Zephyr RTOS Bring-Up on the STM32F746G Discovery
Zephyr is a small, open-source real-time operating system built for resource-constrained embedded devices. It supplies the pieces that are easy to underestimate when starting from bare metal: a preemptive kernel, threads and synchronization primitives, interrupt handling, device drivers, logging, networking, and a build system that works consistently across many microcontroller families. The application can focus on its own behavior while Zephyr and the board support package handle the low-level integration.
