    Use CX3 + OV5640 to capture image, but it is unstable on ARM platform.

      Hi All,

       

      I am using e-con systems CX3 + OV5640 to develop UVC camera application, recently. But I have some problems.

       

      When I connect to my embedded system (Firefly RK3399 Linux Xubuntu 16.04) using CX3 + OV5640 and setting camera resolutions at 1280x720 or 1920x1080 , that is unstable to capture (or streaming) frames, like this. But 640x480 is no problem.

      (the noise is random.)

       

      When I connect to Linux (x86) or Windows (x86) at 480, 720 or 1080, it has no problem, too.

       

      Why is this happening?

       

      ------

      Development Kit: Firefly RK3399

      Camera Kit: e-con systems CX3 + OV5640

      Library: OpenCV 3.4.0 or V4L2

      Regards,
