The HummingBoard Gate and Edge models feature a MIPI CSI connector onboard and both models support OV5640/OV5642 camera sensors. For more information on the implementation please see the schematics here.
Installing the cable incorrectly on the HB Edge/Gate can result in the Camera module being damaged!
The compatible cameras can be found in the following article: http://linuxgizmos.com/wandboard-sbc-gains-camera-add-ons/
Below are the device tree changes we used successfully to enable support for the OV5642 cameras.
