why is ALL of my streaming data zero'd? (Cyton-clone pcb)

My board is layed out from scratch but based on the exact same schematic as the Cyton board (and closely matches the layout)

I've got a successful stream back into the OpenBCI GUI and it is all zeros, including temp, accelerometer data, everything.  The data saved to a file also shows all zeros.  This is a head-scratcher.  I can't think of a point in the acquisition stream that would account for ALL data, although I'm no expert yet.
thanks

    How do I erase or comment 'solved' when I am replying to my own post?
    Anyway, this question is moot.  I got the accel IC footprint mirrored, blegh!  I'm surprised I was able to get any data from anything!  I just removed the IC and I'm getting non-zero data, yay!  (board re-layout, nay!)
