)

$

Part Number:TDA3MV

Hello,

I am using an own and lightweight CSI-2 capture driver to recieve frames from the UB954 deserializer. The driver is working good and there is also an CRC-error interrupt implemented.

But I need to identify incoming identical frames without an CRC-error. It could also happend, if there is an unknown error and the capture driver fakes a new frame. This is a safety feature requested from the customer.

Is there a way to read the CRC from the CSI-2 stream (packet footer)? Or is there another solution to identify identical frames?

Best regards,
Milan
