$ = Build Platform Setup Environment = {{Message/Information Message|message= '''The instructions below are only for IGEP PROCESSOR BOARDS based on OMAP3 processor.'''}}  In order to build an image with BSP support for a given release, you need to download the corresponding BSP repository. <br> At this time latest stable branch for IGEP devices is [http://git.isee.biz/?p=pub/scm/poky.git;a=shortlog;h=refs/heads/denzil denzil].  <pre>git clone -b denzil git://git.isee.biz/pub/scm/poky.git</pre>

$ <pre>cd poky</pre>

and clone the [http://git.isee.biz/?p=pub/scm/meta-isee.git;a=shortlog;h=refs/heads/denzil meta-isee ] layer.

$ <pre>git clone -b denzil git://git.isee.biz/pub/scm/meta-isee.git</pre>

$ <pre>source oe-init-build-env</pre>

Having done that, and assuming you downloaded the BSP contents at the top-level of your yocto build tree, you can build a igep image by adding the location of the 'meta-igepisee' layer to 'bblayers.conf'

$ <pre>bitbake demo-image-sato</pre>

At the end of a successful build, you should have an image that you could use for boot device from flash or a micro-SD card. or you can create the installable firmware using:
