The Zephyr RTOS has a startup and initialization flow that provides for initialization of C runtime, platform, SOC, and managed bring-up of drivers and system services, allowing developers to initialize custom platforms and hardware for their applications. This presentation will provide a high-level outline of this initialization flow to equip the developer with a deeper understanding of the Zephyr RTOS and how it starts-up and initializes the system, followed by a deeper look into this flow to highlight the hooks provided that allow custom platform/hardware specific initialization. Initialization run levels will also be discussed with examples. Specific SOC architecture differences will be highlighted with a deep dive into 32-bit ARM architecture.
