Hi Tymoteusz,
After create a Kinetis SDK1.x project with Processor Expert in my KDS3.2, I can find many KSDK1.3.0 Components like below. You can use them.

Does “Processor Expert components” mean below Kinetis Components(for example _LDD)? If you want use KSDK 1.3.0 with Processor Expert. You can not use below Components.

The Kinetis SDK2.0 for K26 has released, we recommend you download it(SDK_2.0_MK26FN2M0xxx18) from Kinetis SDK Builder (REV 2 & 1.3). Unlike KSDK v1, v2 does not have Processor Expert support available.

You can find the documents in (...SDK_2.0_MK26FN2M0xxx18\docs) folder.

Best Regards,
Robin
