How to use OV5640 with i.MX 6UltraLite EVK

less than 1 minute read

The i.MX 6UltraLite EVK kernel release includes the parallel camera OV5640 support by default. However, depending on the base board revision, this camera might requires the SCH700-27820 adapter below:

According to the following image, the FX12B-40P-0.4SV connector layout was changed in the RevC, giving the possibility to use the OV5640 directly:

RevB vs RevC camera layout
Rev B in the left and Rev C in the right, which does not need the adapter

So if you are using a base board older than Rev C, plug in the camera with the adapter and connect the other end of the adapter to the board:

In order to use the parallel OV5640 camera, it’s necessary to set up the environment variable below on U-Boot, independent of the base board revision:

=> setenv fdt_file ‘imx6ul-14x14-evk-csi.dtb’
=> saveenv

Follow the GStreamer pipeline example to test the camera connection:

$ gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=640,height=480 ! autovideosink
Camera test
RevB with adapter camera test

RevC directly camera test

This test was done using the kernel BSP release 4.1.15-2.0.0 GA.
