7title: RedBoot FLASH Image System (FIS) Partitions
8
9description: The FLASH Image System (FIS) directory is a flash description
10    format closely associated with the RedBoot boot loader.
11    It uses one single flash eraseblock in the flash to store an index of
12    all images in the flash.
13    This block size will vary depending on flash but is typically
14    32 KB in size.
