Hi !
I have start my BeagleboardXM Rev C by kernel 3.1.2
rootfs is Angstrom-Beagleboard-demo-image-glibc-ipk-2011.1-beagleboard.rootfs.tar.bz2
patched the following two patches for mt9p031 sensor
add support for mt9p031 sensor
luckly it can drive mt9p031 well
v4l-subvideo0~v4l-subvideo8 video0~video8 appears under /dev/
get media-ctl and yavta from http://git.ideasonboard.org/media-ctl.git and http://git.ideasonboard.org/yavta.git
cross-compile them with angstrom tools successfully and move them to rootfs
but I can't use media-ctl and yavta get YUYV image data
the following serial output
root@beagleboard:~# media-ctl -v -r -l '"mt9p031 2-0048":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":2->"OMAP3 ISP preview":0[1], "OMAP3 ISP preview":1->"OMAP3 ISP resizer":0[1], "OMAP3 ISP resizer":1->"OMAP3 ISP resizer output": 0[1]'
