Issue Details

My sbRIO Status LED is blinking on and off in a continuous fashion. The user manual tells me "The chassis has detected an unrecoverable error. Contact National Instruments." Power cycling the device may fix the issue for a period of time, but it ends up back in the flashing state. Is there anything I can do myself?


There are a variety of reasons that can cause your sbRIO device to enter this 'unrecoverable state'. Before contacting National Instruments support, try the following steps:

  1. Try to power cycle the SOM if you have not already done so.
  2. Try to reset the device using the Reset button on your reference carrier board your SOM is attached to.
  3. If the device is able to establish connection with a host, try to format and reinstall software on the device outlined in: How Do I Format My Real-Time Target and Reinstall the Software?
  4. Sometimes improper power can be a cause of this issue. Using a multi-meter or other measurement device, verify the DC power to the device is a steady and continuous 3.3V. Also, verify all pins connecting your SOM to the carrier board are making full contact.
  5. Verify if the device is able to enter safe mode by following the procedure outlined in the user manual.
If none of the above troubleshooting steps work or the device is simply not able to leave this unknown state at all, please contact National Instruments technical support.
