3.1 Install dfu-util

The dfu-util suite of programs is used to talk to Toboot

Ubuntu and Debian

 sudo apt-get install dfu-util

Create /etc/udev/rules.d/10-tomu.rules and populate it with the following:

 ATTRS{idProduct}=="70b1", ATTRS{idVendor}=="1209", MODE="777"
 (Note: you can give it a more restrictive mode if you also give it a group that you’re in)

Windows

Download dfu-util-static.exe from the dfu-util repository and rename it to dfu-util.exe. Place it somewhere in your $PATH for convenience. To build examples, you’ll also want to get dfu-suffix.exe and put it in your $PATH.

Mac

Install Homebrew and run:

 brew install dfu-util
