dumpimage
[email protected]:~# dumpimage --help
dumpimage: invalid option -- '-'
Usage: dumpimage [-T type] -l image
          -l ==> list image header information
          -T ==> parse image file as 'type'
       dumpimage [-T type] [-p position] [-o outfile] image
          -T ==> declare image type as 'type'
          -p ==> 'position' (starting at 0) of the component to extract from image
          -o ==> extract component to file 'outfile'
       dumpimage -h ==> print usage information and exit
       dumpimage -V ==> print version information and exit

kwboot

[email protected]:~# kwboot -h
kwboot version 2022.04+dfsg-2+b1
Usage: kwboot [OPTIONS] [-b <image> | -D <image> | -b | -d ] [-B <baud> ] [-t] <TTY>

  -b <image>: boot <image> with preamble (Kirkwood, Avanta, Armada 370/XP/375/38x/39x)
  -D <image>: boot <image> without preamble (Dove)
  -b: enter xmodem boot mode
  -d: enter console debug mode
  -a: use timings for Armada XP
  -s <resp-timeo>: use specific response-timeout

	-g, --guid <guid string>    guid for image blob type
	-i, --index <index>         update image index
	-I, --instance <instance>   update hardware instance
	-p, --private-key <privkey file>  private key file
	-c, --certificate <cert file>     signer's certificate file

mkenvimage

mkimage

Generate image for U-Boot

[email protected]:~# mkimage -h
mkimage: invalid option -- 'h'
Error: Invalid option
Usage: mkimage [-T type] -l image
          -l ==> list image header information
          -T ==> parse image file as 'type'
       mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image
          -A ==> set architecture to 'arch'
          -O ==> set operating system to 'os'
          -T ==> set image type to 'type'
          -C ==> set compression type 'comp'
          -a ==> set load address to 'addr' (hex)
          -e ==> set entry point to 'ep' (hex)
          -n ==> set image name to 'name'
          -d ==> use image data from 'datafile'
          -x ==> set XIP (execute in place)
       mkimage [-D dtc_options] [-f fit-image.its|-f auto|-F] [-b <dtb> [-b <dtb>]] [-E] [-B size] [-i <ramdisk.cpio.gz>] fit-image
           <dtb> file is used with -f auto, it may occur multiple times.
          -D => set all options for device tree compiler
          -f => input filename for FIT source
          -i => input filename for ramdisk file
          -E => place data outside of the FIT structure
          -B => align size in hex for FIT structure and header
Signing / verified boot options: [-k keydir] [-K dtb] [ -c <comment>] [-p addr] [-r] [-N engine]
          -k => set directory containing private keys
          -K => write public keys to this .dtb file
          -G => use this signing key (in lieu of -k)
          -c => add comment in signature node
          -F => re-sign existing FIT image
          -p => place external data at a static position
          -r => mark keys used as 'required' in dtb
          -N => openssl engine to use for signing
       mkimage -V ==> print version information and exit
Use '-T list' to see a list of available image types
