This project contains software for 'personalizing' the NSLU2 network storage device, manufactured by Linksys. None of this material was written or contributed by Linksys. The NSLU2 is run by embedded Linux, and as such, is perfect for 'personalization
ext2/3/4 library for microcontrollers
The main goal of the lwext4 project is to provide ext2/3/4 filesystem for microcontrollers. It may be an interesting alternative for traditional MCU filesystem libraries (mostly based on FAT32). Lwext4 may be used with SD/MMC card, USB flash drive or other block based memory device. However it is not good for flash memory–based storage devices. Code is also available on github: https://github.com/gkostka/lwext4 Feel free to contact me: email@example.com
uSmartx is a non-preemptive, multitasking, priority based kernel for use in embedded designs. Its major features are task and time control over system resources, inter task communication and simple memory management.
pico]OS is a highly configurable and very fast real time operating system (RTOS). It targets a wide range of architectures, from very small 8 bit processors and microcontrollers up to very huge platforms. Ports are available for ARM, AVR, PPC, MSP430, 6502, MYCPU and for developing and testing purpose also for 8086, Win32 and Unix. pico]OS 1.0.4 was released 2012-07-12. This is a maintenance release that includes some bug fixes for the new ports for MSP430 and ARM Cortex-M. You may also visit Ari's website that contains cool stuff related to pico]OS: http://stonepile.fi/tags/picoos/
MinopsOS is a tiny operating system for PC computers.
MinopsOS is a tiny operating system for PC computers. It's small enough to fit inside the boot sector of a floppy disk.
Oberon V4 for Linux and sources for different Oberon V4 implementation
Here you can find both an Oberon V4 system for Linux (x86) as well as a collection of sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server and on the one of the University of Linz where Mössenböck's group did further development after he left ETH and the Group at ETH concentrated on System 3. More Information can be found in the wiki https://sourceforge.net/p/oberon/wiki/Home/ of this Project and on Wikipedia https://en.wikipedia.org/wiki/Oberon_(operating_system). In 2013 they were moved here for easy access and, in case of interest, collaboration on further development. The Oberon mailing list is an established channel for its discussion and followed also by the administrators of this SF project.  ftp://ftp.ethoberon.ethz.ch/Oberon/OberonV4/  ftp://oberon.ssw.uni-linz.ac.at/pub/Oberon/  https://lists.inf.ethz.ch/mailman/listinfo/oberon
Streamline is a pipelined I/O subsystem for both kernel and application processing on Linux, with 40+ filters for pattern matching, stream reassembly, compression, etc. It exports the pipes, sockets, and pcap interfaces and uses shared memory to reduce I

Open-source RTOS and Embedded Systems Toolkit for C++ and C
Mark3 is a sophisticated RTOS and embedded systems toolkit, targeted towards a growing list of MCUs. Beyond providing "just another scheduler", it provides heaps, drivers, a shell, an event-driven GUI framework, and much more! It currently supports a variety of Atmel AVR, MSP430, and the ARM Cortex-M series of microcontrollers, with other platforms to follow. Mark3 was designed from the ground-up using disciplined object-oriented design principles - and unlike the vast majority of free or commercial RTOS' is written in C++, with bindings for C-language compatibility. The carefully designed object model drastically reduces the overall size and complexity of the source code, leading to enhanced code reuse, stability, and modularity. It also makes the source easier to understand - any experienced C/C++ developer should be able to understand the relationship between objects in the system, as well as use and extend them to fit a given application.
Kernel based checkpointing for Linux
Cryopid2 is a development of the excellent Cyropid process freezer for Linux developed initially by Bernard Blackham. Cryopid2 adds a host of functionality to the original package.

Implementation of embedded open source linux system designed (but not limited) to run on Raritan's OPMA card or in an User Mode linux session on any x86 host.
A new kernel I am developing in my spare time. The eventual solution I hope will involve a 32 bit base kernel and 64 bit extensions therefore maximising compatibility with non 64 bit machines. Database oriented. Checkout http://www.love2code.org UPDATE 18-Dec-2011 Updates haven't occurred for some time (April) due to working and studying for my Computer Science degree at the University of Ulster, but it's Christmas! so may be we'll get a little closer to doing some more work. I have been somewhat worried about the number of downloads taking place, so I must point out, in no way can this system be used (yet), it's an exploratory project and while it does have some graphics and other bits, only the code at the moment is useful for anyone. Feel free to look at the code (or run iso in VirtualBox) and feel free to join in.
The Trion Object Oriented Operating system is an OS that is designed to meet the needs for the 21st century, with a kernel written in C++ and modelled in UML, and lots of features. The project is run by a team of OSDev.org community members.
