- ColdFire CPUs have a special port for debugging: the BDM port.
The long version of BDM is "Background Debug Mode" and it allows the full control of the ColdFire CPU
via a quite simple interface from P&E.
I got the interface because it is shipped with every ColdFire evaluation board.
The hardware comes with an powerful and simple to use DLL-file but without any debug-software.
- If you start to work with the ColdFire, the BDM-interface is the best way to upload programs to the
system memory and to debug it. You have full access to the CPU, its Registers and all connected peripherials.
Now I had more time to work with my ppQBox and I only had a very simple debug software (I wrote it some months ago)
and wanted to have a really good one. Well, this is the result...
- full access to all ColdFire registers (read and write!)
- built-in disassembler for powerful debugging
- singe step mode
- short-run mode (definable run-time [resolution: 1 ms])
- memory-monitor with all access modes (byte, word, long)
- several upload possibilities for code and data
- download features
- powerful memory manipulation features
- memory tester for checking the system memory
- more things I forgot... :)
- Windows 95/98/NT
- pemicro's parallel port BDM debug cable
- of course a ColdFire-CPU board with BDM-Debug connector for connecting the cable...
Sorry for doing a Windows-version... but P&E had this smart DLL-file and I had not the time to develop a Amiga
shared library... surely I will do so later, but as for now the Windows-version should do it... :)
- Unpack the archive to your harddrive
- When using WindowsNT, unpack the "ntdriver.zip" archive and follow the included installation procedure.
- Thats all!

** first official release **
- BDMDebug now works under WindowsNT, too! (only, if using the ntdriver included!)
- Removed a bug with the saved settings. The old version saved the settings into the last used
- The disassembler had a problem with decoding the "NOT Dx" command. fixed.
- The disassembler MemoBox is now a ListBox, the current executed command is now centered and
marked in the mid of the box. Now there is also a PopUpMenu for saving the contents of this box.
