Anyone know if an updated schematic is available for the MPU-6000EVB boards? The one in the user guide (dated 1/12/2011) doesn't appear to be the same as the board I have, with Sep. 28, 2011 printed on the silkscreen. The ref designators are off, and there are a few less components. The IMU isn't responding to SPI how we expect and it'd be nice to rule out schematic changes, etc.
