4-day Zephyr RTOS training
with Andreas Klinger

symbol-Online-Meetings.svg

Implement real-time development professionally with Zephyr

The Zephyr RTOS Zephyr is a modern, scalable, real-time operating system for resource-constrained embedded systems. In this 4-day in-person training course, you will gain practical experience with Zephyr's architecture, development environment, and core mechanisms.

All exercises are performed on the phyBOARD Lyra KIT, equipped with the phyCORE AM62x.

Required previous knowledge:

  • Solid programming skills in ANSI-C
  • Basic Linux knowledge (for the development computer)

To the speaker

Andreas Klinger, IT Klinger
is a freelance trainer and developer. Since graduating with a degree in electrical engineering in 1998, he has worked in the field of low-level software development, specializing in kernel drivers, embedded Linux, and real-time applications. As a specialist in Linux and Zephyr, he focuses on the internal structure of the kernel, system mechanisms, and, above all, their use in embedded systems. He has contributed to the Linux kernel, the Zephyr kernel, and other open-source projects. He was an ESE Congress speaker from 2008 to 2025 and received the Speaker Award in 2011, 2014, and 2018. He has published several articles in the ESE Report and Elektronik-Praxis. 
 

Price

The price per person is €2.600 net, including phyBOARD Lyra, power supply, and SD card.

Minimum number of 4 people

The Zephyr RTOS training is an in-person event.
Food and drinks will be provided on all days of the event.

Description:

  • Providing practical knowledge in key Zephyr topics such as multithreading, memory management, interrupts, device tree and hardware connectivity
  • Building a solid understanding of efficient and robust real-time system architectures
  • Gradual application of learned knowledge to concrete development tasks
  • Development of a complete example project during the training process
  • Integration of typical embedded features such as logging, shell, network connectivity, GPIO and I2C
  • Holistic project setup – from configuration to functional implementation

  • Exercises
    • All exercises are performed on a phyBoard-LYRA using freely available software.
      Open-source tools were used with a Linux host system.
    • Practical exercises are provided for all topics so that what has been learned can be tried out immediately.
      can be explored in greater depth.
    • At the end of the seminar, the participant will have a sample project (logging sensor data) with frequently used
      The required features (logging, shell, network, GPIO, I2C) were created.
