Hello,
Which device are you working with? Did you install the device-specific Development Package? Did you use the S32DS Extensions and Updates menu to install the SDK? If you installed the standalone version of the SDK, then it will not work with S32DS. You must install the SDK through the S32DS Extensions and Updates menu for it to work with S32DS. Also, you must install the device-specific Development Package (also available through the S32DS Extensions and Updates tool) before you install the SDK.
You can locate the S32DS Extensions and Updates menu by Help -> S32DS Extensions and Updates from the pulldown menu.
Best Regards,
Mike
