Hi Yajun,
With the introduction of the Kinetis SDK v2, no new device support has been added to Processor Expert. So you have to use the (now MCUXpresso) SDK for the K66 (First NXP Kinetis SDK Release: SDK V2.0 with Online On-Demand Package Builder | MCU on Eclipse).
About "not use KDS", are you using the Driver Suite? Because you have to use some kind of IDE (KDS, MCUXpresso IDE, IAR or Keil) to build your code, right?
I hope this helps,
Erich
