Source Code of STLINK Upgrade

[j_filipe]

Greetings! I would like to know if there is an official source code, or an alternate source code (preferably in Java), or at least the USB DFU protocol.

The ST-LINK are not open source and open hardware tools, which is why no source code is available.

Information on the USB DFU protocol can be found in AN3156.

Hope that helps?
