NAME
ubinize - a tool for generating UBI images
SYNOPSIS
ubinize [-o filename] [-p <bytes>] [-m <bytes>] [-s <bytes>] [-O <num>]
[-e <num>] [-x <num>] [-Q <num>] [-v] [-h] [-V] [--output=<filename>]
[--peb-size=<bytes>] [--min-io-size=<bytes>] [--sub-page-size=<bytes>]
[--vid-hdr-offset=<num>] [--erase-counter=<num>] [--ubi-ver=<num>]
[--image-seq=<num>] [--verbose] [--help] [--version] ini-file
DESCRIPTION
An UBI image may contain one or more UBI volumes which have to be
defined in the input configuration ini-file. The ini file defines all
the UBI volumes - their characteristics and the contents, but it does
not define the characteristics of the flash the UBI image is generated
for. Instead, the flash characteristics are defined via the command-
line options. Note, if not sure about some of the command-line parame‐
ters, do not specify them and let the utility use default values.
OPTIONS
-o, --output=file
Specify output file
-p, --peb-size=bytes
Size of the physical eraseblock of the flash this UBI image is
created for in bytes, kilobytes (KiB), or megabytes (MiB). This
parameter is mandatory.
-m, --min-io-size=bytes
Minimum input/output unit size of the flash in bytes
-s, --sub-page-size=bytes
Minimum input/output unit used for UBI headers, e.g. sub-page
size in case of NAND flash (equivalent to the minimum input/out‐
put unit size by default).
-O, --vid-hdr-offset=num
Offset if the VID header from start of the physical eraseblock
(default is the next minimum I/O unit or sub-page after the EC
header)
-e, --erase-counter=num
The erase counter value to put to EC headers (default is 0).
-x, --ubi-ver=num
UBI version number to put to EC headers (default is 1).
-Q, --image-seq=num
32-bit UBI image sequence number to use (by default a random
number is picked).
-v, --verbose
Be verbose.
-h, --help
Print a help message and exit.
-V, --version
Print program version and exit.
EXAMPLE
ubinize -o ubi.img -p 16KiB -m 512 -s 256 cfg.ini
Create UBI image ubi.img as described by configuration file cfg.ini.
A physical erase block on the flash is 16KiB in size and has 512 byte
pages with 256 byte sub-pages.
INI-FILE FORMAT
The input configuration ini-file describes all the volumes which have
to be included to the output UBI image. Each volume is described in its
own section which may be named arbitrarily. The section consists on
"key=value" pairs, for example:
[jffs2-volume]
mode=ubi
image=../jffs2.img
vol_id=1
vol_size=30MiB
vol_type=dynamic
vol_name=jffs2_volume
vol_flags=autoresize
vol_alignment=1
This example configuration file tells the utility to create an UBI
image with one volume with ID 1, volume size 30MiB, the volume is
dynamic, has name jffs2_volume, autoresize volume flag, and alignment
1.
The image=../jffs2.img line tells the utility to take the contents of
the volume from the ../jffs2.img file. The size of the image file has
to be less or equivalent to the volume size (30MiB).
The mode=ubi line is mandatory and just tells that the section
describes an UBI volume - other section modes may be added in the
future.
Notes:
· Size in vol_size might be specified kilobytes (KiB), megabytes
(MiB), gigabytes (GiB) or bytes (no modifier).
· If "vol_size" key is absent, the volume size is assumed to be
equivalent to the size of the image file (defined by "image" key).
· If the "image" is absent, the volume is assumed to be empty
· Volume alignment must not be greater than the logical eraseblock
size.
· One ini file may contain arbitrary number of sections, the utility
will put all the volumes which are described by these section to
the output UBI image file.
