Hello everybody,

 

I´m working with a MC9S08QB4 at the moment and my problem is, like the topic already said, the "Power Cycle Dialog". CodeWarrior (10.2) is telling me that the MCU is not responding. I´ve done some research about that problem and usually the first idea is to check the BDM-6Pin-Tool-Connector. I did that and have the following question:

 

Pin1 is connected to BKGD (PTA4) and VSS at the same time?

 

Because if I am not totally wrong, that is what the ReferenceManual (Rev.1, page 25) tells me.

 

Thanks and regards,

Ben

Hello Ben,

The diagram that you refer to is faulty.  Pin 1 of the header is meant to connect to the BKGD/MS pin alone.  Pin 2 connects to ground.

Mac
