NAME

       config2cfg - Atheros Configuration File Converter

SYNOPSIS

       config2cfg [options] file [file] [...]

DESCRIPTION

       The  config2cfg  program  converts  an SDRAM configuration file used by the Windows Device
       Manager to the configuration file format used by the Qualcomm Atheros Powerline Toolkit.

       This program is part of the Qualcomm Atheros Powerline Toolkit.  See the AMP man page  for
       an overview and installation instructions.

OPTIONS

       There are no options.

EXPLANATION

       The  Windows  Device  Manager  format  consists of 64 ASCII hexadecomal characters.  Files
       usually have a .config extension.  File size is at least 64 characters.  Excess characters
       are  ignored  in  input.   This means that files can be modified using any text editor and
       there is no way to detect modification.  From  a  programmin  standpoint,  ASCII-to-binary
       convertion and checksum computation is required on input and binary-to-ASCII conversion iw
       required on output.

       The Atheros Powerline Toolkit format consists of 32 binary bytes plus a 4  byte  (32  bit)
       checksum.   Files  usually have a .cfg extension.  File size is always 36 characters.  The
       files can be edited using any hex editor but a new checksum must be computed and  inserted
       after  any change.  No conversion or computation is required on input or output.  Input is
       ready for direct insertion into a VS_SET_SDRAM message.

       Programs int6k and int6kf expect this latter format  and  so  you  can  use  this  program
       determine if a given file has the proper format.

OPTIONS

       file   The filename of a Windows Device Manager SDRAM configuration file.  The file is re-
              written such that the filename is preserved but  the  contents  are  not.   Windows
              Device  Manager  SDRAM configuration files usually have a .config extension but the
              program makes no assumption based on filename and does  not  enforce  any  filename
              conventions.

       -q     Suppresses  printing  of progress messages.  There are no progress messages in this
              version.

       -v     Print additional information.  There is no additional information printed  in  this
              version.

       -?, --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.

EXAMPLES

       The  following  example  reads file abc.cfg and validates it.  The message shown indicates
       that the configuration file is the correct size and has a checksums and there are no  read
       errors.

           > chkcfg abc.cfg
           chkcfg: abc.cfg looks good

       The  following  example  reads three files in succession and reports on each one.  You can
       suppress good news with the -q option.

           # chkcfg abc.cfg def.cfg ghi.cfg
           chkcfg: abc.cfg looks good
           chkcfg: def.cfg is corrupt
           chkcfg: ghi.cfg looks good

       The following example displays the SDRAM configuration values in all  files  having  names
       that  match  the  wildcard  pattern sdram*.cfg.  We can confirm that the values inside are
       correct for their filenames.  Program output could have been sent to a file and saved  for
       later reference.

           # chknvm -qv sdram*.cfg
           ------- sdram32.cfg -------
                   SIZE=0x02000000 (32mb)
                   CONF=0x00143188
                   TIM0=0x01E1D491
                   TIM1=0x000883D6
                   CNTRL=0x00003089
                   REF=0x00000366
                   CLOCK=0x00000001
           ------- sdram16.cfg -------
                   SIZE=0x01000000 (16mb)
                   CONF=0x00142F68
                   TIM0=0x0115124E
                   TIM1=0x000883D6
                   CNTRL=0x00003089
                   REF=0x00000493
                   CLOCK=0x00000001
