nilsdev finds nothing, error -52026

[cobas]

Hi all,

Under Scientific Linux 6, x86_64, nlsdev reports no devices.

$ nilsdev -v
-52026
Error code could not be found. Reinstalling the driver might fix the issue. Otherwise, contact National Instruments technical support.

However, six PXI 5122 are there:

$ lspci |grep National
08:0a.0 Unassigned class [ff00]: National Instruments PXI-5122 (rev 01)
08:0c.0 Unassigned class [ff00]: National Instruments PXI-5122 (rev 01)
08:0e.0 Unassigned class [ff00]: National Instruments PXI-5122 (rev 01)
09:0c.0 Unassigned class [ff00]: National Instruments PXI-5122 (rev 01)
09:0e.0 Unassigned class [ff00]: National Instruments PXI-5122 (rev 01)
0a:0a.0 Unassigned class [ff00]: National Instruments PXI-5122 (rev 01)

Drivers seem to be correctly installed:

[...]

and, moreover, the PCI devices are correctly recognized by the driver, as seen under sysfs:

I have gone crazy trying to understand what's missing. In case it helps, I attach herewith strace's of the execution of nilsdev -v in this machine, where it fails to find anything, and of another where the same software is installed verbatim, and three PXI 5122 modules are detected by nilsdev -v.

Any suggestion?

Which driver version are you using?

You already tried reinstalling the driver?

So you have other DAQ devices that are recognized properly? 

I was doing some research about the NI PXI-5122 and the target OS is Windows. But you could work with the NI SCOPE driver for linux for this device. Do you have this driver installed?

It is NIScope under Linux what I have installed.

The problem with nilsdev turns out to be simply caused by the absence of

/acc/sys/L866/var/local/natinst/NI-DAQmx/locks
/acc/sys/L866/var/local/natinst/NI-DAQmx/locks/nidaqmxSystemStorageWrite.lock
/acc/sys/L866/var/local/natinst/NI-DAQmx/locks/nidaqmxSystemStorageRrWr.lock

Note that no meaningful error is given when nilsdev exits:

$ nilsdev -v
-52026
Error code could not be found. Reinstalling the driver might fix the issue. Otherwise, contact National Instruments technical support.

Now that this has been overcome, yet another problem arises: when two processes access a board concurrently, my machine gets a hard freeze (no ping, no ssh, nothing... and of course no trace in the kernel ringbuffer).

Hi,

Since you are having issues with NI SCOPE and NI hardware I recommend posting your question on this forum: http://forums.ni.com/t5/High-Speed-Digitizers/bd-p/150 instead of Multifunctional DAQ.
