As AMD officially moves away from PetaLinux, new development within the AMD ecosystem is moving toward the Embedded Developer’s Framework (EDF) and Yocto-based workflows. For engineering teams, this isn’t just the end of a tool but a shift in embedded Linux development practices that could affect future designs. So, what now? How do you pick between EDF vs Yocto? Let’s look at how to choose the right path forward for your team and your product.
What Is PetaLinux?
PetaLinux was the AMD packaged embedded Linux SDK built on top of Yocto. It provided a simplified workflow for building Linux images targeting AMD devices, with preconfigured board support packages, integrated toolchain support, and tight alignment with Vivado and Vitis. It was designed to reduce complexity and accelerate bring-up, especially for teams that did not want to manage Yocto directly. AMD is deprecating PetaLinux in 2026.
Why Engineers Used It
- Rapid bring-up: Prebuilt BSPs and integrated toolchains mean less setup time
- Tight AMD alignment: Works seamlessly with Vivado/Vitis reference designs
- Low learning curve: Engineers could get Linux running on AMD FPGAs without deep Yocto knowledge
- Good for standard designs: When the Linux stack is mostly a support layer, not product-critical
Trade-off: Limited visibility and control over the underlying Linux system. Engineers are constrained to what PetaLinux provides.

What Is Yocto?
Yocto is an open-source build system for creating custom Linux distributions. Unlike PetaLinux, it gives developers full control over the Linux stack: what goes into an image, how it is built, and how it is maintained. Yocto serves as the foundation for many vendor-specific tools, including PetaLinux and EDF. It’s widely used in embedded systems where control, reproducibility, and long lifecycle support are critical.
Why Engineers Should Use It
- Full control: Engineers can define exactly which packages, patches, and layers are included
- Reproducibility and compliance: Ideal for regulated, safety-critical, or long-lifecycle products
- Highly customized systems: When Linux itself is part of the product’s value or differentiation
- Vendor-independent portability: Workflows are portable across platforms and devices
Trade-off: Engineers must manage build infrastructure, layers, and maintenance themselves. Initial bring-up takes longer, and the learning curve is steep.
What Is EDF?
The Embedded Development Framework (EDF) is the new AMD software platform for embedded Linux development. EDF is built on Yocto but provides a structured environment with AMD-supported workflows, prebuilt components, and integration across evaluation, development, and deployment. It is intended to replace PetaLinux for new designs while offering more transparency and flexibility.
Why Engineers Should Use It
- Continuity from PetaLinux: Minimal disruption for teams used to AMD workflows
- Structured, AMD-supported environment: Prebuilt components, board support packages, and workflow guidance remain intact
- Greater transparency: Engineers see Yocto layers, recipes, and configurations, so they can debug, patch, and customize without losing support
- Balanced control vs speed: Engineers get faster bring-up than raw Yocto but more flexibility than PetaLinux
- Future-proofing: Aligns with AMD’s current ecosystem, avoiding reliance on deprecated tools
Best for: Teams migrating from PetaLinux who want continuity plus the ability to tweak, maintain, and evolve the system over time.

What EDF offers:
- Preserves the workflow advantages of PetaLinux
- Prebuilt images and BSPs for rapid bring-up
- Yocto-based transparency into system components
- Strong alignment with AMD-supported ecosystem
- Structured yet flexible path for future designs
How to Choose Between EDF vs Yocto:
Start With How Your Team Actually Works
Before choosing a tool, it helps to step back and look at how your team develops embedded systems. Some teams prioritize fast bring-up and tight alignment with AMD reference flows. Others need deep customization, long lifecycle support, or strict control over every component in the Linux stack. With PetaLinux being deprecated, the decision between EDF and Yocto becomes clearer once you map it to your workflow.
EDF: The Natural Next Step for Most PetaLinux Users
For many teams, EDF will feel familiar in the ways that matter. It keeps the advantages that made PetaLinux effective for bring-up and integration, but it’s built on a more transparent, Yocto-based structure. You still get board support packages (BSP), prebuilt images, and a defined workflow, but you are no longer isolated from the underlying system.
That makes EDF a strong fit for teams that want to stay aligned with the supported AMD ecosystem while gaining more visibility and flexibility over time. If you’re coming from PetaLinux and want continuity without starting from scratch, this is usually the right place to start. EDF is also the natural choice for FPGA developers who want speed and continuity, and have minimal Linux expertise.
Yocto: When Control Becomes the Priority
Some teams will take this opportunity to move directly to Yocto. This typically happens when the Linux distribution itself is part of the product’s value. Long lifecycle programs, highly customized platforms, and systems with strict compliance or reproducibility requirements often fall into this category.
Yocto gives you that control. You define exactly what is built, how it is built, and how it evolves over time. The tradeoff is that you own more of the system. Build infrastructure, layer management, and long-term maintenance become part of your engineering responsibility. For teams that need that level of control, it’s worth it. For teams that don’t, it can slow things down unnecessarily. Yocto is better for teams with strong embedded software skills, Linux expertise, and highly specialized needs.
A Practical Way to Decide Between EDF vs Yocto
In most cases, the decision becomes clearer when you look at two factors. The first is how much customization your system requires. If your Linux stack is relatively standard and your focus is on application development or hardware integration, EDF will usually get you there faster.
The second is how much internal expertise you want to build around the build system itself. If you want full ownership and have the resources to support it, Yocto makes sense. If not, EDF provides a structured path without requiring that depth on day one. There isn’t a single right answer across all programs, but there is usually a right answer for a specific team and product.
Practical considerations to guide the choice between EDF vs Yocto:
- How close your system is to a standard BSP versus a heavily customized distribution
- Whether your Linux stack is part of your product differentiation or just an enabler
- The expected lifecycle of the program and how often updates will be required
- Your team’s familiarity with Yocto concepts like layers, recipes, and build configuration
- How much control you need over package selection, patching, and versioning
- The importance of reproducible builds and long-term maintainability
- How tightly your workflow needs to align with AMD-supported tools and reference designs
- The amount of time available for initial bring-up versus long-term optimization
- Whether you have internal resources to own and maintain the build system over time
- How portable your solution needs to be across platforms or vendors

What This Enables Going Forward
The shift away from PetaLinux aligns AMD more closely with broader embedded Linux practices.
That means:
- Better alignment with upstream Yocto ecosystems
- More portable workflows across platforms
- Greater transparency into how systems are built
- Fewer constraints tied to a single vendor-specific tool
For engineering teams, that’s a positive change. It puts more control in your hands while still offering structured paths like EDF when you need them.
- Use PetaLinux: Only if maintaining legacy projects with minimal changes
- Use EDF: If you want speed and support for new designs while gaining visibility and flexibility
- Use Yocto: If Linux is part of your product’s core value, requires strict control, or long-term maintenance responsibility
Conclusion for EDF vs Yocto
PetaLinux being deprecated doesn’t mean your existing work is lost. EDF provides a structured, AMD-supported path for new designs, while Yocto gives full control when you need it. Teams can use this transition to simplify workflows, improve maintainability, and align with broader embedded Linux practices. The right choice for your team depends on your project needs, not just the tools available.
