S12ZVCA - bdm connection lost [SOLVED]

Hi all,

I'm using an S12ZVCA with Codewarrior 10.7 on a Windows 7 PC and PE Micro USB Multilink Universal BDM interface.

 

I'm not able to debug my software as the connection is lost very often.

When the problem happens all the memory read from the micro is read as 0xEE and I have to reset the microcontroller using the reset command .

 

It looks like a connection lost problem or an unexpected reset of the microcontroller.

The things happens in the following way:

 - Start a debug session

 - Start the microcontoller

 - Pause the microcontroller after a while.

Sometime, after a few seconds, the microcontroller restart by itself and the connection is lost.

 

Anyone experienced similar problems? Any idea what could be the problem?

 

Thank You, everyone
