i.MX6ULL-EVK with OV5640

------------------------



On this platform a parallel OV5640 sensor is connected to the CSI port.

The following example configures a video capture pipeline with an output

of 640x480 and UYVY8_2X8 format:



.. code-block:: none



   # Setup links

   media-ctl -l "'ov5640 1-003c':0 -> 'csi':0[1]"

   media-ctl -l "'csi':1 -> 'csi capture':0[1]"



   # Configure pads for pipeline

   media-ctl -v -V "'ov5640 1-003c':0 [fmt:UYVY8_2X8/640x480 field:none]"



After this streaming can start:



.. code-block:: none



   gst-launch-1.0 -v v4l2src device=/dev/video1 ! video/x-raw,format=UYVY,width=640,height=480 ! v4l2convert ! fbdevsink



.. code-block:: none
