AVR ATmega port of freeRTOS A port of freeRTOS which can be flexibly flexibly configured use almost any available Timer on AVR ATmega devices and will operate with almost any classic Arduino device from Arduino, SeeedStudio, Sparkfun, Freetronics or Pololu. Going forward this repository will be updated less often and only with major releases. Please check at Github for the latest commits. https://github.com/feilipu/avrfreertos The Goldilocks Analogue story is told here....

The Femto OS is a very concise portable preemptive operating system for embedded devices with minimal ram and flash, up to say 16K flash, 1K ram. The main target is the AVR architecture, such as the ATtiny861/461/261 series.

AvRtos is a small, preemtive, priority based real time operating system for Atmel AVR and ARM microcontrollers. It was written in C. AvRtos provides message queues and semaphores for task synchronization. It uses a static memory allocation scheme. AvRtos is nearly the smallest RTOS out there. Even pico]OS is much bigger. AvRtos can be compiled using gcc compiler. There is a AvrStudio 4 and Eclipse project file to get the example code working very quickly.

UFFS: Ultra-low-cost Flash File System, designed for NAND flash working in embedded system. UFFS typically consumes less then 200K ram for 1Gb(page 512)/4Gb(page 2K) NAND flash. It supports direct flash interface, works with or without OS.

Flashmon is a Linux kernel module that monitors NAND flash memory access events using Kprobes and Jprobes. Flashmon targets embedded boards shipped with bare flash chips managed with MTD : mainly JFFS2, UBIFS and YAFFS based systems. The monitored events are : flash page read / write requests, and flash block erase operations. Instructions on how to use Flashmon are included in the archive.

The Advanced XIP File System is a Linux kernel filesystem driver that enables files to be executed directly from flash or ROM memory rather than being copied into RAM.

Ivmuk-OS is small RTOS for microcontrollers with low resources. Microchip's PIC16F877A MCU uses about 70 bytes of RAM and 800 bytes Flash. Memory usage depends on number of tasks and messages defined. This should create competition to Salvo OS some day.

Blob is a boot loader for SA11x0 (StrongARM) platforms. Blob is able to boot a Linux kernel stored in flash or RAM and provide that kernel with a ramdisk (again from flash or RAM).

Embedded churn will provide developers the freedom to configure an embedded system for any target architecture from a defined template . The ability to deploy the custom image on a flash based device depending on the application of the embedded linux de
