NI provides a repository add-on for all supported drivers that you can install using your Linux distribution's native package manager.
After the driver packages are installed, you must rebuild the new packages for the system kernel. NI recommends that you run the command 'dkms autoinstall' after installation, and before rebooting the system, to install the latest revision of all modules that have been installed for other kernel revisions. After doing so, the installed device drivers will function immediately on the next system start.
You must begin development on a computer running Windows.
To find the FlexRIO device you are using in your application, use the command 'lsni -v' to list information on all National Instruments devices in the system.
Some features discussed in the FlexRIO documentation are unavailable on Linux.
The following FlexRIO driver features supported for Windows are not supported for Linux.
You must compile a bitfile using LabVIEW FPGA on a Windows machine. Refer to the "Using the FlexRIO Driver and FPGA Interface C API" section for more information.
