Hi,
I'm working on galileo gen2 board.
attachInterrupt() does not work.
please help me!

Here is my code. i am using sketch.

--------------------------------------------------------------------
int led = 13;
int inputPin = 2;
boolean value = LOW;

void setup() {
  pinMode(inputPin, INPUT_PULLUP);
  pinMode(led, OUTPUT); 
  attachInterrupt(0, intHandler, CHANGE);
}

void loop() {
}

void intHandler() {
  digitalWrite(led, value);
  value = !value;
}
