Issue in booting the beagle board...

Hi..

The following is the issue we are facing while trying to boot the
beagle board.
during the first time powerup of the board without sdcard we could see
the boot messages in the terminal.While trying to boot from the SDcard
the board got hung at the message "reading boot sector".Resetting the
board did not help.Now even without SDcard i am not able to get the
boot messages in the terminal.At times it displays junk messages if
the RS232 cable is not inserted in the right manner.The setting for
serial port is followed as given in the website.Kindly help us solving
the issue.
