Problems Entering Debug Mode with MC9S12DT256 and CodeWarrior v5.7.0

Hi there, I am working on a Freescale HC12 chip connected to an Axiom CSM12D Board, but cannot successfully enter debug mode. If I hook up the board, communication can be established with the axIDE terminal. The following message is displayed: Axiom Manufacturing CSM12D Education Module MC9S12DT256 MCU This message is displayed everytime the RESET button is pressed that same message is displayed. The problem arises when I try to put a sample program on the chip using CodeWarrior. The code I am trying to use was provided by Freescale, and all it should do is light up an LED when one of the onboard switches is depressed. When I try to connect with CodeWarrior using the HCS12 Serial Monitor, the following error messages are produced: Cannot connect to hardware. I did make the project first. Then entered debug mode, which is where the error presented itself. Does anyone know if there are common problems with this board or this version of CodeWarrior? Thanks for your help, batgirl

You best bet is to try Axiom tech support first.
If that doesn't help fell free to ask again.
Are you a student?

When you say your entering debug mode are you referring to CodeWarrior debug or are you actually doing the procedure on the HCS12 to put it into Debug Mode. The process being something like hold SW1(or SW2), press RESET, wait a few seconds then release SW1 (or SW2)
