  • The Status LED on my cRIO is continuously flashing and I am unable to boot into the device.

This error message indicates a problem with one of the following:
  • The primary flash storage on the controller.
  • The software installed on the controller.
This article will detail the steps to check the default boot device and restore the device to factory default.

Checking the boot device

  1. Reboot the target and enter the BIOS configuration by pressing <F10> or <DEL> while booting.
  2. Navigate to the BIOS configuration boot options.
    • Refer to the device's User Manual for details on how to navigate the BIOS settings.
  3. Verify that the onboard storage is present and selected as a boot option.
