Add Support for New Boards to Mainline Linux, U-Boot and Yocto

UD2.120 (Chavanne)
Michael Opdenacker
<p>In the course of the past months, Michael has added or expanded support for new ARM and RISC-V boards to the Linux kernel (6.19+), to Yocto BSP layers and hopefully before FOSDEM 2026, to the U-Boot bootloader.</p> <p>This turned out to be much easier than expected, thanks to the availability of device drivers for most hardware blocks, and thanks to the possibility to reuse code (especially Device Tree) for already supported boards.</p> <p>So, if you have hardware sitting idle or working suboptimally because of quick and dirty vendor kernels and BSPs, join this talk and learn how to let the mainline Linux kernel, U-Boot and appropriate Yocto Project layer fully support your board. This should enable other contributors to get involved, and make it much easier for community projects to adopt such hardware too.</p>

<p>When a Python program crashes, a backtrace is printed — often enough to pinpoint and fix the issue. When a C or C++ program crashes on an embedded Linux system, however, nothing appears by default — except perhaps the dreaded “Segmentation fault” message. Unfortunately, there’s no simple --enable-backtrace option to enable human-readable backtraces at build time. Even worse, generating useful backtraces involves many subtle factors, and there’s no comprehensive resource that ...

<p>Rust is rapidly reshaping how we build reliable software — including in areas once dominated by C. But what does it really look like to bring Rust into an existing embedded codebase? This talk shares the hands-on experience of migrating a working ESP32 firmware from C to no_std Rust, highlighting what Rust changes, what it improves, and where the bumps in the road are.</p> <p>Starting from a hobby project — a wireless arcade button used in a multiplayer blind test game ...

<p>Ariel OS is a new RTOS for microcontrollers written fully in Rust. It supports popular hardware architectures (Cortex-M, ESP, RISC-V) and popular boards from vendors such as Espressif, Nordic, Raspberry Pi and ST. Ariel OS is built on top of Embassy and the embedded-hal traits, adding various OS functionalities and a multi-core capable scheduler. Ariel OS further aims to integrate the best of the available embedded Rust ecosystem to provide a seamless, batteries-included experience for ...

<p>What happens when you mix German luxury engineering with a bit of DIY spirit? You get the world’s most over-engineered office chair.</p> <p>This talk dives inside a BMW comfort seat — so when you get home in your 7-series, you can feel right at home in the same seat at your desk. Packed with ECUs, motors, pumps, heaters, ambient lighting and airbags, we’ll explore how it all works, how the seat communicates over CAN, j1850 CRCs, some quirks, and how an ESP32 can take control of ...

<p>Secure-boot projects often end up with a zoo of nearly-identical bootloader images for development, factory, and field use with each variant adding more risk.</p> <p>This showcase illustrates how to avoid this entirely: one bootloader image that adapts securely to each lifecycle stage using fuse-based state transitions, device-bound unlock tokens, and policy-driven access control.</p> <p>With barebox and OP-TEE, we’ll show how these mechanisms enforce secure operation while still allowing ...

<p>Contemporary embedded SoCs increasingly act as a network of specialized CPU cores, some dedicated to user applications, other dedicated to real time tasks, others to security. All those cores still share one set of critical peripherals, which require resource access coordination. This is increasingly implemented by making all cores talk to a dedicated core called SCP, the System Control Processor, using SCMI protocol. The SCP is responsible for coordinating access to critical resources, ...

<p>Secure-boot chains in embedded systems have largely converged on common building blocks like FIT, dm-verity or UKIs.</p> <p>The bootloader is anchored in hardware trust, then verifies an operating system image, and the chain continues, eventually covering the application.</p> <p>But there is a gap when it comes to adding unit-specific bits of information, such as per-device configuration, hardware calibration, or MAC addresses needed early in boot.</p> <p>In this segment, I present the TLV ...
