Online Training: The Yocto Project

The Yocto Project - An Overview

The Yocto-Project (YP) represents an Open Source project which provides templates, tools and modes to generate embedded products independent of Linux based systems and their hardware architecture. Even experienced GNU/Linux-users might be unfamiliar with how to accommodate their workflow to YP and whether they need it at all. This seminar will give answers and show the most important elements which define the Yocto Project.

The seminar’s aim is to impart the essentials necessary for using YP, based on existing knowledge in GNU and Linux.

In order to have a solid base for this seminar, we recommend taking at least the seminar Embedded Linux in Theory and Practice. Further knowledge in GNU and/or Linux would be of advantage.

You can also book this seminar as an in-house seminar! Just write us a short non-binding e-mail with the desired date and location as well as the number of participants: training@eclipseina.com

Methods and Training Materials

Lecture and practical examples with host (laptops with Ubuntu 14.04.x LTS) and target system (e.g. Beagle Bone Black Rev.C - http://beagleboard.org/BLACK). The devices will be provided during the training. You receive a reference- and workbook, one Beagle Bone Black Rev.C plus one standard FTDI 3.3 V to USB cable.

After the training you will get access to a download link with a prepared Docker image and examples.
