Note: Banks 34 and 35 are powered from an adjustable voltage rail. Jumper, J18, selects this

voltage. Selectable voltages include 1.8V, 2.5V and 3.3V. The 3.3V jumper was intentionally

unpopulated on ZedBoard as these banks primarily connect to the FMC interface and many FMC

cards are only 1.8V and 2.5V compatible. Connecting 3.3V to these cards can damage them, so

leaving this jumper unpopulated reduces the risk of damaging FMC cards.
