I have switched my hardware from the SabreSD Board w/ i.MX6Q to SabreSD Platform w/ i.MX6Q.
I am using ltib from L3.0.35_4.0.0_ER_SOURCE.tar.gz to build my kernel and rootfs from scratch.
I used the same SD card with the same rootfs/bootloader/kernel that I was using to boot the SabreSD Board and used it to boot the SabreSD Platform. Everything went fine except now I am trying to get video from the ov5640 MIPI camera using the pipeline "gst-launch mfw_v4lsrc ! mfw_v4lsink" and I get the following output on my dmesg:
camera ov5640_mipi is found
ERROR: v4l2 capture: slave not found!
Of course I have modprobed the drivers; my lsmod shows:
Module Size Used by

ipu_bg_overlay_sdc 3925 1 mxc_v4l2_capture

camera_sensor_clock 765 1 ov5640_camera_mipi
I checked the file sizes of L3.0.35_4.0.0_ER_SOURCE and L3.0.35_4.0.0_DEMO_IMAGE under
Freescale > i.MX Applications Processors >i.MX 6 Series Processors > RDIMX6SABREPLAT (for SabreSD Platform) and under Freescale > i.MX Applications Processors > i.MX 6 Series Processors > RDIMX6SABREBRD (for SabreSD Board) and found the file sizes to be exactly the same same. Also, I found nothing in the kernel config or ltib config specifically referring to the SabreSD Platform. To the best of my knowledge, SabreSD Board is just a stripped down version of the SabreSD Platform.
So my question is, does the SabreSD Platform and SabreSD Board share the same SDK? And what is causing the ERROR: v4l2 capture: slave not found! message?
