Embedded Linux using Yocto Part 4

Learn the below concepts by enrolling in this course

•  What is clean build

• What is incremental build

• Example of clean and incremental build

• Shared State Cache (sstate-cache)

• Build performance with and without sstate-cache

• Tasks in Yocto

•  What’s the benefit of per-task over per-recipe approach

• How does shared state cache works (checksum/signatures and setscene)

• Commands: bitbake-dumpsig, bitbake-diffsigs

•  SSTATE_DIR variable

•  Bitbake Clean tasks: clean, cleanall, cleansstate

• What happens when you say bitbake target

• PROVIDES list and what’s the benefit of PROVIDES list

• Bitbake namespaces: recipe names (build time targets) and package names (run time targets)

• RPROVIDES , virtual targets and PREFERRED_PROVIDER

• How to select a recipe when multiple recipe of same name and different version exists

• Yocto Linux Kernel Development (kernel source, configuration, patches)

• Linux Kernel Recipes in Yocto (PREFERRED_PROVIDER/PREFERRED_VERSION)

• Creating a new kernel recipe in Yocto

• Kernel customizations (changing kernel configuration – savedefconfig)

• Kernel recipe with source code on git repository

• Patching the Linux Kernel

• Yocto Linux Kernel Recipes

• Modifying an existing kernel recipe (configuration fragments, patch, diffconfig, LINUX_VERSION_EXTENSION)

• Using an in-tree defconfig file (KBUILD_DEFCONFIG_KMACHINE)

• Difference between general kernel and yocto kernel repository

• What is Package group

• Difference between package group recipes and normal recipes

• Writing a package group recipe (RDEPENDS, RRECOMMENDS, BAD_RECOMMENDATIONS, NO_RECCOMENDS, PACKAGE_EXCLUDE)

• Recipes for out of tree modules (module.bbclass)

• Automatically load modules on boot
