Yocto on the Edge - Unusual challenges when building not so embedded systems

Yocto on the Edge - Unusual challenges when building not so embedded systems

Building embedded systems with Yocto on ARM platforms is a common practice, but when the products move further to the edge and become less “embedded,” new challenges arise. In this session, we will explore the requirements and challenges faced when developing Yocto-based systems for edge computing based on Intel.

Advanced System Profiling, Tracing and Trace Analysis with Perfetto in Android and Yocto

Advanced System Profiling, Tracing and Trace Analysis with Perfetto in Android and Yocto

Together with my colleague Stefan Lengfeld.

Tracing is a capable mechanism for deep system analysis and profiling with a minimal overhead. By recording defined system events, in Linux but also Android, tracing can be used to analyze concurrency or latency issues, for example. Android’s systrace tool made it easy to analyze and correlate traces and events due to a graphical UI, in order to help developers identify performance bottlenecks. The successor to this advanced and convenient tool is called Perfetto. It’s available for pure Linux too, and part of Yocto (meta-oe) since Langdale now. In the talk, we’ll have a look into

Embedded World 2024

Embedded World 2024

While I’m a regular visitor of the Embedded World Exhibition, this year was different. I had not only a more business-focused visit with lots of meetings with old and new partners and customers, but I also had the chance to serve rather spontaneously as a speaker, or better “Table Captain,” at the second edition of Embedded World’s women networking event #women4ew. Thus, I want to recap both parts separately and make a reference to what changed in contrast to my experiences outlined in the recently published post on International Women’s Day.

International Women's Day - Why I wear Yocto Shirts on the Embedded World Exhibition

Today, on the occasion of International Women’s Day, I’d like to give you an insight on working in Embedded as a woman: Why I’m searching for my best Yocto shirt and the nerdiest hoodie when I’m visiting the Embedded World exhibition.

USB Updates - Challenges, Approaches and Practical Tips

USB Updates - Challenges, Approaches and Practical Tips

Over-the-air updates have established themselves as the standard for networked devices, but the effort involved in operating the server side is not always commensurate with the benefits. In such cases, the supposedly simple and quick solution of implementing updates via USB is often chosen. But is it really always that uncomplicated? What considerations are necessary to implement USB updates effectively?

Building a Yocto Pipeline with KAS, GitHub Actions and AWS

Building a Yocto Pipeline with KAS, GitHub Actions and AWS

Using KAS makes handling Yocto Projects easy. By shipping its own container with all needed dependencies, building sophisticated CI pipelines becomes pretty easy - in theory, or when using Gitlab. But using GitHub as a code hosting platform with self-managed Action runners on AWS comes with a set of unexpected challenges.
Anna-Lena will talk about her quest through GitHub Actions, the Cloud and how to tame them. The talk aims to point the audience to the obstacles when building CI pipelines for the Yocto Project with KAS, GitHub Actions, and custom action runners on AWS and strategies to handle them.

How a modern Yocto setup could look like

How a modern Yocto setup could look like

In 2015, we built a sophisticated meeting room information system based on Android Things as a student project. As Android Things was deprecated in 2021, we started to use our Yocto Project experience to develop a maintainable, future proof embedded system.
