Power Cycle Dialog

benthie — Thu, 27 Jun 2013 15:20:56 GMT

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

That has fixed my problem, yes. Sorry for not evaluating the answer. I´m sort of a newbie here :smileywink:
