This article is for Yocto Project 1.4 - Poky 9.0.y dylan branch.
It is interesting read How to use the Yocto Project to develop Embedded Linux article previously.

Build Platform Setup Environment

Information.jpg The instructions below are only for IGEP PROCESSOR BOARDS based on AM335x processor.

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 of Yocto for AM335x devices is Poky 9.0.y dylan branch.

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

Enter to the poky directory,

 $ cd poky

Clone the meta-isee layer for dylan:

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

Load Poky environment variables:

 $ 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-isee' layer to 'bblayers.conf'

Add meta-isee layer into .../poky/build/conf/bblayers.conf:

	<path to>/poky/meta-isee \

To enable the isee layer, add the 'igep0033 MACHINE' to .../poky/build/conf/local.conf:

 MACHINE ?= "igep0033"

NOTE: If your host machine has multiple corer, you can speed-up the compilation process uncommenting the BB_NUMBER_THREADS and PARALLEL_MAKE variables from local.conf.

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

 $ bitbake demo-image-sato do-release-firmware

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 example you'll download the meta-openembedded layer. In your poky directory

 $ git clone -b dylan 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
