= Introduction =

This article describes how to install and build the Yocto Linux 1.6 (Daisy) release for CM-T43 SOM on a development machine.

= Preparation steps =

* Obtain Linux PC host development station running '''''Ubuntu 12.04 64 LTS'''''.
* Download the Linux Yocto package for CM-T43 from [http://compulab.co.il/products/computer-on-modules/cm-t43/#devres CompuLab website]. Unzip the package to a directory on your host workstation:
<pre>
mkdir cm-t43-yocto-dev
cd cm-t43-yocto-dev
unzip /path/to/downloaded/cm-t43-yocto-linux.zip
</pre>
* Install development tools:
<pre>
sudo apt-get install git build-essential diffstat texinfo gawk chrpath gcc-multilib wget socat libsdl1.2-dev ia32-libs mtd-utils
</pre>
* Install the Arago toolchain
<pre>
wget --no-check-certificate https://launchpad.net/linaro-toolchain-binaries/trunk/2013.03/+download/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux.tar.bz2
sudo tar -jxvf gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux.tar.bz2 -C /opt
</pre>

== Download and install Yocto Linux development source code ==

Type the following commands to download and install the Yocto 1.6 (Daisy) Linux source code on the development station:
<pre>
git clone git://arago-project.org/git/projects/oe-layersetup.git tisdk
cd tisdk
./oe-layertool-setup.sh -f ../cm-t43-yocto-linux/development/config-yocto-1.6-cm-t43-1.txt
</pre>

=== Apply the CM-T43 support patch ===
Once the Yocto 1.6 (Daisy) Linux source code is installed on the Host Ubuntu machine, apply the CM-T43 patch, as follows:
<pre>
patch -p1 < ../cm-t43-yocto-linux/development/yocto-1.6-cm-t43-1.patch
</pre>
At this point, CompuLab Yocto support has been installed over the Yocto Linux source code and can be built.

== local.conf customizations ==
For local builds customization, edit you local.conf file with any favourite text editor.

=== Parallel build ===
Set the build parameters to fully utilize your host machine
BB_NUMBER_THREADS = '4'<br>PARALLEL_MAKE = '-j 6'
BB_NUMBER_THREADS should be your host machine's number of threads minus 2 or same.
PARALLEL_MAKE should be the number of threads your host machine has plus two.<br>

=== Download directory ===
Recommended to save download time and space.
DL_DIR = "/home/<uname>/yocto_dl"<br>

== Setting up the Toolchain ==
<pre>
export PATH=/opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/bin:$PATH
</pre>

= Building the CM-T43 Yocto image =
Change directory to the build directory of Yocto and set up the build environment:
<pre>
cd build
source conf/setenv
</pre>

The {{parameter|tisdk-rootfs-image}} can be built as follows:
<pre>
MACHINE=cm-t43 bitbake tisdk-rootfs-image
</pre>

After the image is built, all images are located in: {{filename|/path/to/cm-t43-yocto-dev/tisdk/build/arago-tmp-external-linaro-toolchain/deploy/images/cm-t43}}
