Nice finding! Well, this would mean that we have to clone the ST-link device (where I have not yet an idea what is inside) and add another USB socket. But there seem to be clones: https://www.gearbest.com/development-boards/pp_62989.html?currency=EUR&vip=2275155&gclid=CjwKCAiAoqXQBRA8EiwAIIOWstP9pf8EWlN1SaHyGVUZzDDjkmMVt329W6Misb_BTv_HxOqSr28UMxoCQ_8QAvD_BwE Hm. Well, the ST-Link device is another Microcontroller with built-in firmware. So how do we flash that :) BR, Nikolaus _______________________________________________ Community mailing list Community@tinkerphones.org http://lists.goldelico.com/mailman/listinfo.cgi/community http://www.tinkerphones.org
