+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.

+ description: a index to the eraseblock containing the FIS directory on this
+ device. On a flash memory with 32KB eraseblocks, 0 means the first
+ eraseblock at 0x00000000, 1 means the second eraseblock at 0x00008000 and so on.
