I found out that I had connected the power supply ground to the pin 45 -
AGND, of the 70pin Pinto header. I disconnected pin 45 and connected pin 33
- GND to the power supply GND but, still, nothing happened. So I tried with
another Pinto board and the result is that only the green LED on the COM
lights up but still nothing else happens. During power up the red and blue
LEDs at the back side of the board are off.
1. Did I burn something when I connected the AGND pin of Pinto board to the
GND of the power supply? I noticed, using a multimeter, that at the first
Pinto board I used, the AGND and the GND pins are common. At the second
Pinto they are not!
2. The Overo FE still does not boot - just the green LED is on...

AGND may be connected to GND on the Overo but there is a likely a
ferrite bead or some filtering between the two. I doubt you fried
anything but GND, not AGND, is definitely the right place to connect.
