Try the following thing:
Copy the .elf file to the folder where elf2img.exe is present.
Open a command prompt (Start --> Run --> cmd). Go to the elf2img folder (in my case: C:\Cypress\FX3 SDK\util\elf2img) in the command prompt. Then give the following command:
elf2img.exe -i USBBulkLoopAutoEnum.elf -o USBBulkLoopAutoEnum.img 0x0C 0xB0 -vectorload yes
Here I am assuming the name of the .elf file as USBBulkLoopAutoEnum.elf. In your case it might be a different one.
After running the above mentioned command it will output a .img file. Use that .img file to program the EEPROM.
