Firmware Upgrade

Prerequisites

The usbmuxctl tool uses dfu-util to upgrade a devices firmware. On distributions based on Debian this is available as the dfu-util package.

Warning

Firmware updates are not available on Windows!

How to check for Firmware Updates

Firmware updates for the USB-Mux come packaged with the usbmuxctl python package. Make sure to update the usbmuxctl package from time to time.

If a firmware update is available a message is displayed in usbmuxctl status and usbmuxctl list:

$ sudo usbmuxctl list
Serial      | USB-Path           | Host-DUT Lock? | Connections
----------- | ------------------ | -------------- | -----------
22          | 1-3.1              | unlocked       | None         Software update for USB-Mux available

Install an Update

Updates can be installed using the usbmuxctl update command.

Note

This commands must be called with a --serial <serno> parameter even if only one USB-Mux is connected to the host.

The command will install the currently packaged firmware onto the specified device:

usbmuxctl --serial 00022 update
dfu-util 0.9
