Flex NVM on S32K

My target is S32K, I'm using EVB144 and design studio.

I'm using flash_partioning example as a reference for implementation of EEPROM in my project.

Using openSDA for flashing and debugging. I can partition Flex NVM and write to EEPROM on the same power cycle and when I power off and on again it works as well, That is the partition is preserved. However to test this I tried to remove  FLASH_DRV_EEEWrite(&flashSSDConfig, address, size, sourceBuffer);

statement which writes to EEPROM and see if the data is preserved in EEPROM.

Commenting that statement out and download of the code breaks the whole thing loose.

I get SIM->FCFG1.DEPART =0XFFFF and a running reset. I don't know if this is a TOOL issue (MASS ERASE PRE DOWNLOAD)

or something that I'm doing or not doing. I am not doing anything outside the project example .I can't find a range for addresses to download on this TOOL for flash programming.


I just don't know what's causing this.

Any Ideas?

really need help with this.
