libusb tool for flashing chinese ST-Link dongles. Please note that similarly to ST's updater, the uploaded firmware won't replace the bootloader (meaning that you should be able to reflash the original afterwards using ST's firmware update utility).

Usage: ./stlink-tool [options] firmware.bin Options:	-p	Probe the ST-Link adapter	-h	Show help 

stlink-tool has been tested under Linux and macOS. With sakana280's fork you can use it under Windows.

Required dependencies :

• C compiler (both clang and gcc seems to work great)
• libusb1
• git

git clone https://github.com/jeanthom/stlink-tool cd stlink-tool git submodule init git submodule update make 

ST's firmware upload protocol is USB's DFU protocol with some twists. Every DFU command is issued with the 0xF3 prefix, and the command set does not exactly match USB's.
