BDMDebug

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...

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... :)

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.
