How to write eeprom in s32k116?

shyamalasundar — Thu, 21 Jun 2018 07:00:38 GMT

looking for driver support to write data (in bytes) into eeprom of S32K116 microcontroller.

I got emulation and configuration of eeprom in s32k116.

But need the driver part of writing bytes of data into eeprom.

s32k116 eeprom; writeeeprom flashpartitioning flexnvm‌

Hello,
If you need a driver, you can use the SDK.
The flash_partitioning_s32k116 example uses FLASH_DRV_EEEWrite() function.

I can able to view the written data from 00 to FF in the eeprom memory locations.

And now i need to read what has been written already in those locations.

A sample code to read data from eeprom of s32k116 will be of more useful.

And further i can't view any backup of data into flexNVM.

If it is happening kindly tell how to view and understand that also.

Hi,
The SDK example shows how to verify written data in EEPROM.

So just modify that code to:

uint32_t data = *((uint32_t *) address)‍

The EEE backup is not mapped, it is visible only to the EEPROM state machine.
