Dual Core using the same peripherals

[nampt]

"I am using the MIMXRT1170 and building a dual-core project with MCUXpresso Config and IAR Workbench.

I'm wondering how to create the project. Should I configure, generate all peripherals in the master core (CM7) or on separate cores? And what should I do if both cores are using the same peripherals?"

MIMXRT1170-EVK

thank you for your answer.
You mean I can configure on separate cores without the same peripherals?
I need to share 1024 bytes data from CM4 to CM7. Should I use MU, SEMA4 or Free-RTOS Message Buffers for this application for best performance? 
If using Free-RTOS how can I config receive data via IRS RTOS?
