Nitrogen 6X - can not get cameras operational.

Hi all,

 

I was directed to this mailing list by Igor from Freescale's community
forum. I have posted this issue there:
https://community.freescale.com/message/591641. Please take a look there for
a bit of context on my question.

 

In short, on a Nitrogen 6X board, running Ubuntu Trusty, with the
OV5640_MIPI and )V5640 parrallel cameras plugged in, if I write:

dmesg | grep video, I get:

mxc_hdmi 20e0000.hdmi_video: Detected HDMI controller 0x13:0xa:0xa0:0xc1

mxc_v4l2_output v4l2_out.35: V4L2 device registered as video16

mxc_v4l2_output v4l2_out.35: V4L2 device registered as video17

 

There is nothing about the cameras being registered as specific devices.
However, they are registered as /dev/video0 and /dev/video1. 

 

My question is: How can I programmatically determine which video device the
cameras are attached to?

Thank you very much in advance,

Kindest regards,
Cristian Pandele

There is a fix merged for jethro and master branch to address this.
