Where is the register-level spec for the NI-4462?

[RichardNeiill]

Hi - yes, I agree it's ugly. It may not be that evil: also, I do know the kernel developer who assisted me with it, and I would imagine that for a day's consultancy, he could probably make the driver work with a current kernel if you wanted. Alternatively, you can (usually) get an older kernel to run with a more modern distro.

Meanwhile, I hope my "lab" notes on the device were useful - I spent a very long time working with itl.

Also, if it's helpful, I wrote quite a lot of userspace programs for dumping data - you may find these helpful - especially as I spent a very long time debugging some of the quirks out of it.

Was this private discussion fruitful? Did it lead to any advances in building a driver compatible with modern linux kernels?

There hasn't been any progress on the 446x DDK, so please contact your local NI field engineer to explore options.

NI-KAL continues to support newer 32-bit Linux distributions and their kernels:

• Red Hat Enterprise Linux Workstation 7
• Red Hat Enterprise Linux Workstation 6
• Scientific Linux 7
• Scientific Linux 6
• openSUSE 13.1
• openSUSE 12.3
• openSUSE 12.2

When using DAQmx 8.0 for Linux, install NI-KAL 14.0 first.

Hello all,

I am trying to set up DAQmx on OpenSUSE 13.1.

I tried to install NIKAL 14 first, as advised. The installation completed successfully.

However, installation of DAQmx then failed, apparently mostly due to conflicts with what was installed by NIKAL, i.e.:

Installing NI-DAQmx for Linux Installer Distribution version 8.0.2f0...

Any idea ?

Thanks

This looks like the DAQmx 8.0.2 installer and the KAL 14.0 installer try to place the same files in the same location.

If this is the case, you will need to modify the DAQmx INSTALL script to workaround the problem. Line 903 sets the options used when invoking rpm to the variable RPMOpts; try adding --replacefiles to it, which will instruct rpm to install the packages even if they replace files from other, already installed, packages.

Hum, ok, thanks for the suggestion. 

The problem would be that it means that newer files from KAL 14.0 will be overriden by old files from DAQmx 8.0.2. I am not sure how wise that is. Therefore, KAL 14 should be reinstalled afterwards using the same trick.

As a side note, I tried to install VISA and DAQmx Base as well, but I am stuck because of the lack of libstdc++.so.5 on OpenSUSE 13.2. It only has libstdc++.so.6 and libstdc++.so.2.9, as well as libc6 variants. Unfortunately there is no compat-libstdc++ package on OpenSUSE 13.2. It is my understanding that libstdc++.so.5 comes from gcc-3.3.x, which is fairly old. Any chance to get a version of VISA compiled against gcc-4 instead ? Or do you guys know where to find compatibility versions of libstdc++ for OpenSUSE 13.2 ?

I tried to compile gcc-3 myself with no luck so far...

For OpenSuSE 13.2, VISA 14.0 may work since it is compiled with gcc 4.2.1. However, DAQmx Base 14.0 is compiled with gcc 3.2, so I don't expect it will work.

Are you trying to install all of the drivers as an experiment, or do you have specific hardware that requires DAQmx Base and VISA?

I use this computer with GPIB-USB adapter and a PCI-PXI controller. I think DAQmx Base may suffice if DAQmx does not install, though I am not sure about that, since I always used DAQmx for my PXI controllers.

You are right that a new thread should be created.

I get an error with VISA related to libstdc++.so.5:
