Hi Lex,
.wsd file is not need to import KDS project.
- goto main menu - FIle - Import - General - Existing Projects into Workspace
- select directory and the project from kds subfolder
Alternatively, you can also clone the project and create standalone project in KDS workspace using
- main menu - File - New - Kinetis SDK 2.x Project
- select SDK path
- select Boards - {board} - Examples - {example}
For this action you need latest version of New Project wizard from KDS update site. This feature also requires some metadata in SDK package, so might not be available for all SDK packages yet.
Regards
Marek
