Practical guidance on building a purpose-built Linux for industrial hardware — getting to the field faster and keeping devices updated reliably over their whole life.
Bit-for-bit reproducible Yocto builds: where non-determinism sneaks in (timestamps, paths, floating SRCREVs, host contamination), how hash equivalence and shared sstate fix it, and the CI check most teams skip.
A practical guide to Yocto layer structure: BSP vs distro vs application layers, bbappend discipline, why layer priority isn't importance, pinning, and the five-step cleanup backlog for inherited platforms.
A/B partitioning explained practically: how dual root filesystems make field updates atomic and self-healing, how rollback logic actually works, and how SWUpdate, RAUC, and Mender compare.
Secure boot on industrial hardware, explained practically: the chain of trust, key management, what it protects against, what breaks, and what it won't save you from.
Managing one edge device is easy; managing a thousand needs a cloud backbone. Secure onboarding (fleet provisioning, X.509), fleet monitoring, and OTA updates on AWS IoT — and how to build it in from day one.
Updating fielded devices without bricking them is where products live or die. How Yocto plus A/B root filesystems, atomic rollback, and signed updates (RAUC, Mender, SWUpdate) make field updates safe.
A custom OS sounds slower, but a well-built Yocto image gets industrial products to the field faster — validated BSP, a lean image, an app SDK, reproducible CI builds, and fleet-scale provisioning.
Yocto isn't a Linux distro — it's how you build one. A practical intro to BitBake, layers, and BSPs, and why a custom Yocto Linux beats Debian for fielded industrial products.
