Automotive Grade Linux Ships First Open Source SoDeV Reference Platform for Software-Defined Vehicles, Adds Five New Members
AGL released the initial SoDeV reference platform in its 'Ultimate Unagi' code base on May 14, 2026, bundling Xen, Zephyr, and Linux containers to decouple vehicle software from hardware.

- Correction:
- The article attributes the sentence about "Ultimate Unagi" being supported "for the next two years, with updates released approximately three weeks after each Scarthgap release" to Automotive Testing Technology International. That outlet does not carry the statement; the verbatim wording appears in the Linux Foundation, Automotive Grade Linux, and PR Newswire announcements, which are also cited in the article. The fact is accurate; only the inline citation pointed to the wrong outlet.
Overview
Automotive Grade Linux (AGL), a collaborative open source project hosted by the Linux Foundation, has released the first version of its SoDeV reference platform for software-defined vehicles and welcomed five new members. The initial release shipped on May 14, 2026, inside the latest AGL Unified Code Base, codenamed “Ultimate Unagi,” according to the Linux Foundation.
The platform packages several Linux Foundation projects into a single pre-integrated stack aimed at letting automakers build vehicle software before the target hardware is finalized.
What We Know
The SoDeV reference platform combines the AGL Unified Code Base with Linux containers, the Xen hypervisor, VirtIO, and the Zephyr RTOS, along with other Linux Foundation projects, in a single pre-integrated package, as reported by Automotive Testing Technology International. According to the Linux Foundation, the underlying code base is built on the Yocto Project’s Scarthgap LTS release 5.0.16.
The stated goal is to break the dependency between writing software and waiting on silicon. “SoDeV enables automakers and suppliers to decouple software development from hardware availability, accelerating SDV time-to-market,” the Linux Foundation said. The platform targets consolidation of electronic control units, hardware abstraction through virtualization, and cloud integration for software-defined vehicles, according to Automotive Testing Technology International.
The initial release runs on Renesas Sparrow Hawk reference boards, cloud-based processor environments, and virtual machines, according to the Linux Foundation. The “Ultimate Unagi” code base will be supported for the next two years, with updates released approximately three weeks after each Scarthgap release by the Yocto Project, as reported by Automotive Testing Technology International.
Alongside the release, AGL named five new members: EMQ, Lineo Solutions, MediaTek, VA Linux Systems Japan, and Very Good Ventures, according to the Automotive Grade Linux project. Per the same announcement, EMQ contributes data backbone and connectivity work, Lineo Solutions brings embedded Linux expertise, MediaTek adds automotive silicon and software, VA Linux Systems Japan provides Linux kernel engineering, and Very Good Ventures focuses on Flutter-based in-vehicle UI development.
“We’re excited to welcome these new members to the AGL community, each of which brings distinct and valuable expertise to the table,” said Dan Cauchy, executive director of Automotive Grade Linux, as quoted by Automotive Testing Technology International. In the PR Newswire announcement, Cauchy added that “the ecosystem around our SoDeV reference platform continues to grow, reflecting the breadth of innovation that open source collaboration makes possible.”
The broader SoDeV effort draws contributions from Panasonic Automotive Systems, Honda, Toyota, Mazda, AISIN, and Renesas, according to the Linux Foundation.
What We Don’t Know
The announcements describe the initial release as running on Renesas Sparrow Hawk boards, virtual machines, and cloud environments, but do not detail a timeline for broader production automotive system-on-chip support beyond the Sparrow Hawk reference target. The materials also do not quantify adoption, such as how many vehicle programs or suppliers have begun building on the reference platform.
Analysis
SoDeV reflects a wider industry pattern in which carmakers, long dependent on bespoke per-model software stacks, are converging on shared open source foundations to cut development time. By bundling virtualization (Xen, VirtIO), a real-time operating system (Zephyr), and container tooling into one Yocto-based image, AGL is positioning the reference platform as a starting point that suppliers can extend rather than rebuild. The addition of members spanning connectivity (EMQ), silicon (MediaTek), and UI frameworks (Very Good Ventures’ Flutter work) signals that the project is trying to cover the full vertical stack of a software-defined vehicle rather than the operating system layer alone.
