Having problem with booting panda!!!

Hi, I have checked out to the 2012.09.1 branch of the u-boot-linaro-stable source and built the u-boot for panda. It worked fine. Then I enabled the Debug prints and again built the u-boot. But this time the u-boot hanged up in the middle. In my observations, it hanged up at the end of the board_init_f() function in the arch/arm/lib/board.c. At the end it has the relocate_code() function that might cause the problem. Im stuck up with this and any help would be appreciated.

Thanks, Davidson. K
