Transfer of uImage from TFTP server fails with the RAM address mentioned in SPI flashing procedure.

I use the following link to set up kernel booting from SPI flash :

http://processors.wiki.ti.com/index.php/Booting_Linux_kernel_using_U-Boot

However, I am stuck at the point :

U-Boot> tftp 0xc0700000 uImage

Following is the screen shot of TeraTerm window :

BARCO_UBOOT#tftp 0xc0700000 uImage
link up on port 0, speed 1000, full duplex
Using cpsw device
TFTP from server 10.64.16.174; our IP address is 10.64.16.63
Filename 'uImage'.
Load address: 0xc0700000
Loading: #

Last, but not the least, I need to know the exact value of offsets for flashing uImage & filesystem to the flash (Winbond 4096 KiB W25X32 SPI chip) used in DM8148 EVM(Mistral).
