First we have to create directory where to setup an environment. My choise is /angstrom in root directory, but you are free to use whatever you want
Code: Select all
mkdir /angstrom

We have to change owner of directory – all other commands have to be executed as non root user. In this case I’ll use user named user
Code: Select all
chown user.user /angstrom

Now login as non root user:
Code: Select all
su – user

Building Ångström includes a setup script - go to the the setup-scripts repository and clone it, the URLS are on top of that page. You should end up doing something like:
Code: Select all
git clone git:// /angstrom

Next step is to define our target machine and start updating process
Code: Select all
cd /angstrom
MACHINE=cs-e9302 ./ update

After executing of script – OpenEmbedded and BitBake will be obtained. Also script creates a environment file with all needed path variables. This file is stored in user home directory. It’s recommended to execute this in user profile. Edit file ~/.bashrc.
Code: Select all
nano ~/.bashrc

and add following line in the end of file:
Code: Select all
. ~/.oe/environment-2008

Restart your terminal. Check if everything is fine by typing:
Code: Select all
bitbake --version

You should see something like
Code: Select all
BitBake Build Tool Core version 1.12.0, bitbake version 1.12.0

To complete process we have to run first building of package(image) using the Angstrom script. I choose to build nano package
Code: Select all
MACHINE=cs-e9302 ./ bitbake nano

After a wait we already have the basic structure. It should looks like listing shown below:
Code: Select all
user@ubuntu:~$ ls -al /angstrom/
total 40
