This is a guide for creating a Yocto linux image on Ubuntu 12.04.
h2. Prepare the Environment
* Make sure the system is up to date:
<pre>
sudo apt-get update && sudo apt-get upgade
</pre>
* Install a few prerequisite packages:
<pre>
sudo apt-get install apt-get install gawk wget git bitbake diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm parted
</pre>
h2. Download the Source Code
* Create a directory for the source code:
<pre>
mkdir ~/git && cd ~/git
</pre>
* Get the latest IoT Yocto Development Kit:
<pre>
git clone -b devkit-daisy git://git.yoctoproject.org/meta-intel-iot-devkit iotdk
cd iotdk
</pre>
* Source the @iot-devkit-init-build-env@ script:
<pre>
source iot-devkit-init-build-env
</pre>
h2. Build the Yocto Image
* Run bitbake to build iot-devkit-image:
<pre>
bitbake iot-devkit-image
</pre>
#* *NOTE*: There are many types of image targets for bitbake to use, such as:
<pre>
iot-devkit-image
iot-devkit-prof-dev-image
iot-devkit-prof-image
iot-devkit-spi-image
</pre>
* Fix the grub bitbake source:
<pre>
nano ~/git/iotdk/meta-quark-bsp/recipes-bsp/grub/grub_0.97.bb
</pre>
#* And the SRC_URI to the following:
<pre>
SRC_URI = "git://github.com/intel-iot-devkit/grub-fedora.git"
</pre>
* (Optional) To use the Hob GUI to assist in building, run:
<pre>
bitbake -u hob
</pre>
h3. Deploy the Yocto Image
* Use wic to create a bootable micro SD image:
<pre>
~/git/iotdk/scripts/wic create -e iot-devkit-image ~/git/iotdk/scripts/lib/image/canned-wks/iot-devkit.wks
</pre>
* Write the image using dd:
<pre>
sudo dd if=/var/tmp/wic/build/iot-devkit-201506161028-mmcblkp0.direct of=/dev/mmcblk0 bs=1M
sudo sync
</pre>
*NOTE*: Make sure to update the timestamp for the image in @/var/tmp/wic/build/@
