Open Source Summit North America 2026 and Embedded Linux Conference brought together the open source community in Minneapolis from May 18–20, 2026. As part of the Zephyr track, Wai-Hong Tam and Jason Yuan from Google presented “Beyond Static Devicetrees: Implementing Runtime Hardware Dynamism in Zephyr.” The session explained how the ChromeOS Embedded Controller team supports many hardware variations with a single Zephyr firmware binary.
