Hi,
Within a few minutes of operation, the zedboard ceased to operate all together, no leds even come up anymore.
A bit of diagnostic shows that the 1V rails is no longer operating. Here's what it looks like : http://i.imgur.com/klrQhI6.png (so roughly 400 mv, and not stable). It's not really consuming any current (barely 10 ma).
Did anyone ever see such a failure ? And what could cause it ? I don't see any physical damage on the board, nor any obvious burnt component.
Cheers,
Sylvain
