Buongiorno signori
Ultimamente sto avendo questo scherzo.
in fase di caricamento dello sketch , riesce a leggere dalla scheda e poi nel momento in cui deve scrivere mi segnala timeout.
ho provato a caricare uno sketch vuoto e me lo carica normalmente.
qui di seguito riporto i valori di debug .
sono costretto a togliere il collegamento alla seriale altrimenti cicla continuamente.
Qualcuno puo' dirmi cosa succede?
Vi ringrazio tanto.
