EEPROM write and read in s32k while device is secure

[Saranraj]

I tried writing and reading to the EEPROM, and it works when the device is unsecure. However, after enabling device security through the FSEC bit and flashing the hex file, the EEPROM stops working.

Hi @Saranraj,

The Flash Configuration Field can also set protection for the Emulated EEPROM.

Do you have a communication interface that can be used to send the content of the 0x400-0x40F memory out while the MCU is secure?
