LED1 on SASEBO-W doesn't turn on
After taking a look at the SASEBO-W documents we find out that JP6 on the board is for FPGA Core Power and it must be Open to make this LED on.(The LED1 is specified with word Core on the board also.)

Note that this is not mentioned in the Quick Guide manual, but you can find it in table 21 of Side-channel Attack Standard EvaluationBoard SASEBO-W Specification here.
