The documentation for the eval 1 board states:
"The power supply system on this board is versatile. The kit can be powered in three ways: using a
MiniProg unit, DC wall adaptor, or a 9-V battery. The DC wall adaptor must be of 9 V to 12 V, 1-A
rating unit. The onboard voltage regulator converts input 9 V/12 V into 3.3 V/ 5 V"
I have a 9V, 1.5A dc wall adapter. I plug it into the board and no voltage is showing between vcc and gnd. Any idea why? Am I missing something?

See http://www.cypress.com/?app=forum&id=1573&rID=93246 for answer.
One other test not mentioned, check adapter output is good with a DVM.
