Other file systems are not recommended because only NXFFS can handle
bad blocks and only NXFFS performs wear-leveling.
NOTE: NXFFS is very slow. The first time that you start the system,
be prepared for a long wait. I have lots of debug on so I don't know
what the optimized wait will be. But with debug ON, the wait is in
units of hours.
NOTE: There is another NXFFS related issue: When the FLASH is
fully used, NXFFS will restructure the entire FLASH, the delay to
restructure the entire FLASH will probably be even larger. This
solution in this case is to implement an NXFSS clean-up daemon that
does the job a little-at-a-time so that there is no massive clean-up
when the FLASH becomes full.
