Introduction

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

NOTE: The instructions below are only for IGEP PROCESSOR BOARDS based on AM335x processor. CHOOSE YOUR BUILD SYSTEM BASED ON THE SUPPORTED PLATFORM

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 AM335x devices is dylan.

 $ git clone -b dylan git://git.yoctoproject.org/poky.git

Enter to the poky directory,

 $ cd poky

and clone the meta-igep layer.

 $ git clone https://github.com/ebutera/meta-igep.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-igep \

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

 MACHINE ?= "igep0033"

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

 $ bitbake core-image-minimal

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

Create your own rootfs image
