The --fill option specifies a value for filling the holes between sections. The fill value must be specified as an integer constant following the --fill option. The width of the constant is assumed to be that of a word on the target processor. For example, specifying --fill=0x0FF. The constant value is not sign extended.
The hex conversion utility uses a default fill value of 0 if you do not specify a value with the fill option. The --fill option is valid only when you use --image; otherwise, it is ignored.
