There is a series of [[http://en.wikipedia.org/wiki/Light-emitting_diode|LED]]s on your board, near the center. 

They are labelled <kbd>VBB</kbd> ( red ), <kbd>3.3V</kbd> ( orange ), and <kbd>1</kbd> <kbd>2</kbd> <kbd>3</kbd> and <kbd>4</kbd> ( all green ).

We are still only interrested in the green LEDs.

Different behavior can represent different situations and problems for the board : 

<callout type="success" icon="true" title=" Normal pattern">

If your LEDs do this :

Then the firmware is running, and the LEDs are displaying correct behavior.

Click on **Normal pattern**

</callout>


<callout type="warning" icon="true" title=" SD card problem">

If your LEDs do this : 

{{http://chibidibidiwah.wdfiles.com/local--files/debug%3Aleds-are-on/leds-nosdcard.gif}}

Then the firmware is running, but the board encountered a problem reading or accessing the SD card, or the configuration file on the SD card. 

Click on **SD Card problem**

</callout>

<callout type="danger" icon="true" title=" Firmware crash">

If your LEDs do this :

Or this : 

{{http://chibidibidiwah.wdfiles.com/local--files/debug%3Aleds-are-on/leds-14.png}}

Then the firmware is not running.
