Hi Bastian, As Laurent poonted out, the DM3730 doesn't support CSI2. This is really unfortunate as many sensors tend to use that interface nowadays. I wonder if there would be alternative sensors available that would use parallel interface instead. On the other hand, then you can't receive two streams simultaneously using a single OMAP without special arrangements. If interleaved exposure start is out of question you'll need more than one OMAP. :I Or somehow get OMAP 36x0s. They do have dual CSI2 receivers. To the latter question: I don't think the CSI2 protocol has any issues with this kind of use.
