Programming Romeo2 Monitor into the MC68HC908AP64 MCU
If the Romeo2 monitor program has already been programmed into the MC68HC908AP64 Demo Board,
the user can begin to use the monitor (see section 'Using The Software). Otherwise, the user must follow
the programming procedure described below.

select Project->Debug from menu bar. This launches the debugger, which communicates with the
MC68HC908AP64 Demo Board and attempts to burn the Romeo2 monitor program into FLASH
memory on the MCU. The “Attempting to contact target and pass security…” window should
appear. Please make sure the following options are configured correctly.

You must have a copy of the CodeWarrior development tool for HC(S)08
installed. A copy of CodeWarrior is supplied with the MC68HC908AP64
Demo Board. Please follow the instructions supplied with the demo board
to install CodeWarrior.
This project does not contain any source code. If you wish to read or modify
the Romeo2 monitor source code, you should unzip
fileRomeo2AP64MonSource.zip (contained in file AN2818SW.zip). To
modify this code, you require a full license for CodeWarrior, which can be
purchased from www.metrowerks.com, or your local Freescale or
MetroWerks representative.
