1.6.3. Modify Project to Run from SDRAM Instead of On-Chip RAM

After completing the process of creating a simple "Hello World" application and downloading and debugging it in on-chip RAM of the Altera SoC, the next step is to configure the same project to run in SDRAM instead of on-chip RAM.

To use any SDRAM, the SDRAM controller needs to be configured. This is done by loading and running the Preloader.

For more information about loading and running the Preloader, refer to the "Preloader" section.
