Bootloaders play a critical role in securing embedded systems, especially when implementing verified boot.
But while much attention goes into the cryptographic boot chain and run-time security, other parts of the bootloader are often overlooked — leaving a key component of the system exposed.
This talk outlines practical steps to harden a bootloader against different real-world threats.
Topics include identifying security-critical functionality, avoiding common pitfalls, slimming down the TCB and what kinds of hard- or software misconfiguration can silently undermine your defenses.
Along the way, we’ll use barebox as a practical example to show complementary approaches — like applying fuzzing to core logic, adding runtime hardening, and securely handling unlock scenarios — as well as how these could have mitigated a number of recently reported vulnerabilities.
Attendees will learn how to reduce risk during early system startup and improve the overall security posture of their embedded systems.

Although Android is pretty common as an embedded operating system, there are surprisingly few opportunities for us developers to come together. This BoF is such an opportunity. If you are working with Android in embedded, Automotive, TVs, custom ROMs or even if you just find this interesting, please come along. Bring with you your experiences, tips, tricks and grumbles about developing Android devices. As a starter, here are some of the topics that have come up in previous years:

In this session, I’m going to give an overview of the open-source ecosystem. I will start very broad, showcasing a selection of projects per category (simulators, middleware, autopilots, libraries and some selected open-source robots). For example, for simulators I’d show Gazebo, Webots, MuJoCo, pyrobosim, ir-sim. For the middleware, I would showcase ROS, YARP, DORA, Copper, and so on.
Then, I would like to focus on one or two hardware projects that are fully or partially open-source, and dive deep into their architecture, and perhaps try to show some simulated demo. The candidates for the deep dive that I'm considering for this presentation are:
