Your Yocto Build Shouldn’t Take
Half a Working Day to Run.

Embedded teams spend hours waiting for builds that should be running unattended in the cloud. We automate Yocto and Buildroot pipelines for firmware teams who need the same reliability from their build process that they build into their products — without adapting a cloud software pipeline and hoping it fits.

Standard DevOps pipelines weren’t designed for this.

Cloud software CI/CD assumes fast builds, consistent environments, and deployments to servers. Yocto is different. Builds take hours, depend on specific toolchain configurations, and need to produce images for multiple hardware targets from the same codebase. None of that fits a standard pipeline template.

Most embedded teams work around it by keeping the process manual — one person, one machine, one long build. It works until it doesn’t. A senior engineer leaves. A build environment drifts. A new product line gets added and the process collapses under its own weight. Automation is the fix, but it has to be built by people who understand firmware development, not applied from a generic DevOps template.

Builds take hours and someone has to watch them. An engineer starts a Yocto build, checks periodically, and finds it failed two hours in with no clear reason.
One person knows how the build works. The environment lives on their machine. When they’re unavailable, nobody else can produce a clean release.
Multiple device lines, each managed separately. Different BSPs, different layer configurations, no shared pipeline — and every new product adds more complexity.
OTA updates are manual or not working yet. Getting firmware to devices in the field involves error-prone steps with no reliable rollback if something goes wrong.

From the Yocto build automation engagement

8x Faster builds. Was 4 to 6 hours per release. Now 45 minutes, unattended.
Zero Manual steps to trigger a build. Every push starts the pipeline automatically.
On-demand Releases — previously fixed monthly cadence. Now ships when the code is ready.
Near zero Release error rate. Previously high and time-consuming to trace and fix.

Six areas, built for firmware teams

01 Yocto and Buildroot Build Automation Manual Yocto builds replaced with automated pipelines using GitHub Actions, Jenkins, or GitLab CI. Builds run unattended in the cloud on every relevant commit and produce versioned, traceable artifacts your team can match to a specific codebase state.
02 CI/CD for Embedded Systems Automated testing, artifact management, and release workflows designed for embedded environments. Not a cloud software pipeline adapted for firmware — a pipeline built around your BSP, your device targets, and your specific release requirements.
03 Cloud Integration for Builds Build pipelines connected to AWS, Azure, or GCP for on-demand compute and versioned artifact storage. Long builds stop tying up local machines. Every output is stored, versioned, and accessible to the whole team without a shared server.
04 Containerised Build Environments Docker-based build containers so the environment is identical across developer machines, CI runners, and release builds. New engineers can run a clean build on their first day without a setup document and three hours of troubleshooting.
05 OTA Update Automation Over-the-air firmware delivery integrated into the release pipeline. Version control across device lines, staged rollouts, and automated rollback if an update causes problems in the field. Getting firmware to devices stops being a manual, error-prone coordination task.
06 Security, Licence Compliance, and Image Validation Dependency scanning, licence compliance checks, and image validation embedded into every build. Security and compliance issues surface during the build, not after a product ships. Particularly relevant for teams working in automotive, industrial, medical, or defence sectors where specific regulatory requirements apply to firmware images.

Yocto Build Automation for a Global Audio Manufacturer

A leading audio device manufacturer came to us with a build process consuming four to six hours per release, run entirely by hand. No version control, no build visibility, no way to track what had changed between images. Their product portfolio was growing and the process wasn’t going to scale. We rebuilt it from the ground up. Repositories moved to GitHub. Yocto pipelines rebuilt with GitHub Actions and cloud compute. Structured logging and versioned artifact storage added throughout. Every build now starts automatically on every relevant push and runs without anyone watching it.

8x Faster. 4 to 6 hours became 45 minutes.
Zero Manual steps per build
On-demand vs fixed monthly cadence before
Near zero Release error rate

What the client said

Stonetusker transformed our Yocto build process from hours to minutes, and gave our team full visibility into releases. The automation saved us time, cost, and rework across projects.

How we approach an embedded automation project

We map your build process exactly as it is today

Before proposing anything, we need to understand your Yocto layer structure, where builds currently run, how releases are triggered, how artifacts are stored, and where things go wrong. We also talk to the people who run the builds — not just the engineers who commissioned them. We sign an NDA before this starts. Your BSP, your layer architecture, and your product configuration stay completely confidential.

We design the pipeline around your device targets and toolchain

The pipeline is designed for your specific build targets, BSP requirements, and hardware configurations. If you have multiple product lines sharing layers, we design for all of them from the start rather than adding them later as exceptions. The plan is reviewed with your engineers before we write a line of pipeline code.

We build it alongside your team, not around them

CI/CD workflows, cloud build containers, artifact storage, OTA delivery, and security scanning are all implemented with your engineers involved at each stage. We explain decisions as we make them. By handover, your team can maintain and extend the pipeline without us. There’s nothing in the system only we know about.

We stay available through the first live release cycle

Your team runs the new pipeline through a real release while we’re available to fix anything that surfaces and answer questions in context. Runbooks covering common failure modes are delivered before we step back. Post-engagement support is available without a retainer, but most teams don’t end up needing it.

Embedded DevOps Pilot

See automated Yocto builds working on your actual setup before committing to the full engagement.

A 2 to 3 week paid pilot on your real Yocto environment — not a proof of concept on a sample project. You see a working automated pipeline before you decide whether to continue.

Build environment assessment We review your Yocto layer structure, current build environment, and release process. We map the bottlenecks and agree on the pilot scope before any implementation starts.
Automated pipeline for your actual build target A working CI/CD pipeline for at least one of your device targets, running unattended in the cloud, producing a versioned artifact with build logging. Done within the pilot window.
Documentation of what was built and why Pipeline architecture, configuration decisions, and how to extend the pipeline to additional device targets — documented during the pilot, not added at the end as an afterthought.
Concrete scope for the full engagement At the end of the pilot, you have a working pipeline, documentation, and a specific proposal for extending automation to all device lines, OTA delivery, security scanning, and anything else the assessment identified.

Pilot guarantee

If the pilot doesn’t produce a working automated build on your actual Yocto setup, you don’t pay for the full engagement.

The pilot delivers a real automated build — running against your actual layer configuration, on your real device target. If it doesn’t, you don’t pay for the next phase. That’s written into the agreement before work starts, not stated as a verbal assurance.

Questions specific to Yocto and firmware automation

Yocto builds take hours. How does CI/CD even work for something that slow?

CI/CD for embedded isn’t about making each build faster — it’s about making the process reliable and invisible. The build still takes time, but it runs unattended in the cloud while the team works on something else. It starts automatically on every relevant commit, logs failures clearly so engineers know exactly what broke and where, and produces a versioned artifact when it succeeds. Nobody has to start it, watch it, or rescue it. On the audio manufacturer engagement, the result was 4 to 6 hours of attended manual work becoming 45 minutes of unattended automation.

We have four different device lines with different BSPs and layer configurations. Can one pipeline handle all of them?

Yes, and this is one of the most common setups we work with. Multi-target Yocto builds are handled by designing each device target as a separate pipeline job sharing a common layer and sstate cache. Build times drop significantly once shared sstate cache is working correctly across targets — it’s often the single biggest improvement. We design for all your device lines from the start, not just the first one, and the pilot covers at least one full target build on your actual configuration.

We need to test on actual hardware, not just in a simulator. Does automated testing still apply?

Yes, if you have physical test boards available. The pipeline can trigger tests on connected hardware as part of the build process, with results and logs reported back to the CI system. If you don’t have hardware test infrastructure in place yet, we scope that as part of the assessment and recommend what makes sense for your product and team size. We’re straightforward about what automated testing can and can’t replace in an embedded context — hardware validation is real work that automation assists, it doesn’t remove it entirely.
