What is FLIRT? FLIRT is for developers who want a small, easy to use and simple to port operating system for a truly tiny multithreaded system on an 8-bit MCU, without sacrificing the ability to multithread and share CPU time effectively. It is presently written for the MC9S08 core by Freescale (hopefully others later).
You will need Freescale's development environment Codewarrior to compile FLIRT. It has a code size limitation and most of the features are only valid during the 60 day evaluation. You can find it here:

If you want more power out of an MC9S08 than FLIRT can give, I highly recommend Helium:
