Build Systems — Yocto & Buildroot
Automate the entire toolchain, kernel, rootfs, and package build pipeline. Learn Buildroot for simplicity and Yocto/OpenEmbedded for production-grade flexibility.
Buildroot Basics
Configure Buildroot, understand the directory layout, select packages, and build a complete toolchain + kernel + rootfs image.
Buildroot Packages & Board Config
Write custom .mk package files, board defconfigs, overlay directories, and post-build scripts for production targets.
BitBake & Recipes
BitBake syntax, recipe structure (SRC_URI, do_compile, do_install), bbappend files, and the fetch/unpack/patch workflow.
Yocto Layers
Layer architecture, bblayers.conf, creating a BSP layer, meta-* conventions, and integrating upstream community layers.
Custom Distro
Define your own distribution policy, IMAGE_FEATURES, package groups, and IMAGE_INSTALL for a locked-down production image.
SDK Generation
Generate standard and extensible SDKs (eSDK), distribute to app developers, and use devtool for fast iteration.
CI / Automated Builds
Integrate Yocto/Buildroot into CI pipelines with shared sstate-cache, reproducible builds, and artifact management.
