COFILOS
A Development Framework for Coldfire
Contains a framework for Coldfire MCUs like 52254.
The framework supports a Command Line Interface (CLI) that may work from Serial port, USB or ENET.
The framework uses Processor Expert and IDE requirement is MCU Eclipse 10.4 from Freescale.
Includes the FunkOS Realtime Operating System by Funkenstein Software Consulting, available at http://funkos.sourceforge.net
Mainly it is a support package for the development board Perseus, but I have ported also the RTOS to MCF52233DEMO...
