1V power rail burnt ...

Former Member
Former Member over 13 years ago

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

    Sometimes ESD will cause this sort of damage.

    Nothing can be seen, but there is a giant destroyed crater inside a device,,,perhaps 100 u in diameter.

    But what surprise me is that the board operated fine and it just stopped working while it was just sitting there, not being handled or anything.
