1. Configures the HPS pins I/O configuration shift register (IOCSR) and pin multiplexing
2. Configures the HPS phase-locked loops (PLLs) and clocking
3. Configures the external SDRAM
4. Loads the next image in the boot process, typically stored in a flash device such as the NAND flash
memory, Secure Digital/MultiMedia Card (SD/MMC) flash memory, or the quad serial peripheral
interface (QSPI) flash memory
5. Jumps to the next loaded boot image

Preloader Support Package Generator
The preloader support package generator provides you with an easy, safe, and reliable way to customize
the preloader.
The preloader image tool creates an Altera boot ROM compatible image of the preloader.
The preloader support package generator creates a customized preloader support package with preloader
generic source files and board-specific SoC FPGA files. The generator consolidates required hardware
settings and your inputs to create the preloader support package. The support package files include a
makefile to create the preloader image; you can download the preloader image to a flash device or FPGA
RAM.
The preloader support package generator allows you to perform the following tasks:
• Create a new preloader support package
• Report preloader support package settings
• Modify preloader support package settings
• Generate preloader support package files
