Intel Edison Arduino Barrel DC power jack - sketch after 2 minutes

Hi. I am developing an application that controls irrigation electrovalves. The problem is that the application stops after a few minutes running, sometimes lasts longer and another less.

I’m running the latest image 201606061707 and I am using the Arduino IDE 1.6.0. I have reviewed the code and I do not see the problem.

I have decided to make an example that turns on and off a led and test whether or not to end the application. If I powered intel edison by computer via a USB cable the sketch lasts longer than if I powered

intel edison by DC power jach (witch a power supply of 12vdc), and I do not understand why.

I found online that when using unsigned long variables I had to establish value using L.

Someone has had this problem that stops the sketch if powered the intel edison with barrel dc power jack?. I do not know if it's an error in the following sample code:

int led = 13;

unsigned long seconds = 1000L;

unsigned long minutes = seconds * 60;

unsigned long hours = minutes * 60;

// the setup routine runs once when you press reset:

void setup() {               

  // initialize the digital pin as an output.

  pinMode(led, OUTPUT);

  Serial.begin(9600);

}

// the loop routine runs over and over again forever:

void loop() {

  Serial.print("Wind");

  digitalWrite(led, HIGH);

delay(5 * seconds);            

  Serial.print("Pause");

  digitalWrite(led, LOW);   

delay(5 * seconds);

}

Thanks.
