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

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 - using Perfetto with Android and Yocto, - adding trace events to your applications, - recording traces and - analyzing system and application traces with the graphical GUI. This will allow you to take full advantage of the Perfetto trace viewer UI for analyzing memory usage, CPU scheduling, latency and more.

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.

Android Automotive OS: A short introduction into Google's AAOS

Android, or the Android Open Source Project (AOSP), is primarily known from the smartphone market. What is less well known, however, is that the AOSP also provides a good basis for embedded systems and ensures a pleasant reading experience on eReaders, for example.

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.

LoRaWAN in theory and practice: A trip through Munich

LoRaWAN (Long Range Wide Area Network) is becoming increasingly popular, thanks in part to public networks such as The Things Network, which allow users to dispense with their own gateways. LoRaWAN also promises potential in terms of range and energy efficiency.

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.

Building Embedded Systems with AOSP

In our community, building embedded systems based on Linux, e.g. with Yocto or buildroot, is standard and well known. Considering Android, respectively the AOSP as a base system feels strange at the beginning as it is a huge ecosystem that implies high system requirements.

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.

Raspberry Pi für die professionelle Produktentwicklung - Eine gute Idee?

Maschinen und Geräte durch Vernetzung und Software aufzuwerten ist ein Kerngedanke des IoT. So werden die resultierenden Projekte häufig aus der Fachdomäne mit dem Wunsch nach schnellen und einfachen Erfolgen gestartet. Die Idee liegt dann nahe den beliebten Raspberry Pi als Basis zu nutzen.
