I found a help screen that says the partitioning of the FlexNVM by the debugger is controlled in the Advanced Options dialog. The help screen shows the dialog and it has a partitioning check box. However, when I bring up the dialog in my CodeWarrior (10.2) there is no check box. I bring up the Advanced Options dialog as follows:
Run -> Debug Configurations
In resulting dialog 'edit' the connection
then click on "Advanced Programming Options"
