I just tried to get the CSI interface of the 53QSB to work:
First I load the modules:
> modprobe mxc_v4l2_capture
> modprobe ov3640_camera
But when I try to access these driver with the supplied test utilities
(mxc_v4l2_overlay.out, mxc_v4l2_capture.out) I always get error messages like these:
ERROR: v4l2 capture: slave not found!
Unable to open /dev/video0
I figured out that the probe method of the ov3640 is also not called (after modprobe).
For the test I used L2.6.35_11.01.00_ER.
When I use the same kernel&rootfs with the IMX51EVK everything works well.
So I guess it's something board/processor specific.
