[Gumstix-users] the GPIO interrupt of gumstix OMAP3530 border

[<vig...@si...>]

dear gumstix:
      hello!I am a user of your product OMAP3530 gumstix boardr.
      I have some question about the boardr,yesterday, I want to develop the extern interrupt with the GPIO_65 pin.When I connect the pin with a VCC(5V) the boadr could'nt work anylong.
      When I restart the board,the board print little information,and can't run the u-boot.
      So I want to know if my board is broken,where is wrong?
      can the GPIO pin bear a 3.3V voltage when it can only output 1.8V?
      Thank you for your explain!
