Building Embedded Systems with AOSP

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. Of course, embedded Android is not a solution for each issue. Nevertheless, the AOSP provides a sophisticated base platform which is packed with a

  • modern UI stack
  • robust media and camera implementation
  • modern AI runtime
  • well known abstraction between system and app development
  • energy optimization

and lots of other helpful infrastructure.
This makes AOSP an interesting approach for building more complex embedded systems.

A first goal of this talk is to show in which situations choosing AOSP over a plain Linux system really adds value and where not. But where to start and how are the best workflows? The AOSP is a massive and complex code base with a few hundred GB of source code. Navigating the sources, finding the right place to do changes and working with several code repositories at once is a tough task at the beginning. Thus, the second goal of this talk is to share best practices and hints to avoid lots of pitfalls from 8 years of doing embedded Android projects in different setups and sizes.

Organizing My Desk as an Embedded Engineer

Organizing My Desk as an Embedded Engineer

As an embedded dev, my desk is always a mess (and I think the ones of my colleagues, too). Working with real hardware leads straight to a number of boards, additional debuggers, tools, cables and more. And of course, as the most developers, I have a number of work projects and another of private ones. Even worse, I’m working from home for a good share of my time, so both kinds contribute to the mess there. Managing this is a constant effort and fight, but rarely successful.

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.

Google is now increasingly pushing into the automotive sector with Android Automotive. But what exactly is Android Automotive or the Android Automotive Operating System (AAOS)? How does it differ from Android or the AOSP? And what are the advantages over classic operating systems for infotainment?

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.

When setting up a new project from scratch, we focused on proper solutions for

  • a maintainable, well supported and patchable build environment for the embedded systems
  • version control, reproducible builds and continuous integration
  • license management
  • a secure and stable update mechanism on image base and
  • managing releases The talk aims to show how we build a system that matches our requirements using the Yocto Project, KAS, Gitlab CI, and Mender.io. Besides, we will have a short outlook to the application built in Flutter.
