Altera SoC Embedded Design Suite User Manual

The Preloader is an essential tool for SoC software. It performs the low-level initialization, brings up
SDRAM memory, loads the next boot stage from flash to SDRAM and executes it.
The Preloader is already delivered as part of the GHRD in the
hardware/cv_soc_devkit_ghrd/software/preloader
folder.
In this example, you will re-create the Preloader in the folder
hardware/cv_soc_devkit_ghrd/software/spl_bsp
.
The screen snapshots presented in this section were created using the Windows version of SoC EDS, but
the example can be run in a very similar way on a Linux host PC.
The steps to create the Preloader are:
1. Start an Embedded Command Shell by executing
Shell.bat.
2. Run the command,
bsp-editor
. The BSP Editor dialog box appears.
Note: The tool that generates a preloader support package is the BSP Editor, also used to generate
BSPs for other Altera products.
3. Select
File > New BSP
.The New BSP dialog opens.
4. Click the
“…”
button to browse for the Preloader settings directory in the New BSP dialog box.
5. Browse
for the
hardware handoff folder. The rest of the Preloader settings are populated automatically.

6. Click OK to close the New BSP dialog box. This will populate the BSP Editor dialog box with the
default settings.
