Failed to load my program to run from SDRAM


I'm using DS-5 Eclipse for my project with the board ADC-SoC and following this guide ( to debug my program. It says that before running my program from SDRAM, I need to run a preloader to configure the SDRAM memory controller. However, after running the preloader from the example directory (the u-boot spl file), my debug command says that it fails to load my program to the address in the SDRAM. 

Does anyone know how to fix this issue ?? Does it have anything related to different boards (I'm using the ADC-SoC meanwhile the file is from the Cyclone V SoC Development Kit, both boards use Cyclone V SoC).
