NAME

       eppfpga - Baycom EPP modem with FPGA configuration/diagnostics tool

SYNOPSIS

       eppfpga [ -vh ] [-p portaddr] [-m modestr] [-t test]

DESCRIPTION

       eppfpga is the configuration and diagnostics utility for the Baycom EPP
       modem.  It can be used to download the FPGA ‘‘firmware’’ or to  execute
       various tests.  This utility is also needed during ifconfig bcex up and
       therefore should reside in /sbin.

OPTIONS

       eppfpga accepts the following options:

       -h     Display an overview of the available command line parameters and
              exit.

       -v     Increases the verbosity of the output. May be cumulated.

       -p     Specifies  the  base address of the EPP capable parallel port to
              which the modem is connected.  Use  the  0x  prefix  to  specify
              hexadecimal numbers.

       -m     Specifies various ‘‘firmware’’ options.

       -t     Execute the named test. Tests may be stopped by pressing CTRL-C.

FIRMWARE OPTIONS

       intclk uses FPGA internal clock; dont use if an external oscillator is
              on board.

       extclk uses  the external oscillator; recommended if the internal modem
              is used, as the frequency of the FPGA oscillator is not accurate
              enough.

       intmodem
              uses the internal modem

       extmodem
              uses  a  DF9IC  type  modem  connected  to  the high speed modem
              connector

       divider=x
              sets   the   clock    divider    for    the    internal    modem
              (baud=fquartz/16/divider)

       loopback
              sets an internal modem loopback

       extstat
              allows extended status readback

       noextstat
              disallows extended status readback

       pttmute
              mutes modulation signal output when PTT is off (default)

       nopttmute
              modulation signal is continuously output

TESTS

       ram    tests the on board SRAM using boundary scan

       bled   tests  the  on  board  LED’s using boundary scan; disconnect PTT
              during the test.

       dac    tests the on board DAC using boundary scan

       led    tests the CON and STA leds using EPP address write

       ledfast
              tests the CON and STA leds using fast EPP address write

       berr   performs a BER test using  the  complete  adapter.  An  external
              loopback is required.

       berrv  performs  a BER test using the complete adapter. Also prints out
              the received bits. An external loopback is required.

       ccnt   frequency counter using the check firmware

       cdac   fast DAC test using the check firmware

       cram   fast RAM test using the check firmware

       cled   LED test using the check firmware
