ICON - Eclipseina Embedded Academy Seminar - Embedded Linux - Yocto Project - Pinguin - GNU - C

The Yocto Project - A Summary

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 don’t know how to accommodated their work flow to YP and whether
they need it. This seminar will give answers and shows the most important elements which define the Yocto

The seminar’s aim is the imparting of the required essentials on base of existing knowledge in GNU
and Linux.

As fundamental you should at least took the seminar Embedded Linux in theory and experienced.
Also an advantage would be knowledge in GNU and/or Linux.

This training is also available in German: Das Yocto Projekt - ein Überblick

Target Group

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.


  • Basic familiarity with using a GNU/Linux system (e.g. Ubuntu) as an end user in user space
  • Basic familiarity with a command line shell
  • Basic knowledge of user/kernel space programming with GNU/Linux
  • Intermediate C programming knowledge

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 -
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 an already prepared Docker image
and examples.
