Problem while booting the BBGW board with Debian image

Hello,

I tried to Boot the BBGW board with new debian image.I follow all the steps given in https://beagleboard.org/Support/BoneScript/updates/ .After inserting the SD card I pressed the user or boot button on the board and power up the board. I pressed the button for around 1 hour but not a single LED was glowing.
Please help me to boot the board.

Thanks,
Aditya
