This guide explains building the Embedded Linux distribution - Angstrom from source in a beginner friendly manner.

Important Notes

1. These instructions have been documented using Ubuntu 12.04 LTS as the reference operating system. It is advised that you also have the same setup.

2. Please make sure that you have at least 18GB of free space available as the source code can take up a lot of space.

3. It took 8 hours to build a systemd-image on a dual core I7 machine with 8GB RAM and only two(out of the possible 4) threads used.



Install the pre-requisites by typing the command below in the terminal:

sudo apt-get install gawk wget git diffstat unzip build-essential chrpath libsdl1.2-dev xterm unzip texinfo \
git texi2html subversion ncurses-dev sed cvs coreutils docbook-utils python-pysqlite2 help2man make \
gcc g++ desktop-file-utils chrpath dosfstools kpartx bitbake


Change the default shell in Ubuntu from dash to bash typing the command below in the terminal::

sudo dpkg-reconfigure bash


The next step is to download the Angstrom setup scripts which will help us prepare a development environment for building the Angstrom image. Type the following command in your terminal:

git clone git://github.com/Angstrom-distribution/setup-scripts.git


Make the necessary changes to the local.conf file as shown below. This file can be found in ~/setup-scripts/conf/local.conf .

# Add this to the bottom:
MACHINE ?= "minnow"
LICENSE_FLAGS_WHITELIST = "license_emgd-driver-bin commercial" 
NOISO = "1"
* LICENSE_FLAGS_WHITELIST = "license_emgd-driver-bin commercial" is required to prevent the resulting image from including 
  anything that might violate the license terms of the packages used to implement the video acceleration feature, such as 
  gst-ffmpeg and ffmpeg.


Setup the necessary environment for MinnowBoard by typing the command below in the terminal:

MACHINE=minnow ./oebb.sh config minnow


Build the image by typing the following command in the terminal:

MACHINE=minnow ./oebb.sh bitbake systemd-image


The resulting image will be located in ~/setup-scripts/build/tmp-angstrom_v2012_12-eglibc/deploy/images/minnow/

Writing the Angstrom Image to an external storage device
