Hello,
there is FreeMaster component in Processor Expert, but it is not currently supported for Kinetis family and as far as I know that
currently there is no plan to support it in near future.
However there could be possilbe to convert existing CW free-master project to PE project, but you would need to resolve issues with prm (lcf) file, start-up code and interrupts.
For now if you´d like, you can check the attached solution for HCS12 family, we are going to prepare such project for Kinetis family but it may take some time.
best regards
