Hi Peter,
That is strange, I did not get such error.
- Confirm that the linker file (MK64FN1M0xxx12_flash.ld) is actually present in that path.
- Give a check to the linker file path in the project settings:

- Also, looking at your console the error makes me think that the space in "KINETIS Demo" is still causing trouble. I would highly recommend you to place KSDK in the C:\nxp.
Regards!
