I have loaded the u-boot.elf binary to RAM over UART using the OST
utility on Windows XP. I tried to load u-boot.bin to RAM but it is not
working, I think OST is expecting windows binaries when the extension
is .bin. The ELF binary which is compiled on Linux gets for omap730p2
sample board gets successfully downloaded to RAM at the specified
address. I have configured the UART as mentioned in the manual by
using Hyperterminal/Terra Term. After downloading the ELF binary to
RAM, I should
be seeing the U-boot prompt on console. But, just a cursor blinks on
screen. I am sure the  connection is being established but no prompt
is seen.

1. Do I need to burn u-boot.bin and not u-boot.elf? I converted .elf
binary to .raw using OST and it was downloaded successfully to RAM.

2. If downloading to RAM is correct then what might have gone wrong ? Why the
u-boot prompt is not visible? What I am missing?CONFIG_SKIP_RELOCATE_UBOOT

3. I have taken care that U-Boot doesnt relocate itself to RAM by

PS: I know I should be using JTAG. What could be the problem with this
console stuff.
