System Recovery: Flashing the SD Card

Operating anomalies or improper shutdowns can sometimes corrupt the system instructions stored on the Neon's internal SD card. If the controller's status LEDs indicate a communication failure, you will need to reflash the firmware image.

Pre-Diagnostic Checklist

Before proceeding with a system reflash, ensure you have ruled out secondary connectivity issues by reviewing these technical guides:

  • Hardware Status: Analyzing Controller Board Activity (LED patterns).
  • Interface Issues: Troubleshooting Ethernet and Wi-Fi Connections.

Support Tip

The flashing process overwrites system data. If you have custom network configurations stored on the card, they may need to be reconfigured after the recovery.

1. Preparing the Imaging Software

To write the firmware image to the SD card, we recommend using BalenaEtcher, as it verifies the data integrity after flashing.

  1. Download: Obtain the BalenaEtcher installer from the official source.
  2. Installation: Run the executable and follow the setup wizard.
  3. Initialization: Open the application once the installation is complete.

2. Acquiring the Neon Firmware Image

  1. Download the Image: Download the latest Neon Firmware Image (.zip or .img).
  2. Extraction: Right-click the downloaded file and select "Extract" to a dedicated folder. Ensure you have the raw .img file ready for the flashing process.

3. Hardware Access and SD Removal

You will need the Allen key and the SD adapter provided in your Neon Technical Kit.

  1. Power Down: Completely disconnect the Neon from the power source.
  2. Access the Controller: Open the lateral electronics bay.
  3. Eject the Card: Locate the micro-SD slot on the mainboard and gently remove the card.
  4. PC Connection: Insert the micro-SD into the USB adapter and connect it to your computer.

4. The Flashing Procedure

Critical Warning: Drive Selection

Verify the target drive carefully. Flashing the wrong drive (like your PC's Hard Drive) will result in permanent data loss. The Neon SD card typically shows a capacity of 8GB or 16GB.

  1. Select Image: In BalenaEtcher, click "Flash from file" and select the extracted Neon .img file.
  2. Select Target: Choose the SD card reader as the destination drive.
  3. Execute: Click "Flash!" to begin the process.
  4. Validation: Wait for the software to finish the "Validating" stage to ensure the firmware was written without errors.

5. System Reinstallation

  1. Reinsert the Card: With the Neon still powered off, insert the SD card back into the mainboard slot. Ensure the gold contacts are facing the board.
  2. Status Verification: Power on the machine before closing the side panel. Check the Yellow LED; it should be pulsing, indicating active communication.
  3. Connectivity Test: Open Due Studio and attempt to establish a link.

Recovery Complete

If the status LED is pulsing and the software connects, your Neon system is restored. You can now close the electronics bay and resume your projects.

Still Offline? If the yellow LED remains solid or off after a successful flash, there may be a hardware fault with the SD card itself or the slot. Contact Due Laser Support for a replacement component.
