I bought a BBB and tested it: at start up, the USERS leds blinks. I have followed the instructions in the site Beagleboard:Updating The Software - eLinux.org.
I unplagged the power supply and I keep pressed the S2 button (boot) (at least 1 minute), I Applied the power to the board by plugging in the cable (external power supply 5 V, 3 A). Only power led is on.
When I pressed the power button for at least 8 seconds, the power led is turned off then after 3-4 seconds it is turned on.
Could you please help me?
