NAME

       plchostd2 - Qualcomm Atheros Panther/Lynx PLC Host Daemon

SYNOPSIS

       plchostd2 [options] -N nvmfile -P pibfile

DESCRIPTION

       Wait  for  VS_HST_ACTION.IND messages from a local device and service them as described in
       the Qualcomm Atheros Firmware Technical Reference Manual for  powerline  devices.   Unlike
       programs int6khost and int64host, this program uses operating system features available on
       POSIX, Unix, BSD and Linux systems but not available  on  Microsoft  or  VxWorks  systems.
       This program supports chipsets QCA6410, QCA7000 and QCA7420.

       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

       -i interface
              Select the host Ethernet interface.  All requests are sent via this  interface  and
              only reponses received via this 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 nvmfile
              The file containing the firmware chain used to boot and flash the 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 pibfile
              The file containing the parameter chain used to boot and  flash  the  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.

       -S filename
              The file containing the softloader chain used to flash the device.  The presence of
              this  file causes the device to be flashed once it has booted.  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.

       -t timeout
              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.

       -w wakeup
              Wakeup  time  in  seconds.  If no VS_HST_ACTION.IND message is received within this
              time period then the process will wakeup and perform  periodic  functions  such  as
              posting network topography to the server socket specified by option -s.

       -?, --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 example starts the host server.  The -N and -P options are always  required.
       Option  order  is not important.  Control does not return to the console until the program
       is terminated by the user using CTRL-C or another command line interrupt.

          # plchostd2 -N test.nvm -P test.pib -n temp.nvm -p temp.pib

       The next example does the same but spawns  the  program  as  an  independent  process  and
       returns  control  to the console.  In this case, that process must be terminated or killed
       using an appropriate command such ad kill.

          # plchostd2 -N test.nvm -P test.pib -n temp.nvm -p temp.pib -d
