Upload Error

Development Tools IDE 1.x

Hey, I need some help about upload.
I've got a french version:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x6e
avrdude: stk500_recv(): programmer is not responding

Problème de téléversement vers la carte. Voir http://www.arduino.cc/en/Guide/Troubleshooting#upload pour suggestions.

My code:

void setup() {
  pinMode(13,OUTPUT);
}

void loop() {
  
  digitalWrite(13,HIGH);
  delay(1000);
  digitalWrite(13,LOW);
  delay(1000);
}

This is a really simple code (is just for testing)

I'm on Windows 7 and I use Arduino Genuino Uno.

I don't know how I can resolve this problem.

Which version of the IDE? Have you tried the loop back test.

Do you have the right board selected?

0x6e as the response every time suggests (not conclusively though) incorrect board selected. That means it's getting a response, and it's the same thing every time, but it's wrong, presumably because the serial port is running at the wrong baud rate, or the protocol is entirely wrong.

If it's a Pro Mini or Nano, try telling the IDE it's an Uno. For good measure, try all the 328P-based boards - Pro Mini, Uno, Nano, Duemillanove. Though if your board is an official Uno, this would be a bizarre finding. Among chinese clones, this kind of thing is common.
