Description

• 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...
  

Features

• 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... :)

Requirements

• 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...

Installation

• Unpack the archive to your harddrive
• When using WindowsNT, unpack the "ntdriver.zip" archive and follow the included installation procedure.
• Thats all!

History

• V1.00
  ** first official release **
• V1.02
  - 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 directory. fixed.
  - 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.
