MPC5606B : Accessing D-Flash area for NVM data

In our project for storing of NVM data we are having 2 options one is EEPROM (external to MPC5606B) and also D-Flash which is within MPC5606B ( Limited to 64KB).

I would like to use the 64KB D-Flash area to store,read and write application specific NVM data. I need suggestion or sample code to know how could i access this area for my application.


Basically i would like to store,read and flash data into this section separately when compared to C-Flash area.

Also during compilation itself i would like to tell/address to compiler that these NVM data resides in D-Flash area.


Please suggest me different design options so that i can choose the best needed for my application.


Below is my environment details :


Board : MPC5606B

Compiler : GreenHills

Configuration Tool for Firmware : RappiD

IDE : Eclipse

P.S : When we exceed 64kb then we will use EEPROM chip for NVM store,read and write.
