All errors (new ones prefixed by >>):

>> Error: Invalid compression type
   Usage: /usr/bin/mkimage [-T type] -l image
   -l ==> list image header information
   -T ==> parse image file as 'type'
   -q ==> quiet
   /usr/bin/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'
   -R ==> set second image name to 'name'
   -d ==> use image data from 'datafile'
   -x ==> set XIP (execute in place)
   -s ==> create an image with no data
   -v ==> verbose
   /usr/bin/mkimage [-D dtc_options] [-f fit-image.its|-f auto|-f auto-conf|-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
   -b => append the device tree binary to the FIT
   -t => update the timestamp in the FIT
   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 => set key name hint
   -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
   -o => algorithm to use for signing
   /usr/bin/mkimage -V ==> print version information and exit
   Use '-T list' to see a list of available image types
   Long options are available; read the man page for details
