NAME
int64host - INT6400 Host Emulator
SYNOPSIS
int64host [options] -N file -P file -n file -p file
DESCRIPTION
The INT6400 Host Emulator waits for VS_HST_ACTION.IND messages from a local device and services them as
described in the INT6400 Technical Reference Manual. It can be used to demonstrate or verify proper
device/host interaction for flash-less devices. This program is not production grade and will stop dead
- like a bug! - when things go wrong. Use the Qualcomm Atheros Embedded API for real-time, production-
grade applications.
Host emulation applies to flash-less device designs where a local host processor provides the persistent
storage. The local host can provide a wide range of intelligent storage functions for a device but this
program offers one. Options -N and -P name existing files that store the factory default runtime
firmware and parameters, respectively. Options -n and -p name scratch files that will store user
firmware and parameters, respectively. This is similiar to the standard Atheros NVRAM scheme but is not
the same.
To use the program, connect a flash-less device to the host via ethernet then start this program with the
correct filenames. The program will automatically respond to device requests to download memory
configuration, firmware and/or parameters and upload firmware or and/or parameters under device control.
See the Qualcomm Atheros Firmware Technical Reference Manual for more information.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the plc man page for an overview and
installation instructions.
OPTIONS
-F[F] Flash NVRAM once downloaded firmware has started. The same firmware and PIB are downloaded,
again, using VS_WR_MOD and written to NVRAM using VS_MOD_NVM. Adding a second F here or another
-F anywhere on the command line will perform a forced flash. When no NVRAM is present, normal and
force flash cause the device to upload to the host. When blank or corrupted NVRAM is present,
forced flash writes to NVRAM. This operation will fail when no NVRAM is present.
-i interface
Select the host Ethernet interface. All requests are sent via this host interface and only
reponses received via this host interface are recognized. The default interface is eth1 because
most people use eth0 as their principle network connection; however, if environment string "PLC"
is defined then it takes precedence over the default interface. This option then takes precedence
over either default.
-N filename
Use this file to download firmware when requested by the local device. The file must exist and
have a valid NVM file format or it will be rejected. No assumptions are made based on filename
and no filename conventions are enforced. The program will not over-write this file. This option
and argument are required.
-n filename
Use this file to store firmware uploaded from the local device. The file need not exist but an
error will occur if it cannot be created or written. If firmware is uploaded to this file, it is
used for subsequent firmware downloads unless the device requests a factory reset. In that case,
the file specified by option -N is used. This option and argument are optional. If omitted then
the default filename host.pib will be used.
-P filename
Use this file to download parameters when requested by the local device. The file must exist and
have a valid PIB file format or it will be rejected. No assumptions are made based on filename
and no filename conventions are enforced. The program will not over-write this file. This option
and argument are required.
-p filename
Use this file to store parameters uploaded from the local device. The file need not exist but an
error will occur if it cannot be created or written. Once parameters are uploaded to this file,
it is used for subsequent parameter downloads unless the device requests a factory reset. In that
case, the file specified by option -P is used. This option and argument are optional. If omitted
then the default filename host.nvm will be used.
-q Suppress status messages on stderr.
-t milliseconds
Read timeout in milliseconds. Values range from 0 through UINT_MAX. This is the maximum time
allowed for a response. The default is shown in brackets on the program menu.
-v Print additional information on stdout. In particular, this option will print incoming and
outgoing Ethernet frames on stdout.
-?, --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
None.

EXAMPLES
The following command starts the host emulator. The -N and -P options are always required. Their order
is not important.
