eppfpga8
Baycom epp modem with fpga configuration/diagnostics tool
Usage
eppfpga [-vh]
[-p
portaddr]
[-m
modestr]
[-t
test]
Overview
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.
Options
intclk-
uses FPGA internal clock;
don'tuse 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
