Hi @pratheek_b,

Please refer to AN11983 Using the S32K1xx EEPROM Functionality

https://www.nxp.com/docs/en/application-note/AN11983.pdf

Section 3.4 S32K1xx EEE ECC error handling

The copy-down of the EEPROM data takes place during the reset sequence if enabled:

And by the Set FlexRAM Make FlexRAM available for emulated EEPROM FTFC command.
