How run a program without CCS

Hello

I am using LCDK6748 board.

I have an example of blink LED.

When I use CCS to program, debug and run, it works.

Now I want to run the example without using CCS.

I use sfh_OMAP-L138.exe to erase the NAND and load the example.

At the end of the process, the screen shows "Operation completed sucessfully". But the the program does not work.

How can I run the program??

Thank you

Kind Regards
