The O-Link can be used as:
1) USB to RS232 adapter,
2) USB-JTAG adapter, and
3) On-Chip debugger.
4) Nand & Nor Flash programmer
The O-link by now is the fastest and most convenient debugging&downloading tool for the Samsung S3C24x0 microcontrollers.

For example, to download the uboot to the Nor Flash on the MINI2440, you just need to:
1) Connect the MINI2440 to the PC via the O-Link debugger
2) Run the Windows CMD tool and enter the folder in which the uboot resides
3) Run the command "sjfusb uboot.bin"
4) Enter the number "2" to select the CPU type
5) Enter "1" to select the Nor Flash as the target:
6 ) Enter the target offset "0" and the flashing will begin:
A few seconds later you will see the uboot running in the Nor FlashProduct Specification
