.SH NAME
|
|
mkimage \- Generate image for U-Boot
|
|
.SH SYNOPSIS
|
|
.B mkimage
|
|
.RB [\fIoptions\fP]
|
|
.SH "DESCRIPTION"
|
|
The
|
|
.B 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.
|
|
|
|
.B mkimage
|
|
supports two different formats:
|
|
|
|
The old,
|
|
.I 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,
|
|
.I FIT (Flattened Image Tree) format
|
|
allows for more flexibility in handling images of various and also
|
|
enhances integrity protection of images with stronger checksums.
|
|
|
|
.SH "OPTIONS"

|
|
|
|
.TP
