LinuxCon + CloudOpen + ELC-E Europe 2014

Nowadays updating an embedded system is a mandatory feature. Not only security fixes, but also non-critical fixes and new features are regularly available after the initial release of a product. In many cases this means an update must be done in field. My presentation will show advantages and disadvantages of different update procedures (using a bootloader, rescue system, etc.), taking into account the reliability requirement typical for the embedded field. The second part of the presentation will cover the OSS Project "swupdate", that I started some months ago within DENX. It provides a ready-to-use environment for updates, local and remote. Instructions on how the project integrates with ELDK/Yocto will conclude the presentation.
