Linux Real-Time PXI Driver and Software Compatibility


Linux Real-Time for PXI is the latest Real-Time Operating System for NI PXI Controllers. With this change, support for many NI software products and drivers has changed. This document details supported drivers and software, caveats, support limitations, and other information on these changes.


Migrating to Linux Real-Time PXI

While existing controllers and applications can be migrated to Linux Real-Time PXI, there are several steps necessary. To migrate an application to Linux Real-Time on PXI:

  1. Provision a supported PXI Controller with NI Linux Real-Time as documented in Provisioning a PXI Controller to the NI Linux Real-Time Operating System.
  2. Install software to the PXI Linux Real-Time Controller as described in Installing Software on NI Linux Real-Time PXI Controllers.
  3. Review the Real-Time Module on NI Linux Real-Time Targets topic in the LabVIEW Real-Time Module Help for comparisons to and differences from previous Real-Time Operating Systems.
