James,
Thanks for your reply.  I have connected battery input with an Agilent DC power supply.  I set it to 5v with current setting of 2A.  During the boot up, the LCD actually lights up before the board going into reset again.  I have noticed the current draw is about 0.4amp with LCD.  without LCD the current draw is about 0.2amp.

Thanks again,

What power supply are you using. Does it provide at least 1amp. Also
is it providing a full 5 volts.
