libnipalu.so failed to initialize

[Yawgmoth]

hello!!

i'm trying to use a NI USB-6501 on a linux trustix distro with a custom kernel (2.6.23)....

i followed the setup procedure, that went on very smoothly, but when i try to use lsdaq  to check the equipment, i get this error:

libnipalu.so failed to initialize
Perhaps you need to run updateNIDrivers
/usr/local/bin/lsdaq: line 7:  4798 Aborted                 /etc/natinst/nidaqmxbase/bin/daqmxbase_listdevices

of course i tried to run updateNIDrivers, but even if it doesn't report any error, it doesn't fix the problem....

i checked the forum to see if others had already solved the same problems, but none of the suggested solutions worked for me....

this is the info i have about my system:

[root@vds-dev ~]# lsmod | grep ni
nidimk                345632  0
niorbk                 97364  1 nidimk

so..... it seems to be ok... the only thing that puzzles me is the output of dmesg:

i attached the output of niSystemReport 'cos it was too long to include in the post....

maybe the problem is that trustix doesn't use udev??

could it be that i need to create the device in the /dev/ folder manually??

let me know if you need more info...

thanks in advance!!

The NI drivers don't really use udev, though I seem to remember that udev might be used to load firmware on some of the USB devices.  The NI drivers do install several init scripts one being "/etc/init.d/nipal" and that init script will create /dev/nipalk.  If /dev/nipalk is missing you will get the error you are receiving so that may be your problem.

thanks Shawn!!

it leads to another question.... what are the major & minor numbers of the /dev/nipalk device??

The major number is dynamic and I think the minor is 0, but really you should just run the /etc/init.d/nipal init script since it does more than create the device node.

thanks again for the hint!!

it doesn't work yet, but it's still a step forward.... ^^

now i get another error:

[root@vds-dev ~]# /usr/local/bin/lsdaq
--------------------------------
Detecting National Instruments DAQ Devices
Found the following DAQ Devices:

Device Error: incompatible firmware.  Serial Number: 01468D80

Execute <NI-DAQmx Base directory>/bin/FWUpdate to update.
--------------------------------

and if i try to update the firmware with FWUpdate, it doesn't work 'cos i don't have xwindows installed.... lol

[root@vds-dev ~]# /usr/local/natinst/nidaqmxbase/bin/FWUpdate
Can't load LabVIEW runtime library /usr/local/lib/liblvrt.so.8.2
libX11.so.6: cannot open shared object file: No such file or directory

but at least now i know that i'm on the right path.....

[Yawgmoth]

problem solved!!

i installed xwindows, updated the firmware and now lsdaq detects the device!!

[root@vds-dev ~]# /usr/local/bin/lsdaq
--------------------------------

thanks a lot!!
