Hi,
which architecture are you targeting? S32K or MPC57xx?
Anyway, I'd recommend you to start with S32DS example project shipped with S32DS:
.
There are also official SDK documents including Quick Start Guide:
"<S32DS_ARM_v2.0>\S32DS\S32SDK_S32K14x_EAR_0.8.6\doc\"
and some Workshop slides that you might find useful:
Hands-On Workshop: S32 SDK for S32K
Hope it helps.
