Read/Write S32k's Internal EEPROM

vpsrprathap — Wed, 17 Jun 2020 07:13:57 GMT

Hi Team,

I am working on S32K116 chip with Internal EEPROM. I am able to read/write the data into it.

But i wanted to get the WARNING/ERROR status for the below scenarios from the internal EEPROM to MCU.

As i see in the NVM Manager there is nothing which written to MCU, but taking care of resetting using Debug warning things.

Please help me in how can i get the status from the Internal EEPROM on Read/Write failures.

Regards,

Hi Prathap,

I suggest looking at the document AN11983 Using the S32K1xx EEPROM Functionality

About incorrect data written, since FlexRAM does not support ECC you can consider performing CRC check.

So, the multi-bit data errors in EEPROM backup (E-Flash) memory could be detected.

Also, you can check the discussion below:

I hope it helps.

Best regards,
