USBDM is a debugger hardware interface for a range of Freescale microcontrollers. It is designed to work with Freescale's Codewarrior software under Windows and Linux. More recently basic support for Coldfire with Codesourcery Tool chain has been added (WIN only).

The attached files provide a port of a combined TBDML/OSBDM/TBLCF code to various processors. The primary motivation for doing this was to produce a single BDM that could be used with the following processors.

RS08
HCS08,
HC12,
Coldfire V1-4 microcontrollers
MC56F800xx Digital Signal Controllers.
Kinetis ARM-cortex
Other features have also been added compared to the original TBDML/OSBDM designs.
