eppfpga - Baycom EPP modem with FPGA configuration/diagnostics tool
eppfpga [ -vh ] [-p portaddr] [-m modestr] [-t test]
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.
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.
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
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
