MKR1000 Doesn't Run "Blink" Sketch

I bought and MKR1000 and installed all the drivers on my computer. I am running Linux on a Chromebook, and I have the Arduino IDE 1.6.12.

When I upload the sketch to the board, I get this response (below) but the code itself doesn’t appear to run. The LED does not blink.

I would appreciate any help anyone has to offer. Thanks.

I can only presume your sketch does something with an LED ?
Include it if you don't mind ?

The console says it sent up to the MKR just fine so maybe a code issue.

Here's the code, copied from:

  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO 
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN takes care 
  of use the correct LED pin whatever is the board used.
  If you want to know what pin the on-board LED is connected to on your Arduino model, check
  the Technical Specs of your board  at
  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
