= Introduction =
This article is for '''Yocto Project 1.2 - Poky 7.0.y denzil''' branch.<br>It is interesting read [[How to use the Yocto Project to develop Embedded Linux]] article previously.<br>
= 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].
$ git clone -b denzil git://git.isee.biz/pub/scm/poky.git
$ bitbake demo-image-sato
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.
= Extending the available packages with others layers =
You can append more layers to your environment in order to build more packages, in following wxample you'll download the meta-openembedded layer. In your poky directory
$ git clone -b denzil git://git.openembedded.org/meta-openembedded
&lt;path to&gt;/poky/meta-openembedded/meta-oe \
Now you can build any of the new packages added, for example:
$ bitbake postgresql
= Create your own Linux image =
