DEMO9S12XDT512 USB-to-BDM communication

I recently started to work on the development board DEMO9S12XDT512. I followed the Quick Start Guide provided with the board. The first time I connected the board to the PC, everything was working well : the USB, USB PWR OUT, and +5V LED were turned on and the pre-installed program was running.

As asked on the Starter Guide, I installed CodeWarrior Develpment Studio for S12X v5.1, and modified the program. When I clicked on "debug" the True-Time Simulator & Real-Time Debugger window appeared and after a long loading time, the next message appeared : « Communications with the target failed : The target MCU has no clock or wrong BDM clock speed is used or derivative is secured. ». And then the USB and USB PWR LED turn off and never turned back on.

I tried to uninstall and reinstall CodeWarrior but the debugging operation never succeded.

On the Troubleshooting section of the starter guide is requested to install CWS12X P&E USB2.0 Service Pack. But after many research I didn't find anything about it on the Internet.


How can I solve my problem ?
