JRFLASH User Commands
jrflash - Flash File System (FFS) Utility
Part of the JNIOR File System is retained in Flash Memory. This is the
content of the /flash folder. This command displays the size of the
Flash and the amount of remaining space.
Displays statistics including the status of any cached data. The
writes_per_minute statistic may be used as an indication as to how
heavily the Flash is used. Flash components do have a finite life.
Formats the FFS. You will need to confirm the action. All data will
be lost. It is recommended that data be copied from the Flash first
if possible. It can then be restored.
Perform reclamation pass. Flash memory areas can be written once and
then must be reclaimed before being used again. The FFS utilizes all
of the available memory before reclaiming. The process is transparent
and happens in the background. This option allows you to manually
reclaim memory. This can greatly improve Flash performance in terms
of the average write time.
