The firmware on a zForce AIR sensor can be updated easily using the Neonode zForce AIR Sensor Firmware Update application for Windows. Download it here: https://support.neonode.com/docs/display/Downloads/Firmware+Update+Software.

Prerequisites

Hardware requirements

  • CPU: 1 GHz
  • RAM: 512 MB
  • Disk space: 20 MB
  • Internet connection (for the automatic download of necessary Windows drivers)
  • The interface board provided with the evaluation kit.

Operating System requirements

  • Windows 10
  • Windows 8.1

Software requirements

  • .NET Framework 4.5 or higher is required and can be downloaded from Microsoft's official website. Windows 8 and higher has this installed by default.

Procedure

  1. Download and run the application, https://support.neonode.com/docs/display/Downloads/Firmware+Update+Software.
    The new firmware version is displayed, under Firmware
  2. Connect the zForce AIR sensor to the computer via the provided interface board. Refer to Getting started with zForce AIR Touch Sensor Evaluation for details on how to connect the sensor.
    The connected sensor's current firmware version is displayed, under Device.
  3. Make sure the checkbox for the sensor is checked and click Update.
    The new firmware will be loaded into the sensor. If it is the first time the application is used to update the firmware, an internet connection will be required to install necessary drivers. 
    A progress bar will be displayed with status during the firmware update. This process may take a few seconds to a minute depending on the computer.               
    When the firmware update is completed, a pop up message is displayed. The sensor can be used right away after the update is finished.                  

Troubleshooting

If the updating fails or the device does not show up in the application, check the following possible scenarios. If the problem persists, please contact support.

The sensor does not appear under Device in the application after it is plugged in

  1. Click Help... and follow the instructions.

The progress bar gets stuck at 0% to 5% during the firmware update

  1. Click Help... and follow the instructions to set the sensor in DFU mode.
  2. Check "STM device in DFU mode" or "STM32 BOOTLOADER" device under "Universal Serial Bus controller" or "Other devices" in Windows Device Manager to ensure drivers are working properly. Uninstall or update the driver if necessary.

The firmware update fails with the message "Failed to download new firmware" or the progress bar gets stuck at about 50 to 60%

  1. Click Help... and follow the instructions.

The progress bar gets stuck at 100%  during firmware update with the message "Waiting for USB configuration...",

This is because the sensor failed to leave "boot mode" but the firmware is already updated.

  1. Click on Cancel button and re-plug the sensor. The new firmware is updated and the sensor is ready to be used.
