Using Yocto to Build an IoT OS Targetting a Crossover SoC - Ryan Fairfax, Microsoft

Описание: Using Yocto to Build an IoT OS Targetting a Crossover SoC - Ryan Fairfax, Microsoft

Crossover SoCs that contain multiple heterogeneous CPUs like the MT3620, STM32MP1, i.MX7 are changing what it means to build software for an IoT device. A single build no longer targets one CPU architecture, one bootloader, or in some cases even one kernel.For the last three years Ryan and the Azure Sphere team have been building a crossover OS using open source build tools. In this talk Ryan will discuss how they extended Yocto to build a multi-architecture OS, the impact to the daily development process, and lessons he's learned as their build systems evolved.
