Embedded Linux: Building a System from the Ground Up Training Course

Buildroot is an open-source project that contains scripts that produce a cross-compilation toolchain, a customizable root filesystem image, and a Linux kernel for embedded devices. During this practical course, participants will learn how to use it:

• How to select software that goes into the root filesystem.
• How to add new packages and modify existing ones.
• How to add support for new embedded boards.

During the course, bootable filesystem images will be produced. Remote courses are delivered using the QEMU emulator, while in the classroom it is possible to use either QEMU or real embedded boards of the trainer's choice.

Other projects with similar goals include the Yocto project and OpenWRT. Please use these presentations to determine which one is the right choice for your needs.

The LEDE Project (Linux Embedded Development Environment) is a Linux operating system based on OpenWrt. It is a complete replacement for the vendor-supplied firmware of a wide range of wireless routers and non-network devices.

In this instructor-led, live training in Costa Rica, participants will learn how to create a build system for embedded Linux based on Yocto Project.

By the end of this training, participants will be able to:

• Understand the fundamental concepts behind a Yocto Project build system, including recipes, metadata, and layers.
• Build a Linux image and run it under emulation.
• Save time and energy building embedded Linux systems.

Description

This four day training combines theory with hands-on exercises in order to introduce the Yocto Project.
It answers frequently asked questions like:

• Is it really necessary to use another version of the toolchain/libraries/packages for each and every GNU/Linux project and an top of that to follow a different work-flow?
• Can you ensure that the development environment is identical for all developers/suppliers and that you can still produce identical builds like today in 10+ years from now?
• Can the YP help find out under what software licenses the packages you use are licensed?

Hands-on sessions are performed on target hardware (e.g. Beagle Bone Black Rev. C - http://beagleboard.org/BLACK). After the training you will be able to download a docker image with Ubuntu 14.x and all dependencies pre-installed plus the examples in order to work with the course material in your own labs. Please note that this is not an introductory course to Embedded GNU/Linux. You should already know how Embedded GNU/Linux works and how to configure/build the GNU/Linux kernel and kernel drivers.

Who should attend?

You already use GNU/Linux for your projects and have probably heard about the Yocto Project, but did not dare to have a closer look into it, or had difficulties using it. You don’t know whether and how your daily work-flow can be accommodated in the YP and generally find the YP rather complicated. Why do we need all this since up to know everything was (supposedly) much easier? After the training you should be able to decide whether you need the YP or not. The workshop is aimed at software-, development-, system engineers, testers, administrators, engineers and other parties interested in the YP, with a solid knowledge of Embedded GNU/Linux.

Course Objectives

To provide an understanding of the essentials of embedded GNU/Linux, how the bits and pieces fit together. What components are needed to build an embedded GNU/Linux system, where to get them from and how to configure/build/install them? Where to get help from? What about those software licenses? Hands-on exercises provide you with the necessary practical experience to go ahead and develop your own embedded GNU/Linux systems after completing this training successfully.

Description

This five day training class uses hands-on exercises combined with instruction to illustrate the concepts of embedded GNU/Linux. It is designed to bring you quickly up to speed. The philosophy, concepts and commands necessary to make effective use of GNU/Linux are described through a combination of theory and on-the-job training.

Don't reinvent the wheel, but learn from an experienced trainer and take home a working knowledge of GNU/Linux and the ability to use it effectively in your own embedded development project.

Who should attend?

Managers, project managers, software-, hardware-, development-, systems engineers, testers, administrators, technicians and other parties interested in the technology, who want to understand as quickly as possible how Embedded GNU/Linux works. You must use GNU/Linux or you have to luxury to decide whether it makes sense to use it or not. Maybe you already tried to use Embedded GNU/Linux, but are not quite sure that you did everything the right way. You currently use a different operating system and wand to figure out whether GNU/Linux might better and/or cheaper.

Delivery Options

All the training material is English, but the presentation of it can be in English or in German, as you wish, worldwide.

• on-site - instructor driven
• on-line - instructor driven
• on-site/on-line combination - instructor driven

A two day course consisting of around 60% hands-on labs focusing on Embedded Linux kernel internals, architecture, development and investigating how to write and integrate several types of device drivers.

Who should attend?

Engineers interested in Linux kernel development on Embedded systems and plateforms.

This is a two day course covering all basic principles of building Embedded linux Systems, around 60% of the entire course time is practical hands-on implementation for real world application using the same standards and tools used in industry

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.

Description

This 5-day training class uses hands-on exercises combined with instruction to illustrate the concepts of GNU/Linux kernel internals and device driver development. It is desinged to bring you quickly up to speed. We describe processes, concepts and commands necessary to write GNU/Linux device drivers through a combination of theory and on-the-job training.

Don't reinvent the wheel, but learn from an experienced trainer and take home a working knowledge and the ability to use it effectively in your own embedded development project.

Who should attend?

People with interest in or tasked with the development or evaluation of developing GNU/Linux device drivers like software engineers, field engineers, (project) managers, hardware engineers.

An ARM processor is one of a family of CPUs based on the RISC (reduced instruction set computer) architecture developed by Advanced RISC Machines (ARM).

Berkeley DB (BDB) is a software library intended to provide a high-performance embedded database for key/value data. Berkeley DB is written in C with API bindings for C++, C#, Java, Perl, PHP, Python, Ruby, Smalltalk, Tcl, and many other programming languages. Berkeley DB is not a relational database.

This course will introduce the architecture and capabilities of Berkeley DB and walk participants through the development of their own sample application using Berkeley DB.
