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 exe-
cute 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 hexadeci-
mal 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; don't 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
