Hi K6Dwmv,

I would recommand to contact the support line, details can be founded here:
http://www.freescale.com/webapp/sps/site/homepage.jsp?nodeId=054670&tid=FSH

Create a Service Request at: "Submit a service request" you should have a FSL account to access this page though.

Now regarding your request, the closest  supported PQ2 into CW is 8245, if you create a dummy project through the project wizard, you'll see it is using the "Sandpoint_init.cfg" and the "Sandpoint.mem" files. I would recommand to use those first... if it does not do the trick, please submit an SR.

Hope this helps...

Regards
