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 for embedded devices. During this practical course, participants will learn how to utilize Buildroot effectively: - How to select the software components that will be included in the root filesystem. - How to add new packages and modify existing ones. - How to incorporate support for new embedded boards. Throughout the course, participants will create bootable filesystem images. Remote courses are conducted using the QEMU emulator, while in-person sessions may use either QEMU or actual embedded boards chosen by the instructor. Other projects with similar objectives include the Yocto Project and OpenWRT. For detailed comparisons to help determine which solution is best suited for your needs, please refer to these presentations: [Buildroot vs. OpenEmbedded](https://bootlin.com/pub/conferences/2016/elc/belloni-petazzoni-buildroot-oe/belloni-petazzoni-buildroot-oe.pdf) and [Embedded Linux Build Systems](https://elinux.org/images/0/0a/Embedded_Linux_Build_Systems.pdf). These resources are particularly useful for government agencies seeking to standardize their embedded systems development processes.

In this instructor-led, live training in US, participants will learn step-by-step how to build an embedded Linux system from the ground up. From constructing a minimalistic kernel to configuring the bootup and initialization processes, participants will gain the tools, techniques, and mindset necessary to deploy a fully functional embedded Linux system for government applications.

For remote trainings, QEMU will be used to emulate the hardware. Other platforms, including real hardware devices, can be considered on a case-by-case basis to ensure alignment with public sector workflows and governance requirements.

An embedded system is a specialized computer system designed to perform a specific function within a broader mechanical or electrical system, frequently under real-time computing requirements. These systems are integral to various applications and are essential for government operations that demand reliable and timely performance.

Embedded Linux & Yocto is a build framework and development ecosystem utilized to create customized Linux distributions for embedded devices. This instructor-led, live training (available online or onsite) is designed for beginner to intermediate level embedded developers who aim to use Embedded Linux and the Yocto Project to develop, customize, and deploy Linux-based systems on an i.MX6 hardware platform. By the end of this training, participants will be able to: - Understand the architecture of an embedded Linux system on an i.MX6 platform, including the bootloader, kernel, device tree, and root filesystem. - Set up a build environment using the Yocto Project (Poky + BitBake) tailored for the i.MX6 board. - Construct a custom Linux image, install it on the hardware, and execute user-space applications. This training is aligned with best practices for government to ensure efficient and secure development processes in public sector workflows.

Description

This five-day training course combines hands-on exercises with comprehensive instruction to provide a deep understanding of GNU/Linux kernel internals and device driver development. It is designed to bring participants quickly up to speed by covering the essential processes, concepts, and commands needed for writing effective GNU/Linux device drivers.

Description

This four-day training combines theory with hands-on exercises to introduce the Yocto Project. It addresses frequently asked questions such as:

• Is it really necessary to use different versions of the toolchain, libraries, and packages for each GNU/Linux project, and follow a distinct workflow?
• Can you ensure that the development environment is identical for all developers and suppliers, and still produce consistent builds even 10+ years from now?
• Can the Yocto Project help identify the software licenses under which the packages you use are licensed?

Hands-on sessions are conducted on target hardware (e.g., Beagle Bone Black Rev. C - ). After the training, participants will be able to download a Docker image with Ubuntu 14.x and all dependencies pre-installed, along with examples, to work with the course material in their own labs. Please note that this is not an introductory course to Embedded GNU/Linux. Participants should already have knowledge of how Embedded GNU/Linux works and how to configure and build the GNU/Linux kernel and kernel drivers.

Who should attend?

This training is designed for individuals who are currently using GNU/Linux in their projects and may have heard about the Yocto Project but have not had the opportunity to explore it further or encountered difficulties in its use. If you are unsure whether your daily workflow can be accommodated within the Yocto Project and find it complex, this course will help you determine if the Yocto Project is necessary for government projects. The workshop is aimed at software engineers, development engineers, system engineers, testers, administrators, and other professionals with a solid understanding of Embedded GNU/Linux.
