Patching Unpatchable Files

In the Yocto world, the .bbappend file is a well-known and documented mechanism for altering recipe files, and an essential part of daily operations. While not common, there are instances where it becomes necessary to modify other file types, such as .inc or .bbclass, which do not offer an equivalent append mechanism. This session will summarize various strategies for effectively handling these file types when patching cannot be avoided.

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

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

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.
