Updating the firmware on Windows requires a driver installation and the use of a tool called DF-Util.

The driver (on Windows 10) is installed using a utility from http://zadig.akeo.ie/. Black Magic Probe uses a driver called libusbK, a selection offered by the Zadig tool.

In a command window then execute the following command:

	dfu-util.exe -d 1d50:6018,:6017 -E 20 -s 0x08002000:leave -D blackmagic.bin

Notes:
	1. BMP will enter DFU mode but may not have a driver installed. If that is the case install a driver for the update device using Zadig and run the above command again.
