You’ve probably seen abstract hardware interfaces implemented on popular development boards. Many boards provide a standardized connector interface like mikroBUS, Feather, MicroMod, Arduino UNO, etc. A defining characteristic of these interfaces is the ability to plug […]

Let's walk through how to tell Zephyr there is both a "Rev A" and "Rev B" of your hardware. We'll finish up by talking about how Golioth organizes OTA firmware updates for your different board revisions.

Perhaps the most interesting part of this is that it can be done entirely with the configuration code, without needing to dive in to any of the C files. And as […]
