About Sample Source: RTOS-From-Scratch
RTOS-From-Scratch is an open-source real-time operating system built from the ground up, designed as an educational project for embedded systems enthusiasts. It focuses on ARM Cortex-M4 architecture (specifically the TI Tiva C TM4C123GH6PM microcontroller) and includes core components such as a kernel, drivers, file system, and data structures. The project uses CMake for build configuration and OpenOCD for debugging. It is currently in pre-alpha state, making it suitable for learning and experimentation rather than production use.
