provided for Windows, so you can download and use it.

You can nd dfu-util in the standard package repository.
sudo apt-get install dfu-util
dfu-util --version
Boot the device in DFU mode. Use one of the following methods to enter DFU mode.
Turn on the power by jumpering the BOOT pin on the PCB. (After turning on the power, remove the jumper.) The screen

Execute the following command. build/ch.bin describes the path to the .bin of the downloaded rmware le.
