I'm trying to do a head-to-head comparison between running some OpenCV video capture code on the Wandboard and another embedded linux board, and I'd like to use the same Leopard Imaging module (LI-5M03, schematic here:
http://processors.wiki.ti.com/images/7/78/Li-5m03_camera_board_v2.pdf) with both boards.

Has anyone connected the LI 34-pin interface to the Wandboard before? Any advice or sources for adapters/breakouts etc?

the camera you refer to is a parallel camera whereas the wandboard provides a MIPI interface.

you will have to find a MIPI interface camera for the wandboard.

There are 3 suppliers that either launched or about to launch a camera for the wandboard based on the OV5640 sensor.

Thanks for the advice. I've got one of the OV5640-based cameras on order and now I'm trying to setup my linux environment using yocto.

I've been able to assemble most of the packages I need; however, I haven't been able to get python-opencv (the cv2 python bindings for opencv) installed. I've tried installing via my bitbake recipe, using "pip" and using opkg but I haven't had any luck.  It appears that opencv_2.4.bb skips python-opencv, pip is unable to find the  opencv package, and opkg is apparently configured with no compatible feeds by default so is unable to find python-opencv.  I've also tried poking at the smart package manager but I can't seem to get it to do anything.

Any advice on which package manager I'm likely to have more success with?  I'm hoping to avoid installing android or ubuntu.

In case it helps anyone else, I ended up using opkg (with ipk package files) with my yocto build. I add a number of packages to the rootfs during the yocto build, and then I keep a separate repo of ipk files on my (ubuntu linux) build machine, which I can then access with opkg, via http, from the wandboard. This allows me to quickly rebuild on the fast build machine and then pull the packages down to the wandboard using opkg update.
