Yocto Project application developers have traditionally used the toolchain SDK model where installers could be GBs in size and had to be rebuilt, downloaded and re-installed each time anything in the distro changed. The Extensible SDK (eSDK) has addressed this shortcoming by creating installers as small as 35MB with components downloaded on demand. These components can be updated in a granular fashion, rather than re-installed. The eSDK also provides the powerful devtool that allows packages and images to be built, rather than just application executables. This presentation will show how distro developers can create small updatable eSDK installers while ensuring optimal package build times. The presentation will also describe the eSDK lifecycle from the application developer's perspective and show how devtool can be used to create and modify packages.
