I’ve been studying Real-time operating systems (RTOS) and it’s fascinating. While they’re incredibly basic, they offer a stepping stone into larger more complex systems with file system, multi core, etc. RTOSes emphasize on “real-time” or predictability while general operating systems, they focus on throughput. I recommend looking at FreeRTOS source code or building one from scratch.
