Can't program Arduino Nano a second time [Solved]

Development Tools IDE 1.x
1

Hi,

I just got my new and shiny Arduino Nano and I started with a simple program using interrupts:

void setup()
{
  attachInterrupt(0, earLeft, FALLING);
  attachInterrupt(1, earRight, FALLING);
  
  Serial.begin(9600);
}

void loop()
{
  // empty
}

void earLeft()
{
  Serial.println("Left!");
}

void earRight()
{
  Serial.println("Right!");
}

And it works nice.

The thing is: I wanted to change it and upload a new version and I'm getting this error message:

avrdude done.  Thank you.

I can't upload anything anymore.

I've tried with Arduino v1.0.5 and Arduino 1.5.6-r2 BETA. I'm using MacOSX 10.9.2 (and I already tried rebooting the computer).

I can see in the serial monitor that my previous program is still running (despite all my attempts to overwrite it).

Any help is appreciated. Thanks.

Thanks, that solved my issue.

I have to push the reset button always when uploading the sketch, even though after uploading the BareMinimum example. Didn't have to the first time.

Also I found in the documentation for the micro that procedure: http://arduino.cc/en/Guide/ArduinoLeonardoMicro?from=Guide.ArduinoLeonardo#toc12 I think the documentation of the Nano should be updated to link to that page.
