Hi

If you want to use the internal flash for firmware upgrading a FAT file system would normally be 'over-kill' and very inefficient.

Firmware upgrading can be performed without any file system by simply copying the code to its execution location.

See the following with the Kinetis (it also works on the M52259) http://www.youtube.com/watch?v=H4TYM9jY2-g

It has serial upload support which simply copies directly to the flash location and it has USB MSD upload, whereby the PC is 'fooled' to believe that there is a FAT file system but it doens't need to use one to it.
