Hi,
The 0N57U is a final production version and there no boot rom code. Thus the FOPT bits are not used anymore.
The 0N77P was just a pre-production prototype and it differed significantly from the current production version.

Hi,
Below is the FOPT register description from 0N77P mask-set RM.
There was Boot Source Selection bit on the first S32K144 protopype mask-set.
Use the AN12130 configuration if you have the production version 0N57U.

Hi,
Thank you for your support.
But, I was more confused. my production version is 0N57U, I don't know what's meaning of it. Will it be updated later, or I can keep ordering it for years?
And I also don't know "boot from flash" and "boot from ROM". Maybe "boot from flash" means run my code. what's "boot from ROM"?
