Updating VEXTREME

The following instructions show:

  • Installing dfu-util
  • Installing Zadig WinUSB Driver on Windows 10
  • Flashing VEXTREME

1. Install dfu-util on Windows 10

dfu-util is a command-line tool to flash devices that support DFU (Device Firmware Upgrade), such as STM32’s built-in USB bootloader.

Steps:

  1. Download the Windows build of dfu-util

  2. Extract the ZIP

    • Right-click the ZIP → Extract All… to a folder, e.g.:
      C:\utils\dfu-util\

  3. Add dfu-util to PATH (optional but recommended)

    • Press Windows Key + R, type: 
      rundll32 sysdm.cpl,EditEnvironmentVariables
    • Under System variables, select Path → Edit → New →
      C:\utils\dfu-util\
    • Click OK to close all dialogs.

  4. Verify installation

    • Open Command Prompt and run: 
      dfu-util --version
    • You should see the version printed.

2. Install Zadig USB Driver for STM32 DFU Mode

Windows may install an ST driver that doesn’t work with dfu-util.
We’ll replace it with the generic WinUSB driver using Zadig.

Steps:

  1. Download Zadig

  2. Put VEXTREME into DFU mode

    • Disconnect VEXTREME from your Vectrex and USB
    • Connect the JP1 jumper (short the pins of the JP1 connector together), connect the USB connection to the computer. At this point you can disconnect the jumper if you wish, the device will stay in DFU mode.
    • The device should appear as STM32 BOOTLOADER in Device Manager,
      usually under Universal Serial Bus devices or Other devices.

  3. Run Zadig as Administrator

    • Right-click zadig.exe → Run as administrator.

  4. Select the correct device

    • In Zadig, go to Options → List All Devices.
    • From the dropdown, select STM32 BOOTLOADER (USB ID 0483:DF11).
      • Confirm VID:PID is [0483:DF11].

  5. Install WinUSB driver

    • In the right column, choose WinUSB (v6.x.x.x) as the new driver.
    • Click Replace Driver (or Install Driver if none exists).
    • Wait until Zadig reports success.

3. Flash the update to VEXTREME

  1. Put VEXTREME in DFU mode

    • Open a command prompt by pressing WINDOWS_KEY + R and type CMD and press ENTER
    • Navigate to your Downloads folder, or wherever you have placed the VEXTREME binary.
    • VEXTREME should be disconnected from your Vectrex and USB
    • Connect the JP1 jumper (short the pins of the JP1 connector together), connect the USB connection to the computer. At this point you can disconnect the jumper if you wish, the device will stay in DFU mode.

  2. List DFU devices

    • Try to run dfu-util -l in the command prompt, you should see something like this.

      $ dfu-util -l

  3. Flash the upgrade

    • Use dfu-util to flash the binary with the following command via Terminal/Command Prompt:
      • NOTE: This is only for VEXTREME with the v0.3 jumper wire mod!
      • NOTE: Make sure you at least have SW v0.24 or v0.40 to start with
      • dfu-util -a 0 -d 0483:df11 -s 0x08000000:leave -D stm32-sw.v0.40.hw.v0.3-64kbankfix.bin

  4. Finishing up!

    • Once that completes, remove the JP1 jumper, and unplug/connect the USB again. You'll see the VEXTREME USB drive mount again.
    • Make sure you remove menu.bin since the Menu is built into the binary you just downloaded. Keeping an old menu.bin on a newer updated VEXTREME can break things.
    • Game on!
