Press Release

Jacksonville, FL – September 25, 2006 – CMX Systems, well-known designer of real-time operating systems, TCP/IP stacks, Flash File Systems and USB stacks, announced today the availability of free USB software for Freescale's MCF5222x family of ColdFire microcontrollers. The newly introduced MCF5222x family of controllers enables embedded design engineers to take advantage of cost effective 32-bit processing and realize fast, re-programmable embedded system designs using off-the-shelf microcontrollers.

Chuck Behrmann, president and CEO of CMX, said, “We are very pleased to offer embedded designers free USB embedded software supporting this newly introduced, exciting processor series. We feel that this combination of Freescale processors and CMX software provides developers with an elegant and cost-efficient solution for their designs.”

Notes from Freescale

This is a beta release. Several issues have already been pointed out:

1) If you currently have an M52223EVB then it is an Alpha board. In addition to an extra connector to adapt to the incorrect USB connector on the PWB, and little or no docs, you will need to pull the jumpers from CLK0 and CLK1. Also pull the jumper from the Vbus select. This is for HOST mode which is not released yet.

2) You will have to load the board with code. As shipped these alpha boards are empty or loaded with test code.

3) Read the directions - they are in the root install directory (\MCF5222x_device_HID_beta). There are three HID demos, and in a separate project, a CDC demo.

4) For the HID demos - Windows should automatically recognize these. *** But be aware that Windows will NOT detect a change in USB configs on an active port.*** You must un-plug and re-plug the USB cable so that Windows will re-enumerate.

5) For the third project the executable is in the \MCF5222x_device_HID_beta\hid-led-demo\Debug directory.

6) The CDC class demo is a separate project and again must be compiled and loaded. On plugging in the cable, Windows will prompt for an install. The mcf5222x.inf file needed is in the \MCF5222x_device_HID_beta\src\mcf5222x\cdc-demo directory.
