Automotive Grade Linux (AGL) is a Linux Foundation collaborative project in which automakers, suppliers and technology companies develop reusable open-source software for vehicles. Its Unified Code Base (UCB) is the Linux distribution and automotive software foundation, not a consumer head unit and not a promise that any retail car can be converted to run AGL.
What is Automotive Grade Linux?
AGL provides a shared development platform for automotive software, including infotainment, connected-car services and other vehicle systems. The project says a common code base can reduce duplicated work, shorten development cycles and leave companies more resources for product-specific innovation. Those are AGL’s stated benefits; the published material does not independently quantify realized savings or adoption.
AGL is organized as an open collaboration under the Linux Foundation. Its software, documentation and specifications are intended for engineering projects, suppliers and research—not as a retail operating-system download for car owners. Learn more from the AGL project overview.
What is the AGL Unified Code Base (UCB)?
The UCB is a Linux distribution built jointly by automakers and suppliers for in-vehicle infotainment (IVI), connected-car experiences and related automotive applications. AGL describes it as a potential 70–80% starting point for a production project. That percentage is the project’s stated target, not an independent measurement: a real vehicle still needs OEM or supplier customization, hardware integration, validation, security work and any required functional-safety process.

UCB releases are built for particular targets and configurations. At the time covered by the cited UCB page, UCB 16.0, “Prickly Pike,” was listed as the latest release. Release names and support change, so check the current UCB page and release notes before selecting a version.
What does AGL include?
The UCB page lists these platform capabilities. The exact implementation depends on the release, image and hardware configuration.
- Application framework for automotive software
- ConnMan network management
- Vehicle-bus messaging with built-in security
- Audio routing and mixing
- Multiple-display support
- IP networking, including Wi-Fi and LTE
- A Linux Security Module
- A Yocto-based Linux distribution
- Device profiles for telematics and instrument clusters
- Speech-recognition APIs
AGL’s wider roadmap spans infotainment, instrument clusters, telematics, heads-up displays, advanced driver-assistance systems, functional safety and autonomous driving. The overview describes several of these areas as in development or planned, so a broad project scope should not be read as saying every capability ships in every UCB image. See the published architecture overview.

- 70 Inputs/Outputs originating at the FPGA are available at Stackable Headers organized around the edge of the board. The user can configure these I/O's using the FPGA project code.
- The DPL contains two oscillators, 66MHz and 100MHz. The 66MHz oscillator is used to provide clocking for the EPT ActiveHost USB communications core. The 100MHz oscillator can be used by the user clocked up using one of the onboard Clock-DLL modules.
How is AGL software organized?
The documented architecture separates concerns so teams can replace or extend one layer without rewriting the whole platform:
- Applications and HMI: vehicle-facing applications and user-interface logic.
- Application framework: common interfaces and lifecycle services used by applications.
- Shared user-space services: connectivity, audio, vehicle communication and other reusable services.
- Operating-system layer: the Linux kernel, device drivers and utilities that connect software to hardware.
AGL also lists specialist work in app framework and security, navigation, speech, UI and graphics, connectivity, continuous integration and testing, instrument clusters, telematics, vehicle-to-cloud systems and virtualization. Projects using AGL decide which components and integrations fit their vehicle program.
What is AGL SoDeV?
SoDeV means Software Development Vehicle. In a May 13, 2026 announcement, AGL said an initial SoDeV reference platform was available through the “Ultimate Unagi” UCB release. It combines UCB with Linux containers, VirtIO, the Xen hypervisor, Zephyr RTOS and other Linux Foundation projects.

The purpose is to let developers work on software-defined-vehicle functions before final vehicle hardware is available, while keeping software components separated across virtualized environments. The announcement named Renesas Sparrow Hawk reference boards, cloud-based processor environments and virtual machines as initial environments. It described broader automotive-SoC support as planned through 2026; that dated plan is not confirmation that every target has shipped. Read the announcement at AGL’s SoDeV release notice.
How do you get started with AGL?
AGL’s documentation provides quick-start instructions for prebuilt images, image-building guides for supported targets and an application-development workflow. The safest route is to select a release first, then use only the emulator or hardware listed for that release.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- Read the current documentation: start at the AGL documentation and open the release-specific quick-start and support information.
- Choose a goal and target: use QEMU for an emulated environment, or choose a physical board explicitly supported by the selected UCB release.
- Install or build the image: follow that release’s prebuilt-image or Yocto build instructions for the target; commands and prerequisites vary by release and board.
- Boot and verify the platform: confirm the image starts in QEMU or on the supported board before adding applications or hardware integrations.
- Develop an application: continue with the release’s application-development guide and use the documented framework and APIs.
Raspberry Pi boards appear among AGL’s example hardware targets, but “Raspberry Pi support” is not a blanket claim for every model or release. Check the support matrix before buying a board. QEMU is often the lowest-friction learning path because it does not require a compatible physical head unit or development board.

AGL specification versus an implementation
The AGL specification defines platform architecture and a core software platform from which applications can be built. Application requirements are generally created by the projects that use AGL. The historical v1.0 highlights include a Linux-based IVI reference platform, service requirements such as Wi-Fi and Bluetooth, native and HTML5 application frameworks and APIs for vehicle-bus connectivity.
That specification is not a current release guide, a complete vehicle design or evidence that an application has been certified. Match the specification, UCB release, hardware support and your program’s safety and validation requirements separately.
Is AGL an operating system for my car?
AGL is an automotive software platform and development ecosystem. UCB supplies a Linux-based foundation that an automaker or supplier can integrate into a vehicle program. It is not a consumer product that you install through a car’s infotainment menu, and compatibility with one vehicle cannot be inferred from the fact that the vehicle uses Linux or has an aftermarket screen.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesProduction deployment requires the vehicle maker’s hardware, security model, middleware, user experience, diagnostics, update process and validation. AGL’s published material contains no independent statistic establishing a universal number of deployed vehicles, reliability level or economic saving.
What AGL does—and does not—promise
| Question | What the published material supports | What it does not establish |
|---|---|---|
| How much code can be reused? | AGL states a 70–80% starting-point goal for a production project. | A measured result for every vehicle, or zero remaining engineering work. |
| What features are available? | UCB pages list networking, audio, displays, security, vehicle-bus services and other capabilities. | That every feature is enabled, complete or configured identically in every release. |
| What vehicles can run it? | Reference boards and QEMU are supported paths documented by release. | That a generic consumer head unit or retail car can be converted to AGL. |
| What does SoDeV provide? | A reference platform combining UCB, containers, virtualization and related projects. | Universal support for every automotive SoC or production-vehicle certification. |
Why automakers describe AGL as a foundation
AGL’s homepage publishes executive endorsements, which should be read as company statements rather than independent test results. Toyota executive vice president Keiji Yamamoto said AGL’s flexibility helped Toyota roll out infotainment across its vehicle lineup and focus resources on new features. Mercedes-Benz Vans’ Thomas Wurdig said a standardized open operating system was being used as a foundation for onboard applications such as robotic delivery, data analytics and automation. These quotations show how the companies characterize AGL’s role; they do not prove that every named capability is deployed across all of their vehicles.
