[U-Boot] Uncompressing Linux Kernel hangs and no console messages

[Gurumurthy Gowdar]

Hi,
    Now image is downloading both linux kernel and ramdisk..but after
uncompressing the linux kerel ...it hangs there and no further console
messages....

no ttyS0 messages are printed....but when i see log_buf using BDI2000 by
giving md command ..console messages are displaying there....but unable to
get the console messages after booting linux kernel...so please help me out
in this regard to solve the above mentioned problem.

even i have put CONSOLE_SERIAL_TEXT_DEBUG....and serial boot command args
are added in menuconfig...when building the kernel image.

how to check whether serial console ttyS0 is getting activated or
not....please let me know the solution for this as early as possible.

thanks in adavnce
