Do you find yourself twiddling your thumbs while waiting for dozens of devices to upgrade over Bluetooth? Or do you think twice before pressing the “Firmware Rollout” button due to the anticipated LTE data bill? Introducing Constrained Patch (CPatch), a binary patching algorithm designed specifically for Firmware Over-the-Air (FOTA) upgrades of constrained devices running Zephyr.
In this session I will step through the design and implementation of the algorithm, including: * Prerequisites for a diff based solution * Constraints the algorithm works within * Embedded patching implementation * Python patch generation * Comparisons against existing algorithms * Live demo!
