Want to capture raw imgage in Dragonboard 410c ( Linux Kernel) Camera Mezzanine Board + OV5640 Camera Module

Hi,
I have a Dragon board 410C (Debian Kernel) in it. I want to capture the raw image in Dragonboard 410c with Camera Mezzanine Board + OV5640 Camera Module.

Please can you help me on this.

This is a broad question, you should have a look at the camera wiki, there is also an interesting article here.
