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

Buildroot is an open-source project that provides 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 these capabilities:

• Selecting the software packages to include in the root filesystem.
• Adding new packages and modifying existing ones.
• Adding support for new embedded hardware boards.

Participants will produce bootable filesystem images during the course. Remote sessions utilize the QEMU emulator, while in-person classes may use either QEMU or actual embedded boards selected by the instructor.

Other projects with similar objectives include the Yocto project and OpenWRT. Please review these presentations to help determine which solution best fits your specific requirements.

Course Objectives

This course aims to provide a comprehensive understanding of embedded GNU/Linux essentials, explaining how its various components integrate to form a cohesive system. It details the necessary ingredients for constructing an embedded GNU/Linux environment, including sourcing, configuring, building, and installing these elements. Participants will also learn where to find support and gain clarity on software licensing. Through hands-on exercises, the course equips learners with the practical skills needed to independently develop embedded GNU/Linux systems upon successful completion.

Description

Over the course of five days, this training blends interactive exercises with instructional guidance to demonstrate embedded GNU/Linux concepts. It is structured to accelerate your proficiency. The course covers the underlying philosophy, core concepts, and essential commands required for effective GNU/Linux utilization, delivered through a mix of theoretical instruction and practical, job-oriented training.

Rather than starting from scratch, learn from an experienced trainer and depart with a functional understanding of GNU/Linux and the capability to apply it effectively in your embedded development projects.

Who Should Attend?

This course is ideal for managers, project leads, software, hardware, development, and systems engineers, testers, administrators, technicians, and any other professionals interested in the technology. It is designed for those who wish to rapidly grasp how Embedded GNU/Linux operates. It is suitable if you currently use GNU/Linux or have the flexibility to evaluate its appropriateness for your needs. It is also relevant if you have previously attempted to use Embedded GNU/Linux but are uncertain about best practices, or if you currently rely on a different operating system and wish to determine if GNU/Linux offers better performance or cost-effectiveness.

Delivery Options

All training materials are provided in English. However, instructors can deliver the presentation in either English or German, available globally.

• Instructor-led, on-site sessions
• Instructor-led, online sessions
• Instructor-led, hybrid on-site/online sessions

This two-day course features approximately 60% hands-on labs focused on Embedded Linux kernel internals, architecture, and development. Participants will explore techniques for writing and integrating various types of device drivers.

Who should attend?

Engineers interested in Linux kernel development for embedded systems and platforms.

In this instructor-led live training conducted at South Korea, participants will learn how to build an embedded Linux system from the ground up, step by step. From developing a minimal kernel to configuring boot and initialization processes, attendees will acquire the tools, techniques, and strategic mindset required to deploy a complete embedded Linux system.

For remote training sessions, QEMU is employed to emulate the hardware. Other platforms, including actual hardware devices, can be evaluated on a case-by-case basis.

An embedded system is a specialized computer system designed to perform a specific function within a larger mechanical or electrical system, typically subject to real-time computing constraints.

Description

This five-day training program integrates hands-on exercises with expert instruction to illustrate the core concepts of GNU/Linux kernel internals and device driver development. The curriculum is designed to accelerate your learning curve, covering the essential processes, concepts, and commands required to create GNU/Linux device drivers through a blend of theoretical knowledge and practical application.

Instead of starting from scratch, learn from an experienced trainer and gain the practical knowledge and skills needed to effectively apply these techniques in your own embedded development projects.

Who should attend?

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

The LEDE Project (Linux Embedded Development Environment) is a Linux operating system rooted in OpenWrt, serving as a full alternative to vendor-provided firmware for numerous wireless routers and non-network devices.

Through this instructor-led live training, participants will gain the knowledge to configure a LEDE-based wireless router.

Audience

• Network administrators and technicians

Course Format

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

This instructor-led, live training in South Korea (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 South Korea, 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 blends theoretical knowledge with practical exercises to introduce the Yocto Project.
It addresses frequently asked questions such as:

• Is it truly necessary to utilize different versions of toolchains, libraries, and packages for every GNU/Linux project, alongside managing distinct workflows?
• Can you guarantee that the development environment remains identical for all developers and suppliers, allowing you to reproduce identical builds over a decade from now?
• Can the YP assist in identifying the software licenses under which the packages you utilize are distributed?

Hands-on sessions are conducted on target hardware (e.g., Beagle Bone Black Rev. C - http://beagleboard.org/BLACK). Following the training, you will be able to download a Docker image containing Ubuntu 14.x with all dependencies pre-installed, along with examples, to enable you to work with the course material in your own lab environments. Please note that this is not an introductory course for Embedded GNU/Linux. Participants should already understand how Embedded GNU/Linux operates and know how to configure and build the GNU/Linux kernel and its drivers.

Who should attend?

This course is for individuals who already use GNU/Linux in their projects and have likely heard of the Yocto Project but hesitated to explore it further or found it difficult to use. It is suitable for those who are unsure whether and how their daily workflows can integrate with the YP and who generally find the YP complex. It addresses the question: Why adopt this complexity when previous methods were (supposedly) simpler? After completing the training, you will be equipped to determine if the YP meets your needs. The workshop targets software developers, system engineers, testers, administrators, and other professionals with a solid understanding of Embedded GNU/Linux.
