LEDs not blinking on BBB

hai …

I am working on BBB. I want to port opewrt on BBB. In order to boot from SD card i removed the MLO in the fat partision of eMMC. I put the SD card in micro SD card slot . I powered the Board and i pressed the button bove thye slot but leds are off and not booting from SD card. I remove the SD card and apply the power then also the four user leds are off ,

I tried with the BBB-flasher-2013.09.tar.xz but there is no booting process , all the leds are off,

Press the button and hold it, then power on the board and see if that works. Otherwise the SD card may not be configured correctly…
