stlink-tool
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).
Compiling
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
Writing firmwares for ST-Link dongles
Firmware upload protocol
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.
