Build Platform Setup Environment

In order to build an image with BSP support for a given release, you need to download the corresponding BSP repository. At this time latest stable branch for IGEP devices is denzil. 

 $ git clone -b denzil git://git.isee.biz/pub/scm/poky.git

Enter to the poky directory, 

 $ cd poky

and clone the meta-isee layer. 

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

 $ source oe-init-build-env

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-igep' layer to 'bblayers.conf'

Add below line into .../poky/build/conf/bblayers.conf: 

       <path to>/poky/meta-isee \

To enable the isee layer, add the 'igep00x0 MACHINE' to .../poky/build/conf/local.conf: 

 MACHINE ?= "igep00x0"

You should then be able to build a image as such: 

 $ 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

Add the layer into build/conf/bblayers.conf: 

       <path to>/poky/meta-openembedded/meta-oe \

Now you can build any of the new packages added, for example: 

 $ bitbake postgresql

Create your own Linux image
