Hello, I'm a beginner using the arduino IDE and I can't pass any code to my arduino's board, not even the examples. I've alredy tried change the computer, the cable, and for every code this message appears:
I had a similar problem with a chinese board, GBoard Pro.
It contains a MEGA2560, 16 MHz, but on board supplied with 3.3 V only.
Specifications demand minimum 4.8 V with a 16 MHz crystal.
The solution was to increase the on board supply voltage.
But to do so some actions on the board had been necessary.
