mkimage - Generate image for U-Boot
概要
- U-Boot で実行するファイルは、mkimage というコマンドで U-Boot 用のフォーマット(uImage)に変換する
- encapsulates a compressed "uImage" Linux kerel image with header information, CRC32 checksum, etc, for use with the U-Boot bootloader.
- mkimage can also be used to create ramdisk images for use with U-Boot, either separated from the Linux kernel image, or combined into one file. mkimage encapsulates the images with a 64 byte header containing information about target architecture, operating system, image type, compression method, entry points, time stamp, CRC32 checksums, etc.

使い方
$ mkimage
Usage: mkimage -l image
-l ==> list image header information
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 fit-image
mkimage -V ==> print version information and exit
例
mkimage -A arm -O linux -T kernel -C gzip -a 30008000 -e 30008000 -n "Kernel Image" -d linux.bin.gz uImage.bin

NAME
mkimage - Generate image for U-Boot
SYNOPSIS
mkimage [options]
DESCRIPTION
The mkimage command is used to create images for use with the U-Boot
boot loader. Thes eimages can contain the linux kernel, device tree
blob, root file system image, firmware images etc., either separate or
combined.
mkimage supports two different formats:
The old, legacy image format concatenates the individual parts (for
example, kernel image, device tree blob and ramdisk image) and adds a
64 bytes header containing information about target architecture, oper‐
ating system, image type, compression method, entry points, time stamp,
checksums, etc.
The new, FIT (Flattened Image Tree) format allows for more flexibility
in handling images of various and also enhances integrity protection of
images with stronger checksums.
OPTIONS
List image information:
-l [uimage file name]
mkimage lists the information contained in the header of an
existing U-Boot image.
Create old legacy image:
-A [architecture]
Set architecture. Pass -h as the architecture to see the list of
supported architectures.
-O [os]
Set operating system. bootm command of u-boot changes boot
method by os type. Pass -h as the OS to see the list of sup‐
ported OS.
-T [image type]
Set image type. Pass -h as the image to see the list of sup‐
ported image type.
-C [compression type]
Set compression type. Pass -h as the compression to see the
list of supported compression type.
-a [load addess]
Set load address with a hex number.
-e [entry point]
Set entry point with a hex number.
-n [image name]
Set image name to 'image name'.
-d [image data file]
Use image data from 'image data file'.
-x Set XIP (execute in place) flag.
Create FIT image:
-D dtcoption"
Provide special options to the device tree compiler that is used
to create the image.
-f fit-image.its"
Image tree source fine that descbres the structure and contents
of the FIT image.
EXMAPLES
List image information:
mkimage -l uImage
Create legacy image with compressed PowerPC Linux kernel:
mkimage -A powerpc -O linux -T kernel -C gzip \
-a 0 -e 0 -n Linux -d vmlinux.gz uImage
Create FIT image with compressed PowerPC Linux kernel:
mkimage -f kernel.its kernel.itb
