Find Out Firmware Version:

You can find Tone Board’s firmware version using the “Firmware Upgrade Tool for Windows 10”.


Note: After upgrading using the “EVAL drivers”, uninstall them and use your Windows 10 native USB-DAC driver, else you will hear a loud tone after sometime.

The update docs contains instruction to update via Mac. To confirm this is supported?



Well it works (most of the time), sometimes it doesn’t work via Mac, the XMOS updater is terrible. The worst error you’ll get is “unable to detect board”, which means you can’t brick your Tone Board using the Mac - but then you can’t update it either.

Updating via Ubuntu and Windows is more reliable, I just run a virtual machine of Ubuntu on the Mac, and connect the USB-DAC to it.
