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 file‐
names. 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 parame‐
ter 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 impor‐
tant.
