Tone 1: Upgrade to the Official Khadas Firmware (v2.00)

Upgrade your Tone1 to the v2.00 firmware for seamless compatibility with the Khadas Audio Dashboard and the new Tone Series DFU Tool.

Tone Series DFU Tool (only works with v2.00 firmware and higher)

Why does the Tone1 need the v2.00 firmware upgrade?:

Tone1’s latest software update includes a new USB Driver and DFU Tool (v4.86), and we’ve listed the most important changes below:

  • Seamless compatibility with the Khadas Audio Dashboard (Windows Tray Tool)

  • Tone Series DFU Tool can upgrade both Tone1 and Tone2 devices

  • Use both Tone1 and Tone2 simultaneously, without reinstalling drivers

  • Unique Khadas VID (Vendor-ID, Khadas is now a registered USB-IF Member)

  • Unique Khadas Manufacturer Name

In previous driver versions, you may have noticed that the USB-VID was the XMOS-VID, and the PID was for an XMOS evaluation product. Our new firmware helps to differentiate Khadas products from XMOS by including a unique VID and PID.

What is the Khadas Audio Dashboard?

The Khadas Audio Dashboard is a Windows Tray Tool included with the Tone2’s USB driver installation, and allows you to change a variety of settings related to the performance of your Tone1 or Tone2 DAC.

In addition, by updating your Tone1’s firmware to v2.00, you can use *both* your Tone1 and Tone2 simultaneously with Windows 7, 8.1 and 10 and the Khadas Audio Dashboard.

Please note that v1.0x firmware will not work with the Khadas Audio Dashboard (nor the Tone Series DFU Tool), and you will need to follow this guide to update your Tone1’s firmware.

When will the Tone2 be released?

By now you must be wondering…”Wait a minute, isn’t this driver upgrade also about the Tone2?” - and yes, you’re correct! When you install this latest driver package for your Tone1, it will also make the transition to Tone2 seamless, as the USB driver and DFU tool works for both devices!
