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, operating 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 supported OS.

       -T [image type]
              Set image type.  Pass -h as the image to see the list of supported 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
