ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.

Pharos is a free open-source RTOS for secure, safe and real-time systems with the following characteristics: - Memory and enhanced time partitioning (TSP) - Native support for sporadic, periodic and aperiodic threads - Fixed-priority preemptive scheduler - Execution time protection (threads are prevented from executing for more time than they are configured to) - Small size (full image has ~100 to 300KiB text, ~30KiB data) - Hard real-time determinism - Fast critical sections - Prioritized nested interrupts - inter-partition communication with filters to protect unwanted access - Multicore support (RMP) - Supports ARM9, Cortex-A/R/M and Aarch64, RISC-V64 (64 bits) - The complete TestSuite (see below information) is run successfully for each platform in each release - Tested: more than 170 KLOC of requirement-based tests, executed for each board at each release - Up-to-date User Manual also available See our wiki page for more information.

fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface

This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.

FiwixOS 3 is a Fiwix distribution, an operating system made from a software collection that is based upon the Fiwix kernel. It basically comprises a Fiwix kernel, GNU tools, libraries and additional software. All the included software is free and open-source software made available both as compiled binaries and in source code form, which allows modifications to the original software. FiwixOS 3 uses the Newlib v3.1.0 as its C standard library, and the Ext2 as its primary file...

scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on small uCs with as little amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.

...It is currently being developed for the AVR architecture. Main Objectives of the Avark operating system is to facilitate multitasking. Currently a round robin scheduler is being employed, but soon a priority based preemptive scheduler will be developed. Resource guarding of various CPU peripherals will be implemented using device drivers for the peripherals and semaphores. Do send me feedback at my email id. amol.1991@gmail.com Does it work? Is it insanely useless?

Unix-like operating system for the TI-89 and TI-92+ graphing calculators.

Kmax 8bit microkernel for AVR ATMega MCUs written in assembler (AVRASM & GCC compatible) with a C API. Core features include priority-based preemptive round-robin scheduling, mutexes, fifos and semaphores with a focus on speed and ease of use.

Free and simply RTOS for AVR at assembler. So far, the AVR Studio is used as a development environment. The system supports the preemptive and cooperative multitasking modes, semaphores. Use a small amount of memory for tasks.

SangMyung Univ. Graduate Project Project: MyRTOS Team name:Software Craftsmanship Description: pxa255 based RTOS. Preemptive Multi-threading,Priority-base,Round-Robin Scheduling, Thread, Semaphore,Message Mail Box,Message Queue Management Support.

A small micro operating system kernel written in C (and partly assembly). Planned features are: software based preemptive multitasking/threading, paging, kernel API, IPC, client/server, security system. The code is designed to be clearly understandable.

XMK is a preemptive multitasking kernel for microcontrollers. Its goal is to provide a RTOS small enough (RAM+ROM) to run on 8bit microcontrollers. XMK provides additional/optional features when scaling up to 16bit and 32bit platforms.

The goal of the Christ-OS project is to create a real time micro kernel operating system with a preemptive kernel for embedded systems.

beetleOS is a small and flexible real time OS for embedded systems with preemptive multitasking. It also provides a lightweight device-driver framework. It is basically programmed for the ARM7 processor architecture but it could be ported to other archit
