Embedded Linux Build Systems

Note

TL;DR - Hub aggregating all Yocto Project and Buildroot documentation — covering build system setup, custom layer/distro creation, security integration (secure boot, Mend SCA), and CI/CD pipeline integration for production embedded Linux images.

Yocto Project

The Yocto Project is our primary build system for production-grade embedded Linux distributions.

Step-by-step guides:

• Implementing Secureboot with Yocto Wrynose and GRUB — UEFI Secureboot, TPM/LUKS, SELinux, A/B updates with Mender. See articles/yocto/implementing-secureboot-with-yocto-wrynose-and-grub.

Yocto in CI/CD:

• Optimizing Yocto Builds with Jenkins and Resource Throttling — kas-container, SSTATE caching, multi-configuration. See articles/jenkins/jenkins-yocto-kas-pipeline.

• Building Secure Yocto Images with Mend SCA Integration — vulnerability scanning during build. See articles/jenkins/jenkins-mend-pipeline.

Security integration:

• meta-mend — Mend SCA vulnerability analysis integrated into BitBake. See opensource/products/meta-mend.

Buildroot

Buildroot is used for lightweight, single-purpose embedded Linux images.

Guides:

• Flutter on Buildroot — running Flutter apps on Buildroot-built systems. See opensource/thirdparty/buildroot/flutter-buildroot.

• CuteKeyboard in Buildroot — Qt virtual keyboard integration. See opensource/products/cutekeyboard.

• Buildroot Shared State Cache (sstate-cache) — Yocto-style shared state caching for faster incremental builds. See articles/buildroot/buildroot-sstate-cache.
