Hi to everybody, finally I've done it! I've tried with a third cable (a very short and low budget one)
The other two cables (apparently high quality and 50cm long) won't work. The third (robbed to my son's low quality bluetooth speaker charger) worked like a charme.
Anyone can tell me why? I'm interested to understand in depth.
There is a kind of cable suitable for the connection to the Portenta boards?
Thanks,
Andrea
