Kathir,

There are several ways to accomplish this.  If your board has a working
u-boot flashed in it, then you can do it from the u-boot prompts via
kermit, or tftp.

If you don't have u-boot working yet, then I recommend the u-boot.out
file that comes on the CD.  If you load it and run it, it should flash
u-boot into the system.  Then you can use the kermit/tftp from u-boot to
flash your own bootloader.  Another approach is the USB bootloader,
which will reflash a new u-boot into your board.

I strongly recommend you look at the OSK5912 newbie guide.  Search for
this:  "osk5912 newbie guide" on the web and you get an excellent
document that should help you accomplish what you need.

Actually, if you have CCS and a JTAG emulator, then instead of using the
u-boot.out file that comes with the CD, you can just use CCS to download
the "u-boot" file that gets built when build u-boot. CCS has the ability
to load COFF and ELF formated files. The u-boot builds 3 files, namely
u-boot.srec, u-boot.bin and u-boot. The last file is an ELF file. 

So to summarise:

1). Load the u-boot file with CCS and run it 
2). Use u-boot to download the u-boot.bin with tftp or kermit 
3). Use u-boot to program the u-boot.bin into flash. 

Cheers
