[ECOS] FAT32 over NAND

This will be raw NAND flash. 

There are two ways we want to access file system written on NAND flash:
1 Through PC
  PC will make use of the file system using mass storage driver.
2 Through device itself
  Device (uC) should be able to access read/write files from NAND flash.

Hope I have given the answers you are looking at. If not please free to ask.

Sorry to prod, but to answer you appropriately it would be helpful if 
you answer the question below:

Can you please explain the type of NAND flash you want to use? Is this 
raw flash chips? Or is this a NAND memory 'card' of some type like 
listed above?
