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