First read this:
http://forums.freescale.com/freescale/board/message?board.id=CWCOMM&message.id=3819While all CW based tools are using the same ide, the build tools setup matters.
Basically in order to add a file to a project (to a build target), its file type has to be defined in the file mappings dialog in the project settings.
For 8/16 bit (HC08/HC12) there is a "match it all" entry at the end, so any files can be added to a project.
But for other cores (and for the HC08/HC12 if the default file mappings have been changed accordingly),
a mapping for every type of file to be added has to be defined.
