Thank you for the clarification. >> I need to read the entire RAW 12-bit grey value from the CCDC to >> memory and the data does not pass through other OMAP3ISP sub-devices. >> >> I intend to use Laurent's yavta to capture the data to file to verify >> its operation for the moment. >> >> Can this 12-bit (Y12) raw capture be done? > > > Yes.

You need to set > up your media pipeline to do sensor->CCDC->OMAP3 ISP CCDC output. Is there further modification needed to apply to the OMAP3ISP to achieve this? Do you have an application to test the pipeline for this setting to simple display?
