Hey,
I am trying to get a national instrument data acquisition pci card working
under linux 2.6.30.5 xenomai 2.5-rc3 using comedi. I successfully installed
the regular comedi drivers and I got data from the card, however, I also got
mode switches. Therefore, I moved to the latest xenomai release which
includes the comedi interface. The installation worked out and I got a
xeno_comedi.ko module that I can load and a /usr/xenomai/lib/libcomedi.so.0.
However, my program returns with...
xenomai:~/xenomai_test> ./rt_comedi_test
./rt_comedi_test: /usr/xenomai/lib/libcomedi.so.0: no version information
available (required by ./rt_comedi_test)
Xenomai: incompatible ABI revision level
(needed=1, current=2).
I figured, that I need a national instrument driver (ni_pcimio) to get the
/dev/comedi0 up and running since there is no kernel module associated with
the NI card...
xenomai:~/xenomai_test> lspci -v
...
06:00.0 Class ff00: National Instruments Device 717f
Flags: bus master, medium devsel, latency 64, IRQ 11
Memory at f7dfe000 (32-bit, non-prefetchable) [size=4K]
Memory at f7dff000 (32-bit, non-prefetchable) [size=4K]
...
I "svn co http://svn.gna.org/svn/xenomai/branches/comedi-rtdm-dev"; since it
seems to contain the NI drivers... however, I got a compiler error that I
think relates to the fact that the system I am using has 4GB of ram
(highmem). I am using revision: 4727.

I would be really happy if someone could give me some hints/advice on how to
get things working. What do I need to do ??
Thanks a lot,
peter
