Hi Pietro,
Thanks for your updated information.
I have a question, if you don't run USB code, just run the helloword, whether the opensda COM can work on your side? J26 virtual port, can you find the com port in the win7, I also use the win7, it works Ok.
So, please try the opensda virtual com port at first.
Any updated information, please kindly let me know!
Have a great day,
Kerry
