fis create


fis create -- Create flash image


fis create {-b data address} {-l length} [-f flash address] [-e entry] [-r relocation address] [-s data length] [-n ] [name]


-bNumberAddress of data to be written to the flash.Address of last loaded file. If not set in a load operation, it must be specified.
-lNumberLength of flash area to occupy. If specified, and the named image already exists, the length must match the value in the FIS directory.Length of area reserved in FIS directory if the image already exists, or the length of the last loaded file. If neither are set, it must be specified.
-fNumberAddress of flash area to occopy.The address of an area reserved in the FIS directory for extant images. Otherwise the first free block which is large enough will be used.
-eNumberEntry address for an executable image, used by the fis load command.The entry address of last loaded file.
-rNumberAddress where the image should be relocated to by the fis load command. This is only relevant for images that will be loaded with the fis load command.The load address of the last loaded file.
-sNumberActual length of data written to image. This is used to control the range over which the checksum is made.It defaults to the length of the last loaded file.
-n When set, no image data will be written to the flash. Only the FIS directory will be updated. 
nameStringName of flash image. 


This command creates an image in the FIS directory. The data for the image must exist in RAM memory before the copy. Typically, you would use the RedBoot load command to load file into RAM and then the fis create command to write it to a flash image.


Trying to create an extant image, will require the action to be verified.

RedBoot> fis create RedBoot -f 0xa0000000 -b 0x8c400000 -l 0x20000
An image named ‘RedBoot’ exists - continue (y/n)? n

Create a new test image, let the command find a suitable place.

RedBoot> fis create junk -b 0x8c400000 -l 0x20000

Update the RedBoot[RAM] image.

RedBoot> load redboot_RAM.img

RedBoot> fis create RedBoot[RAM]
No memory address set.
An image named 'RedBoot[RAM]' exists - continue (y/n)? y
