Zedboard LEDS on power up, board not booting

Question

Hi!

I left my Zedboard plugged in over night, switched of the supply and expected a fine, working device the next morning.

However, something must have happened over night - when i flick the power switch, the power-on LED does not light up, while all LEDs LED0 to LED7 are red.

The power supply itself seems to work fine and fuse F5 is intact - any ideas on what might have happened and how i can fix that?

Best

Hello Mike,

Could you try a different power supply/outlet. When the power good LED is not enumerated, the board prevents operation. If that doesn't help. Try measuring all your Power Rails on the board and report back the results. See Table 19 of the Zedboard Hardware User Guide http://zedboard.org/support/documentation/1521 for information on where the power rails are located and what they should be.
