Hello.

I'm studying flash memory with s32k144 EV Board.

sorry for not having enough basic knowledge...

First i want you to see these which is from s32k_rm

what is the "0 memory block"??????

and plus this.

what is the 'non-main memory array'??

I drew this memory map as I understood so far.

I guess this memory map is for 'main memory array'..

Please help me!!!

Thanks.

Yes, the IFRs are separate from the main memory map.

It can be programed, erased and read as described in the RM rev.12.1:

Program Once Filed can be programmed only once - it cannot be erased.

It can be read using the Read Once FTFC command.

This Data flash IFR can be programmed using the Program Partition FTFC command and erased using the Erase All Blocks Command.

Also, the FlexNVM Partition Code is loaded to Flash Configuration Register 1 (FCFG1[DEPART]) out of system reset.

Regards,

Daniel
