Hello kui,
Regarding your questions please see my comments below.
<1>how to partition the FlexNVM to EEPROM? call this following API? FLASH_DRV_DEFlashPartition
Yes. But keep in mind that before calling this function you need to initialize the driver, this is done with the function FLASH_DRV_Init.
<2>if have partitioned, I want to delete partition information ,how to do?
For this, you can use the function FLASH_DRV_EraseSector.
<3>if have partitioned , I want to partition again, also call the API FLASH_DRV_DEFlashPartition ?
Yes, you can call that function again.
<4>EEPROM has write protect, is there weite protect??
Could you please clarify this question?
As additional information, the SDK for the S32K144 includes an example named "flash_partitioning". This example will help you to understand how the flash partitioning works.
Have a great day,
Victor
