[meta-freescale] What image should I build on the SabreLite?

Hi

I did the same as you on fsl-image-multimedia-full
Here's what i get:

Is it possible that my camera is dead? How can i make sure of that?
I managed to make it work once on fsl-image-gui (dora branch). I guess i will rebuild this one just to make sure the camera is still working fine.

I added the CONFIG_USB_AUDIO to the kernel and i now have a UAC2_Gadget appearing in alsamixer, but no element is showing up: This sound device does not have any controls.

While building from dizzy, I grabbed the latest 'fsl-machine-test'
from O.S.Systems CI server (master branch):

        http://ci.ossystems.com.br/public/fsl-community-bsp/master/389/x11/nitrogen6x/fsl-image-machine-test-nitrogen6x-20141102-389.rootfs.sdcard

This image has the same kernel version (g9f710da) as the head of
dizzy, and it came right up.

        root at nitrogen6x:~# cat /proc/version
        Linux version 3.10.17-1.0.1_ga+yocto+g9f710da (jenkins at builder) (gcc
version 4.9.1 (GCC) ) #1 SMP Sun Nov 2 13:37:00 UTC 2014
        root at nitrogen6x:~# dmesg | grep ov5642
        mxc_v4l2_master_attach: ipu0:/csi0 parallel attached ov5642:mxc_v4l2_cap0
        ov5642 1-003d: created sysfs entry for reading regs
        camera ov5642 is found

I did see some weirdness in the mode setting of /dev/fb0, but the
camera was functional, and I tested with a minimal gst-launch
command-line:

        root at nitrogen6x:~# gst-launch mfw_v4lsrc ! mfw_v4lsink

Regards,

Eric
