This community is only for MATLAB related topics or SW tools related with MATLAB.
So, any issues related with SDK should be addressed here: S32K since this is the community with experts in that matter.
Regarding your first question please contact: Support|NXP @ Support Request. This way your question will be routed to someone that can provide an expert opinion in this matter.
All i can find in that matter is this statement in the SDK Documentation:
Purpose and Scope
The S32 SDK is a embedded oriented development kit. It allows users to
1. Evaluate and explore the features of the S32 processors; experience how they are supported by working "out
of the box" on NXP development boards.
2. Develop embedded solutions; the NXP SDK is thoroughly tested from development to production.
Hope this helps!
