Offline Installation

If a machine lacks Internet access and cannot reach online files, you can create an offline image and manually copy it to use on that machine:

  • Start the installer on a machine connected to the internet

  • Select the components that you want to install on the offline machine (example: select LinkServer and Arm GNU Toolchain)

  • Create the offline image from the Options menu. Select Create offline images -> choose the desired target host OS:

MCUXpresso Installer - Create offline image

  • Wait for the image to finish being created. This status is indicated in the MCUXpresso Installer console along with the steps needed to use the image:

    • Copy all files from an online machine directory: MCUXpressoInstaller layout/.cache/offline/desired target host OS.

    • Paste all files to the target offline machine directory: MCUXpressoInstaller layout/.cache.

    • Start MCUXpresso Installer on the target machine and select and install the components as created in the offline image.

Note: Some installation steps (the ones requiring active internet connection at install) are not included in the offline image (example: Python modules). The current offline image functionality does not address these components.
