1V Power Rail Question

I was looking at the 1.0V power section on the microzed (U17 and surrounding parts).

When the microzeds are in the Breakout Carrier and powered up, I am only seeing 0.2 Volts across C57. This is true for all my microzeds.

Shouldn't this supply be 1 Volt?

Cheers,
David

-EDIT-
1 of my 4 microzeds does in fact show 1.0V for this node.

Any ideas why the others do not?

Hi David,
I echo Bryan's comments above. An unconfigured MicroZed should NOT draw 3A on the core. If that is your "good" board, you should RMA that one as well. Bryan and I are talking about this issue as we speak. I'll follow up with you directly shortly.
Thanks
Chris

I've re-designed my power distribution and power sequencing, things look much better now.

I believe that my reliability issues have been self-inflicted!

Thanks for the help. I won't use the RMAs.

Cheers,
David
