QD4 EEPROM Emulation

I am trying to write some 70 bytes  into the flash of QD4 during run time.

I have 256 bytes of RAM, most of it is allocated. Although can spare a good amount for stack.

What do you think is the chance of achieving this in such kind of setup?


I understand that Flash erase and Write functions have to be copied in RAM and run from there.

Further I am intending to compare this block of data (written as a constant in Flash)  with actual data arriving in RAM.


I need to know the feasibilty for this with 256 bytes on hand.

I really dont have any other choice than QD4,so can't use other devices.

Please provide some comments/pointers/anything as usual.


Thanks and regards
