Hi All,

The HW/SW version environment as bellow:

Linux kernel :L3.0.35_4.1.0_130816

Demo rootfs : Ubuntu Image download from freescale website.

Device: i.MX 6Quad SABRE board

I am trying launch camera application on Ubuntu, for instance skype.

But mxc_v4l2_caputre can't open /dev/video1.

Camera driver has been tested by using gstreamer (gst-launch mfw_v4lsrc device=/dev/video0  ! mfw_v4lsink) and test tools ( /unit_test/mxc_v4l2_overlay).

It works fine.

Please help or any clue. thanks in advance.

Hello Jimmy,

Can you take a look at the following thread?:

v4l2 capture: slave not found!

I think you can solve it the same way as that thread...
