Dragon12 • MC9S12DP256 or MC9S12DG256 • HCS12 family of MCUs • Dragon12P User's Manual • D-Bug12: • Debugger (take around 200KB of flash) • Allows run small program from RAM • Alternatives: • SerialMonitor (SM): Small loader to enable loading a program to MCU’s flash directly via MCU’s serial port 0. • BDM: Generic name for hardware-base debugger to allow real-time debugging and fully control MCU and its flash.

  4. CodeWarrior Development Tools • For HCS12: CW SE 5.1: Special Edition v5.1 • CodeWarrior Special Edition - HCS12(X) - Classic • How to prepare CW to create suitable S record files for D-Bug12: • We simply use Dragon12 Stationaries (e.g. Templates): • CSE3215 CW Stationery.ZIP • For details on how to setup from scratch: • Setup CW Project from Sctrach

  5. Connecting to D-Bug12 • Use HyperTerminal (HT) • Serial Port COM1: BAUD: 9600, 8 N 1 and no flow control. • Reset the board to see D-Bug12 prompt • Type “help” to get details • Type “load” to load your S19 files (e.g. final compiled and linked executable). Use “Send Text File” of HT to send the file • Type “g 2029” to execute your program • CW may change 2029 … look for it in CW mapper files in your project. Look for “Entry” keyword.
