Linux	Software Driver Installation

Installing the device

You connect a device to the driver with the mknod command. The major number is the number of the driver as shown in the last step, the minor number is the index of the board starting with 0. This step must only be done once for the system where the boards are installed in. The device will remain in the file structure even if the board is de-installed from the system.

The following command makes a device for the first Spectrum board the driver has found:

linux:~ # mknod /dev/spc0 c 254 0

Make sure that the users who work with the driver have full rights access for the device. Therefore you should give all persons all rights to the device:

linux:~ # chmod a+w /dev/spc0

Now it is possible to access the board using this device.

Driver info

Information about the installed boards could be found in the /proc/spectrum file. All PCI, PXI and CompactPCI boards show the basic infor- mation found in the EEProm there. This is an example output generated by a MI.3020:

linux:~ # cat /proc/spectrum

Spectrum driver information

---------------------------

Driver Version: 3.07 build 0

Board#0: MI.3020

serial number: 01234

production month: 05/2004

version:9.6

samplerate: 100 MHz

installed memory: 16 MBytes

Automatic load of the driver

It is necessary to load the kernel driver module after each start of the system before using the boards. Therefore you may add the „insmod spc.o“ command in one of the start-up files. Or you may load the kernel driver module manually whenever you need access to the board.
