nvmsplit(7) Qualcomm Atheros Powerline Toolkit nvmsplit(7)
NAME
nvmsplit - Qualcomm Atheros PLC Firmware Image File Slicer
SYNOPSIS
nvmsplit [options] file [file] [...]
DESCRIPTION
Extract all images from an Atheros binary image file, leaving the original files intact. Extracted images appear in
files having the input file basename with sequence numbers indicating the relative position of the image within the orig‐
inal file. For example, image file abc.nvm might result in files abc-00.nvm, abc-01.nvm, abc-02.nvm and so on. Each
output file is a valid, single-image file and so they can be combined using program nvmmerge.
Atheros image files consist of a chain of image headers, each followed by an image block. Image blocks can contain data,
applets or programs. Atheros software reads the header chain and decides which images to download and execute based on
information in the image headers. Tampering with image headers or images may void some contractual obligations made by
Atheros.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the AMP man page for an overview and installation
instructions.
OPTIONS
-q Suppress routine messages. This option has no effect at this time.
-v Print component file names on stderr as they are created.
-?,--help
Print program help summary on stdout. This option takes precedence over other options on the command line.
-!,--version
Print program version information on stdout. This option takes precedence over other options on the command line.
Use this option when sending screen dumps to Atheros Technical Support so that they know exactly which version of
the Linux Toolkit you are using.
ARGUMENTS
file The name of an Atheros image file. By convention, Atheros Image files have a .nvm file extension but this program
does not enforce this convention. Invalid image files will be rejected causing the output to be incomplete.
EXAMPLES
The following example reads Atheros image file abc.nvm and creates one or more output files. Each file contains one
image with associated header.
# nvmsplit abc.nvm -v
nvmsplit: abc.nvm --> abc-00.nvm
nvmsplit: abc.nvm --> abc-01.nvm
nvmsplit: abc.nvm --> abc-02.nvm
nvmsplit: abc.nvm --> abc-03.nvm
DISCLAIMER
Atheros image file structure and content is proprietary to Qualcomm Atheros, Ocala FL USA. Consequently, public informa‐
tion is not available. Qualcomm Atheros reserves the right to change file structure or content in future firmware
releases without any obligation to notify or compensate users of this program. This program is reserved for use by
Atheros Field Engineers. Use of this program may void some contractual obligations made by Atheros.
