I believe that the "platform_lib" library mode in the Processor Expert KSDK settings (see below) is not working. I have created a project with and without this selected and I see no difference in the files that are copied or linked from the KSDK. Even with this option selected, all of the fsl_*_driver files are still copied into my PE project. Has anyone used this with success?
Note that I am using KDS 3.0 with KSDK 1.2.
