BeagleBoard XM Rev C Booting Problem

Hi All,
     I purchased the BeagleBoard XM Rev C and Tested it and it was
booting properly. I connected the serial port to board and i was able
to see the output in hyper terminal. and once i formated the sd card
using the script ( Makecard.txt ) given in
this site. and i directly burnt the image provided in site
( i.e xMc_4_25.img ) and now my sd contains all the images like 1)
MLO, 2) U-BOOT.BIN 3) uEnv.txt 4) UIMAGE in boot partition and file
system in another partition. and when i inserted the sd card in BB
LEDs started blinking Continously but i was not able to see the
messages in my terminal even after waited for 15 Min or so. So please
help me in this issue.

My serial port settings are

port -- ttyS0, 115200 8N1
Hardware flow control -- No
Software flow control -- No

and uEnv.txt contains


dvimode="hd720 omapfb.vram=0:8M,1:4M,2:4M"



console="tty0 console=ttyS2,115200n8"


make it console=ttyO2,115200n8"
this may help
