I'm working with an Arduino MEGA 2560 board programmed by Xloader software and I would like to have some informations or suggestions about the following problems:
- First, I've found out that some boards produce a beep after programming them and some others don't; do you know why?
- Second, sometimes the boards that produce a beep, after a short time, started beeping continuosly until the serial port is connected. Do you know why? Is it a problem about a software failure?
