Junk characters in Putty terminal on Angtsrom 2009 MMC boot

Hello All,
I have a Beagle Board XM, rev C along have latest Angstrom running on it. I want to switch to Angstrom 2009 stable image for some reasons. I did setup MMC with Angstrom 2009. When I try to Boot up this card, this gives junk characters on Putty terminal window. But MMC comes with Board working fine. I don’t know whats the problem. Did anybody have such problem ?? Please share your ideas.

Thanks,
Dhut
