Hello,
Does the rv1106 support dvp camera interface? How to add dvp camera to the board?
How to add dvp camera driver
Hi, everyone.
Recently, I have try to add dvp camera driver uing RV1106. This is my dts file : It does not work, Is anybody have some sugguestions?

Hello, we haven't tried porting a DVP camera on the Luckfox Pico before. However, based on our experience with porting CSI cameras, we can provide some suggestions. From the logs you provided, it seems that an error occurs when calling the ISP. We suggest disabling the rkcif_dvp_sditf, rkisp, and rkisp_vir0 nodes first to check if a /dev/videoX device can be registered. Then, use v4l2 tools to capture RAW images to verify if the camera can work properly, in order to rule out hardware issues.
