Initialize can kernel modules for gpsd
gpsinit [-n control] [-s speed] module_name [interface_name] gpsinit -h gpsinit -v
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.
-v
Display the version of gpsinit.
-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.
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.
sudo 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.
sudo gpsinit -n 1 plx_pci
As above, but use net 1.
sudo 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.
