Hello Benoit,
Yes, the Processor Expert can't be used at the same time with KSDKv2.x.
I recommend you use the new new NXP Touch Software for the latest software products designed .
It based on the software development kit (SDK) for Kinetis® MCUs .
You can download and find the describe at here :

Hope it helps
Have a great day,
Alice Yang
