We are using comedi to address two boards (ni_pcidio and daqboard2000) using a
commercial process control software. I just went over the procedure to get it
working on SuSE 10.0. The ni_pcidio is working, the daq we haven't tested
yet. Here is what I do:
1. Prepare the system
- install packages kernel-source, make and automatically
selected depending packages
- install package ncurses-devel (needed for make menuconfig)
- run online update to bring installed packages to current level
- reboot in case the kernel got updated
- become root ("su")
- copy configuration of currently running kernel to source tree:
"zcat /proc/config.gz > /usr/src/linux/.config"
- "cd /usr/src/linux"
- "make menuconfig", don't change anything, just exit
with save configuration
1a. compile and install kernel
- compile kernel:
"make clean"
"make bzImage"
- compile kernel modules:
"make modules"
- install kernel:
"cp /boot/vmlinuz /boot/vmlinuz.old"
"cp arch/i386/boot/bzImage /boot/vmlinuz"
- install modules:
"make modules_install"
- install new System.map:
"cp System.map /boot/"
- clean up (not required, but saves space):
"make clean"
- add line for old kernel in /boot/grub/menu.lst:
title Old Kernel
kernel (hd0,1)/boot/vmlinuz.old root=/dev/hdc2 vga=0x317 splash=silent
desktop showopts
initrd (hd0,1)/boot/initrd
- shut down the computer and reboot with the new kernel
2. Compile/install comedi kernel modules (cvs snapshot)
- unpack comedi to a location of your choice, you don't need to
be root for this: "tar xvfz comedi.tar.gz"
- as root, descend into the unpacked directory: "cd comedi/"
- create configuration files: "./autogen.sh"
- configure the sources without pcmcia: "./configure --disable-pcmcia"
- "make" to compile everything
- "make install" to install the comedi kernel modules
- "depmod -a" to create module dependencies
- "make dev" to created devices
3. Compile/install comedi userspace library
- unpack comedi library: "tar xvfz comedilib.tar.gz"
- as root, descend into the unpacked directory: "cd comedilib/"
- create configuration files: "./autogen.sh"
- configure the sources: "./configure --disable-pcmcia"
- "make" to compile everything
- "make install"
4. Load the comedi driver for the ni_pcidio board
- as root, load the pcidio kernel module: "/sbin/modprobe ni_pcidio"
- "/usr/local/sbin/comedi_config /dev/comedi0 ni_pcidio"
- test that the kernel module is loaded correctly: "lsmod"
you should get something like
Module Size Used by Not tainted
