Hi Wang,
1. The KSDK1.x and 2.x are mainly support the basic kinetis products K L series , the KEA belong to
Auto group, not the same line. So there is a specific software for KEA.
2.There is a KEAZ128_KEAZ64 SDK drive using S32DS:
NXP Freedom Development Platform for Ultra Reliable Kinetis EA Series MCUs|NXP

3. As there is a driver for S32DS, so you can use the S32DS , while you can also continue using CW/KDS with PE, the existing function with PE won't disappear, also there is demo code under PE components.
Hope it helps
Have a great day,
TIC
