Flash Image System (FIS)
If the platform has flash memory, RedBoot can use this for image storage. Executable images, as well as data, can
be stored in flash in a simple file store. The fis command (fis is short for Flash Image System) is used to manipulate
and maintain flash images.

Arguments
Name
Type
Description
Default
-f
All blocks of flash memory
(except for the boot blocks)
will be erased as part of the
initialization procedure.
Description
This command is used to initialize the Flash Image System (FIS). It should normally only be executed once, when
RedBoot is first installed on the hardware. If the reserved images or their sizes in the FIS change, due to a different
configuration of RedBoot being used, it may be necessary to issue the command again though.
Note: Subsequent executions will cause loss of previously stored information in the FIS.
Examples
Initialize the FIS directory.
