./
flash.dld      - Diab Data linker file for use with Flash programmer
upuser.dld     - Diab Data linker file for use with upuser command
ram.dld        - Diab Data linker file that places code in RAM
objects.txt    - List of all object files used by makefile.bat
makefile.bat   - Batch file for compiling and linking this project
makefile       - Makefile for compiling and linking this project

./obj
This directory is created by the makefiles and contains all the object,
map and executable outputs from the compilation and linking processes.


What does this code do?

The code provided here is configured to initialize the M5407C3 evaluation 
board. 

How do I get the code into Flash?

After making the project using the make of your choice (Makefile or 
Makefile.bat), you will have two .elf and two .s19 files in the obj 
directory.  The 5407initFL.* files are linked to be used with the Flash
programmer of your choice.  The 5407initUP.* files are linked to be
downloaded via a dBUG download command (dl or dn) and programmed into
Flash via the dBUG 'upuser' command.

What do I do after I get the program into Flash?

Once the code is in Flash, simply move the Flash address range
selection jumper to point to the upper address range.  Next, open up a 
terminal program and connect a serial cable to the DB-9 connector on your 
board labelled "Terminal".  Hit the Reset button and you should see the 
following message:

Hard Reset
MCF5407 Initialization Complete!


How do I set up my environment?

1) Extract the initialization template to a working directory.
2) Make sure the makefile (makefile or makefile.bat) points to your
   local compiler.
3) Add your test routines to main.c
