Embedded Linux Conference & OpenIoT Summit North America 2018

A common pain point in the Yocto Project/OpenEmbedded world is that a large amount of work is done on a fork of a particular Yocto Project release. The new development is based on a point in time in the past, meanwhile all of upstream is changing constantly. In a way, your base metadata was obsolete the moment you started. Instead, we chose to run continuous integration builds where the upstream metadata is auto synchronized daily and tests--both emulated and on real hardware—give us confidence that any breakage due to upstream changes or other internal git repositories is caught quickly and fixed. Real hardware testing is crucial in our case, because we are testing the PREEMPT_RT Linux kernel. We will discuss how the overall system architecture and what the individual moving pieces are. We will also cover some lessons learned and areas where the community could drive improvement.
