Hello,
I have encountered problems during trying to enable the Csec feature on S32K144, and to do so, the first step I tried is to partition the flexNVM to 32K/32K and I found out that when the FCCOB1 is set to non-zero while the rest of FCCOB is set to exact same as Figure 5 in AN11983, then the operation is failed with FSTAT->ACCERR set.
For your information,
- This departition command is executed from RAM
- The Interrupt is suspended before executing this command
- Erase all blocks command and Program the secure field (0x40C) have been executed successfully before this command
- When the FCCOB1 is set to zero, the rest code is unchanged, then this command will be successful
Solved! Go to Solution.

@lukaszadrapa thank you, after checking, the order information of MCU I used is S32K144HFVLH and the 'F' indicates "CANFD FlexIO" without security. I guess the higher version MCU of the S32K144 needs to be used to enable the Csec
