avrdude: stk500_getsync(): not in sync: resp=0x00
Solution 1
Probably you are using Bluetooth
. Solution is pretty simple. Just plug off TX
and RX
cable from Arduino and then upload your code. Then plug them in again.That worked great for me. For more listen this guy.
Solution 2
Try changing your board to Arduino UNO in "Tools" -> "Board" and also check the port =)
Solution 3
I changed Tools->Programmer->AVR ISP and it works now fine :)

avrdude: stk500_getsync(): not in sync: resp=0x00
I'm using arduino uno with ethernet shield.
I plugged a Led from digital pin to GND directly without any resistor if that was the problem, I do it often so far if that was the cause it just broke down now.
I already did the following:
• Port check
• Board check
• Driver check / re-install
• Cable check / renewed
none of it seems to work. If it is broken would my ethernet shield be harmed and be broken as well? Which should I replace.
