My Kernel hangs after images verification and no boot msgs on Console?

[dnl]

Hi Andy,

I am using MPC8555CDS board, montavista kernel, and  uboot for board bringup...
when i am booting montavista kernel using uboot i didn't get any message on Console...

 1. i can view the booting messages by "Dumping the printk Log Buffer". 
 2. i am passing the "bootargs=console=ttyS0,115200 root=/dev/ram0 rw"

How can i get boot messages on serial console?

Regards,
Saravanan.S
