Introduction to Embedded Linux (Hands-on training) Training Course

Buildroot is an open-source initiative providing scripts to generate a cross-compilation toolchain, a customizable root filesystem image, and a Linux kernel tailored for embedded devices. In this hands-on course, participants will learn how to utilize Buildroot to:

• Select the software components included in the root filesystem.
• Add new packages and modify existing ones.
• Integrate support for new embedded boards.

Throughout the course, participants will produce bootable filesystem images. Remote sessions utilize the QEMU emulator, while in-person classes allow for the use of either QEMU or real embedded boards chosen by the instructor.

Other projects with similar objectives include the Yocto Project and OpenWRT. Please consult these presentations to determine which tool best suits your requirements.

Course Objectives

This course aims to deepen your understanding of the fundamentals of embedded GNU/Linux, explaining how its components integrate. You will learn which parts are required to construct an embedded GNU/Linux system, their sources, and the methods for configuring, building, and installing them. Additionally, the course addresses where to seek support and clarifies software licensing issues. Through practical, hands-on exercises, you will gain the necessary experience to successfully develop your own embedded GNU/Linux systems upon completing this training.

Description

Over five days, this training class combines instructional theory with hands-on exercises to illustrate embedded GNU/Linux concepts. It is designed to accelerate your proficiency. The course covers the philosophy, core concepts, and essential commands needed to utilize GNU/Linux effectively, blending theoretical knowledge with practical application.

There is no need to reinvent the wheel; instead, learn from an experienced trainer and leave with a solid working knowledge of GNU/Linux, enabling you to apply it effectively in your own embedded development projects.

Who should attend?

This course is ideal for managers, project managers, software and hardware engineers, development and systems engineers, testers, administrators, technicians, and other interested parties who wish to quickly grasp how Embedded GNU/Linux operates. It is suitable for those who already use GNU/Linux or who need to decide if it is the right choice for their needs. If you have previously attempted to use Embedded GNU/Linux but are unsure of your methods, or if you currently use a different operating system and wish to evaluate whether GNU/Linux offers better or more cost-effective solutions, this course is for you.

Delivery Options

While all training materials are in English, the presentation can be conducted in either English or German, available worldwide.

• In-person instructor-led training
• Online instructor-led training
• Hybrid in-person/online instructor-led training

This two-day course features approximately 60% hands-on labs, concentrating on the internals and architecture of the Embedded Linux kernel, as well as development practices and techniques for writing and integrating various device drivers.

Target Audience

Engineers interested in developing for the Linux kernel on embedded systems and platforms.

In this instructor-led live training held in Brazil, participants will learn how to construct an embedded Linux system from the ground up. From compiling a minimal kernel to configuring boot and initialization processes, attendees will gain the necessary tools, techniques, and mindset to deploy a complete embedded Linux solution.

For remote sessions, QEMU will be used to emulate the hardware. Other platforms, including actual hardware devices, can be discussed individually.

Description

This 5-day training course combines practical exercises with instructional guidance to illustrate the key concepts of GNU/Linux kernel internals and device driver development. The curriculum is designed to accelerate your learning curve. Through a blend of theoretical foundation and hands-on practice, we cover the processes, concepts, and commands essential for writing GNU/Linux device drivers.

Don't reinvent the wheel; instead, learn from an experienced trainer to gain practical knowledge and the ability to apply it effectively in your own embedded development projects.

Who should attend?

This course is ideal for individuals interested in or responsible for developing or evaluating GNU/Linux device drivers, including software engineers, field engineers, (project) managers, and hardware engineers.

The LEDE Project (Linux Embedded Development Environment) is a Linux operating system derived from OpenWrt. It serves as a comprehensive alternative to the firmware provided by vendors for numerous wireless routers and non-network devices.

In this instructor-led live training, participants will acquire the skills necessary to configure a wireless router running LEDE.

Target Audience

• Network administrators and technicians

Course Format

• Combination of lectures, discussions, exercises, and extensive hands-on practice

This instructor-led live training in Brazil (online or onsite) is aimed at engineers who wish to implement NetApp ONTAP.

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

• Set up and administer ONTAP 9.3 Cluster (3 days).
• Safeguard data through Data Protection technologies (2 days).

In this instructor-led live training in Brazil, participants will learn how to create a build system for embedded Linux based on the 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 blends theoretical concepts with practical exercises to introduce participants to the Yocto Project.
It addresses common inquiries, such as:

• Is it truly necessary to employ a distinct version of the toolchain, libraries, or packages for every GNU/Linux project, alongside adhering to a different workflow?
• Can you guarantee that the development environment remains identical for all developers and suppliers, ensuring that builds produced today will remain reproducible in ten or more years?
• Can the YP assist in identifying the software licenses applicable to the packages you utilize?

Practical sessions are conducted on target hardware (e.g., Beagle Bone Black Rev. C - http://beagleboard.org/BLACK). Upon completion of the training, you will receive access to a Docker image containing Ubuntu 14.x with all dependencies pre-installed, along with example files, enabling you to engage with the course material in your own lab environment. Please note that this is not an introductory course to Embedded GNU/Linux. Participants should already possess a fundamental understanding of how Embedded GNU/Linux operates, including the ability to configure and build the GNU/Linux kernel and its drivers.

Who should attend?

This course is ideal for those who already use GNU/Linux in their projects and have likely heard of the Yocto Project but have hesitated to explore it in depth or found it challenging to utilize effectively. If you are uncertain about integrating your daily workflow into the YP and generally perceive the YP as overly complicated, wondering why such complexity is necessary when things have traditionally been simpler, this training will help you determine whether the YP is right for you. The workshop is designed for software developers, systems engineers, testers, administrators, and other interested parties with a solid grounding in Embedded GNU/Linux.
