— Free flash image

Synopsis

fis free

Description

This command shows which areas of the flash memory are currently not in use. When a block contains non-erased
contents it is considered in use. Since it is possible to force an image to be loaded at a particular flash location, this
command can be used to check whether that location is in use by any other image.

Note: There is currently no cross-checking between actual flash contents and the FIS directory, which mans
that there could be a segment of flash which is not erased that does not correspond to a named image, or
vice-versa.

Examples
