Hi,
Since I don't know much neither about STM, nor electronics, I used others design to make this.
I need someone to check it thoroughly if possible, and to suggest changes, or to find errors.
I suppose that there isn't much to be changed there. This custom ST-Link V2.1 should use official firmware for ST-Link V2.0 programmer/debugger.
You'll find attached project in KiCad and description of it.
Best regards and thanks,
tpd
