As embedded systems take on more demanding Edge AI, machine vision, robotics, and industrial automation workloads, developers need greater control over the software running on their hardware. At the same time, growing cybersecurity and software supply chain requirements are increasing the need for reproducible builds, software traceability, and long-term system maintenance.
These trends are bringing renewed attention to the Yocto Project, especially as platforms such as NVIDIA Jetson expand Yocto support for building customized Edge AI software environments.
What is Yocto Project?
The Yocto Project is an open-source framework for building customized Linux-based systems for embedded devices. Unlike a traditional Linux distribution, Yocto does not provide a prebuilt operating system. Instead, it provides the tools and build environment developers use to create a Linux image tailored to specific hardware and application requirements.
The Yocto Project follows a regular release cycle, including Long Term Support releases. Yocto Project 6.0 “Wrynose” is the current LTS release and includes Linux 6.18 LTS.
This approach gives developers greater control over what is included in the operating system, from drivers and libraries to applications and system services. As a result, Yocto is widely used for embedded, industrial, IoT, and edge computing systems that require a purpose-built software environment rather than a general-purpose operating system.
Yocto Project vs. a General-Purpose Linux Distribution
| Yocto Project | General-Purpose Linux Distribution | |
| Approach | Build a customized Linux system | Install a prebuilt Linux system |
| Software | Select the components the device requires | Includes a broader package set |
| Hardware | Configure support for specific hardware | Designed to support a wide range of hardware |
| Best Fit | Embedded, industrial, IoT, edge systems | Desktop, server, and general computing |
How Does the Yocto Project Work?
The Yocto Project uses the OpenEmbedded build system to define the hardware, software, and configuration required for a device. BitBake then processes these instructions and builds the resulting Linux image.
- BSP and Machine Configuration: Defines the target hardware, including board-specific settings, kernel configuration, and drivers.
- Layers: Organize hardware support, software, and product-specific customizations.
- Recipes: Define how software components are fetched, configured, compiled, and packaged.
- OpenEmbedded-Core (OE-Core): Provides the core metadata, recipes, and classes used as the foundation of the build system.
- BitBake: Processes the metadata, resolves dependencies, and executes the build tasks.
- Poky: The Yocto Project’s reference distribution and build configuration, commonly used as a starting point for development.
What Are the Benefits of the Yocto Project?
The Yocto Project gives developers greater control over how an embedded Linux system is built and maintained. Five key benefits include:
Customization
Developers can choose the software packages, services, libraries, and features required for a specific application.
Smaller Software Footprint
Unnecessary components can be removed, helping reduce storage and memory usage.
Reproducible Builds
Yocto uses defined recipes and configurations so teams can recreate consistent software images across development and production.
Hardware-Specific Support
BSPs and machine configurations allow Linux images to be tailored for specific processors, boards, drivers, and peripherals.
Security and Software Traceability
Yocto provides tools for vulnerability checking and software tracking, including CVE analysis and SPDX Software Bills of Materials, or SBOMs, that help developers identify and manage the software components included in an image.
What Is Driving Yocto Adoption?
1. Edge AI Optimization Requires a Purpose-Built Software Stack
Edge AI systems often combine GPU or NPU acceleration, cameras, sensors, drivers, AI frameworks, and application software on a single platform. A machine vision system, for example, may prioritize camera drivers, GPU acceleration, inference libraries, networking, and the inspection application.
Yocto helps developers tailor the software environment around these specific workloads, supporting controlled software footprints, hardware-specific integration, and repeatable deployments. This is becoming increasingly relevant in the NVIDIA Jetson ecosystem, with JetPack 7.2 adding Yocto support for supported Jetson Orin and Thor platforms.
The advantage is not that Yocto inherently makes AI inference faster, but that it allows the software stack around the workload to be optimized for the target hardware and application.
2. Cybersecurity Regulations Are Increasing Software Traceability Requirements
Cybersecurity has become a bigger priority for embedded and connected devices, increasing the need for vulnerability management, software traceability, and long-term security maintenance.
The latest LTS release, Yocto Project 6.0 “Wrynose,” is supported through April 2030 and strengthens these capabilities with improved SBOM and CVE tracking and more secure defaults. Yocto 6.0 also uses SBOM-based CVE analysis, allowing developers to identify known vulnerabilities during builds and periodically analyze previously built images.
Yocto can generate SPDX-formatted Software Bills of Materials, or SBOMs. SPDX is an industry-standard format for exchanging software component information, giving manufacturers a machine-readable inventory of the software included in a build.
EU Cyber Resilience Act and Yocto Project
These capabilities are increasingly relevant under the EU Cyber Resilience Act, or CRA, which introduces cybersecurity and vulnerability-management requirements for many products with digital elements placed on the EU market.
Yocto does not make a product CRA compliant by itself, but its long-term support, vulnerability tracking, SBOM generation, and reproducible build capabilities can help manufacturers support their compliance efforts.
Main Industries That Adopt the Yocto Project
Yocto is especially valuable in industries where devices need custom hardware support, controlled software environments, long product lifecycles, and reliable updates.
- Industrial Automation and Edge AI: Machine vision, robotics, and inspection systems often require specialized drivers, accelerators, sensors, and I/O. Yocto helps developers build a software stack around the exact hardware and workload.
- Automotive and Transportation: Vehicles and transportation systems need consistent, maintainable software across long deployment cycles. Yocto supports reproducible builds and platform-specific customization.
- Medical Devices: Medical equipment benefits from controlled and traceable software configurations, especially when hardware and software must remain stable over long product lifecycles.
- Telecom and Networking: Routers, gateways, and network appliances often require compact, purpose-built Linux environments with specific networking features and security controls.
- IoT and Smart Devices: Resource-constrained connected devices benefit from smaller software footprints, hardware-specific support, and tighter control over deployed software.
Bringing Yocto to NVIDIA Jetson Edge AI Computers
With JetPack 7.2, NVIDIA introduced official Yocto support for Jetson, including validated Yocto recipes for Jetson Orin and Jetson Thor platforms through the OE4T ecosystem. This gives Jetson developers another option for building customized Linux environments while retaining access to NVIDIA’s accelerated computing stack.
For custom industrial Jetson systems, hardware-specific BSP support is still required to enable the carrier board, I/O, drivers, and platform configuration.
Premio is preparing the JetPack 7.2 BSP for the JCO Series, with availability targeted for the end of September 2026. This will help our customers build customized Yocto-based Edge AI systems on Premio’s rugged NVIDIA Jetson platforms.
Building Purpose-Built Edge Systems with Yocto
The Yocto Project gives embedded developers greater control over how Linux is built, optimized, and maintained for specific hardware and applications. As Edge AI and cybersecurity requirements continue to grow, this flexibility is becoming increasingly valuable for industrial systems. With Yocto support expanding across NVIDIA Jetson platforms, Premio is extending this capability to its JCO Series to give customers more flexibility in building purpose-built Edge AI deployments.
