[U-Boot] Not getting the Uboot prompt for sbc2410x using u-boot1.1.6

Hi All,

I am new to uBoot.

I am using the sbc2410x board. I successfully compiled the uboot-1.1.6 for this board. But after downloading the uboot.bin to the flash, i am not getting the uboot prompt on serial terminal.

I am using the NAND flash. Do i have to make the changes for NAND flash and recompile the uboot?
