Hi,
Kinetis KSDK 2.0 uses a different approach for structuring files than the previous versions, please try creating a project manually by following the legacy device tutorial: http://visualgdb.com/tutorials/arm/legacy/
You would normally need to import at least the following files:
- The startup file (.S)
- The linker script (.ld)
- The drivers files (e.g. fsl_gpio.c)
If this does note help, please let us know the details on the errors you encounter so that we could help you further.
