MIPI camera through IPU2

Question asked by Richard Woodham on Oct 5, 2017

Suppose I have a MIPI camera connected to my i.MX 6 board and I want to route the video signal through IPU2, what changes do I have to make to the device tree?

Do I have to make any other changes? e.g explicitly enable IPU2 clock?

As it stands, with the supplied device tree I can capture image data through IPU1.  However, all the changes I have made so far end up with:

Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0
ERROR: from element /GstPipeline:pipeline0/GstImxV4l2VideoSrc:imxv4l2videosrc0: Internal data flow error.
Additional debug info:
../../../../gstreamer-1.8.3/libs/gst/base/gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstImxV4l2VideoSrc:imxv4l2videosrc0:
streaming task paused, reason error (-5)
Execution ended after 0:00:10.097194002

As if something is not switched on or not configured correctly.
