initialize CAN kernel modules for GPSD

Synopsis

gpsinit [-n control] [-s speed] module_name [interface_name]

gpsinit -h

gpsinit -V

Description

gpsinit initializes whatever kernel-level modules are needed to enable special non-serial hardware to communicate with a gpsd instance. Note: it will need root permissions to load modules and perform other special operations, such as changing kernel-interface baudrates.

At present, all modes of this tool are concerned with setting up kernel-level interfaces to hardware on a CAN (Control Area Network) speaking NMEA2000.

The program accepts the following options:

-h

Display a brief help text.

-n

Set the CAN network number. The default is 0.

-s

Set the baudrate to be used to communicate over the serial line to the CAN hardware. The default is 38400 baud.

-V

Display the version of gpsinit.

The parameter module_name is mandatory. The socket CAN driver module module_name.ko will be loaded. gpsinit recognize the following module names:

plx_pci,  esd_usb2,  vcan,  slcan

The parameter interface_name and -s speed can used here.

beaglebone

The dcan module needed for the beaglebone is part of the Linux kernel, so no module is loaded in this case.

The parameter interface_name is needed for slcan hardware only. It gives the name of the serial device to which the SL CAN hardware is connected. The default is /dev/ttyUSB0.

Examples

All the following examples probably need to be run as root.

gpsinit plx_pci

Attempt to load the module plx_pci and initialize net 0 for the connection to a NMEA2000 network. It will set the baudrate to 250kBits.

gpsinit -n 1 plx_pci

As above, but use net 1.

gpsinit -s 38400 slcan /dev/ttyUSB0

Attempt to load the module slcan and talk to the hardware at 38400 baud connected to port /dev/ttyUSB0.

gpsinit -h

Display a brief help message.

gpsinit -v

Display the version of gpsinit.

Return Values

0

on success.

1

on failure
