About this Section
This section addresses advanced developers who want to configure, build and install a new
kernel and file system, design custom expansion boards, or display adapters. It includes
the following information:
Step by step instructions on how to configure, build and install a new kernel and file
system using the virtual machine
A description how to update the Bootloader and how to write the Kernel and Root File
System into the Flash
Detailed information on the different interfaces and features of the phyBOARD-Wega at
a system level
How to set up your own Linux host PC

Software Overview
In
chapter 2
you have learned how to work with
Eclipse
and
Qt Creator
. The following
section shows how to work with the
Yocto Project
.
The
Yocto Project
is an open source collaboration project. The build system used by the
Yocto Project is based on the
OpenEmbedded
Project. With this build system you can
construct complete linux images for different platforms and architectures. The
Yocto
Project
includes components to design, develop, build, debug, simulate and test your
software.

Getting Started with the BSP
In this chapter you will go through some software topics. First of all we take a look at the BSP
and learn how to add a package. After compiling the new images, you will learn how to write
the newly created kernel and root file system into the target’s flash memory and how to start
the images.
4.3.1
Working with Yocto
In this chapter of the Application Guide we describe only the basic
Yocto
usage. For in-depth explanations refer to the
Yocto
Reference Manual.
In this part you will learn how to use the
Yocto Project
and the Phytec BSP. You can find the
pre-build BSP in the virtual machine under
/opt/PHYTEC_BSPs/phyBOARD-WEGA/
. All
necessary tools and programs are already pre-installed to directly start with
Yocto
.
