Working with the Linux Kernel in the Yocto Project
summary
Covers how to add a custom kernel into a Yocto build, showing the concrete workflows: add a recipe that pulls from git or a tarball, use config fragments or a defconfig, capture changes as git commits or patches, and recompile with BitBake using commands like bitbake -c menuconfig and -C to force rebuild. Demonstrates the devtool workspace workflow that checks out sources, runs kernel configme and builds, warns that work directories get wiped so changes must be captured into VCS or layer patches.
