TM4C1294NCPDT: Loading Program

I do the same steps but the led did not blink at all

Did you reset the board after you load the image?

What does it say on the Uniflash Console window when you program? Does it say it passes or fails?

You can either use Uniflash or CCS to view the memory content of the flash. Do you see the blinky code starting at 0x0? Why don't you single step the code as it toggles the LED. If you don't see LED blinking you might want to check if LED is somehow damaged. There are four user LEDs on the board. Modify the code to blink other LEDs to rule out if any board level issue. If you have another LaunchPad, try it and does it show the same problem?

when i use CCS the led is blinking and when i use the UNIFLASH or LM Flasher the blink did not blink, i open the memory content at UNIFLASH i found the code resides in memory but it still not working or blinking i don't know why ?

Wow! when i load .out file in UNIFLASH it runs and the led is blinking now 
why ..bin does not work do you have any idea ?

and wheb i check the binary check box in UNIFLASH it does not run !! but when i uncheck using .out it runs 

Uniflash can load .bin file just fine. Why don't you write out the flash content after you load using CCS and Uniflash. Compare the two files. Are they not the same?

Note : I use another code other than blinky.out because when i tried blinky it still does not work 

I showed you how to save the memory content and compare the two files. 

they are the same 

That is very weird. I have not seen a problem like this. Do you have another board to try? You have not answered me if you reset the board after programming.

After you load the .bin using Uniflash, you can connect to the board using CCS and do a load symbols. Use blinky.out to provide the symbols. The load symbols merely add the symbol for debugging purpose. It will not overwrite the code. Once you have the symbols, you can single step the program as if you loaded blink.out using Load Program. You can place breakpoints and do you see the pin is getting toggled in the code.
