Hello ,
1) There isn't official FRDM-KEA128 demo support KDS,
so there is two methods if you want to develop on KDS.
- There is demo on CW, you can create a bareboard project on kds, then copy the application
files into it , build until to there is no error. You can download the CW example at here :
NXP Freedom Development Platform for Ultra Reliable Kinetis EA Series MCUs|NXP
(FRDM-KEA Quick start package)
- You can also create a project on kds with Processor Expert, then there is demo when add related component :

For example add "Gpio" componnet :


2) There also some project developed on KDS:
I wonder how to get CAN to work with KDS's Processor Expert?
3)Please refer to the uick Start Guide to start your board , I attached it for you .
4) The KDS is mainly for kenitis chips ,the S32DS mainly for develop the Auto produces .
Have a great day,
TIC
