+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

+
+.. code-block:: none

+
+ # 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
