Hi Saitej,
Please take a look at this example: Example: S32K144 EEEPROM usage
https://community.nxp.com/t5/S32-Design-Studio-Knowledge-Base/Example-S32K144-EEEPROM-usage/ta-p/110...
The PE Micro plugin only allows partitioning the MCU during programming.
Regarding FlexRAM, if used as EEPROM, it can be written only once EEERDY = 1, and I don't think there is an option to do that with OpenSDA.
Please contact PE Micro support for more information.
Thank you,
BR, Daniel
