Hi, all,
The KDS tools focuses on Kinetis processor including KE/KEA/KV/KW... and K families, the S32 design studio tools focuses on auto processor including the KEA and Power PC families. Because the KEA family belongs to both Kinetis family and auto family, so both KDS and S32 tools support KEA family.
I suggest you use KDS tools to develop application for KEA family, the KDS tools exists for a long time, we have a lot of example based on KDS tools, furthermore, the KDS support SDK, the SDK is a driver for Kinstis family.
This is website of KEA family:
ARM Cortex-M0+|Kinetis KEA 32-bit Automotive MCUs|NXP
Hope it can help you.
