Open IoT & ELC 2017

Software updates are a required feature of any embedded system. They are often added late in the development cycle just before going to production.

By adding the ability to remotely update to the AGL system early on, we avoid last minute hacks and have been able to use OTA to support continuous integration builds. By dog-fooding the update process during development we ensure that the only part of the system that has to work--the updater that lets you repair a broken system--is well tested by the time it is used for real.

In this talk I will describe what we did, how it works, why you might want to reuse it in your system and where the integration points are between our Yocto layer and your BSP.
