If you have the pcap, could you please attach it? I'm trying to figure out exactly how many bytes are actually available from the camera. I don't understand why the driver is trying to download 1536x1050 pixels...even after looking at the code.
One thing that I did realize is that the ICX285 sensors are progressive scan CCDs rather than interlaced like the rest of the DSI families use. This is handled in the code by only using the "odd" field and setting the "even" field to 0.
The user that added support for the DSI III cameras had the Color version, not the Pro...though I would expect this aspect to remain the same between those two.
