修正できないエラーメッセージが表示されたときにチュートリアルがほぼ終了しました。

# mkimage -f script xen-chromebook-image
Error: script:7.15-16 syntax error
FATAL ERROR: Unable to parse input tree
mkimage: Can't open xen-chromebook-image.tmp: No such file or directory
Error: Bad parameters for FIT image type
Usage: mkimage [-T type] -l image
-l ==> list image header information
-T ==> parse image file as 'type'
-q ==> quiet
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
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
-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
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
