You can download the compiled images from here: *IGEP Board with TVP5151 peripheral (IGEPv2 Expansion Board or IGEP Berlin).*Camera with PAL output live video.*IGEP SDK (IGEP VM suggested).

= TVP5151 Setup<br> = You need the program [http://downloads.isee.biz/pub/files/tvp5151/2.6.35/media-ctl media-ctl] this program it's useful for configure the ISP.<br> There are two modules that you will use that are not inserted into the kernel: iommu2 *Connect a video composite input to J501 connector from IGEPv2 Expansion (
tvp5151near CAN Bus)
and isp. You have to load these kernel modules before start:<br> <pre>modprobe iommu2modprobe omap3-isp</pre> or J402 connector from IGEP BERLIN (
Note: The first load order must be the iommu2 and then the omap3-ispnear HDMI output)
