Reference this information to ensure you install the correct NI Linux Real-Time base system image version when preparing an offline installation of VeriStand.
For programming environment selection, the environment should be compatible with the VeriStand release for that year. For example, if using VeriStand 2021, the programming environment should be 2021.
Note: Using versions of software that NI has not tested together may result in errors or incorrect behavior.
A base system image is an installation of the minimum amount of software needed to configure, install software to, and successfully use all available features with a Linux Real-Time Controller. This image is required to format and provision most NI real-time controllers to run the NI Linux Real-Time OS. You must update the base system image to install the latest drivers to your NI real-time controller.
Use NI Measurement & Automation Explorer (MAX) to format any Linux Real-Time compatible controller with the desired base system image. In addition to applying the selected base system image, this operation will remove all user data and software. Follow these step-by-step instructions on the Installing Software on NI Linux Real-Time PXI Controllers page to format your controller and apply a new base system image.
The following table displays which versions of the base system image were used when testing each VeriStand release.
