Requirements

This step by step guide covers the tools and console commands for Windows users. The programs and tools this guide uses
are Linux based. Intels approach for making these Linux tools accessible to Windows users is the wrapper Cygwin, because of
that, the steps and console commands in a Linux environment are nearly identical.

All required Editors and tools are part of the Intel FPGA Design software packages.

Only the SD card build requires low level access to the SD card and can therefore only be performed in native Linux environment.

Software:

 - Intel® Quartus® Prime Lite - Version 18.1 build 625

 - Intel® SoC FPGA Embedded Development Suite (SoC EDS) - Version 18.1 build 625 - Extension of Quartus Prime lite

 - Linux Installation - As OS or as a Virtual Machine - Windows Subsystem for Linux is not suitable


Introduction

This guide has the objective to give users, with basic knowledge of computers, basic ideas of FPGAs and Software Design Tools,
a detailed Insight into the required steps to build and compile the necessary files to be able to boot the Hard Processor System
of a Cyclone V FPGA from a SD card. The HPS is chosen because it offers a limited amount of complexity and shows the basic
usage of many features from a FPGA Design.

The design process is separated along the usage of different programs and or tools. The output files and folders of one step are
essential for the next processing step. Each step in its own can offer complexity of varying degree on demand. This complexity can not be handled in a simple guide.

The usage of programs and tool will be described on point for the indented goal of booting the HPS.

Step 1 - Intel Quartus Project

 - Setup a project in Quartus Prime Lite (folder: project and project name: HPSexample)

 - Use the Plattform Designer to configure the resources needed to boot the HPS
    (System Memory and SD card access)

 - Connect the basic interfaces (Uart and i²c) of the HPS to the board resources

 - Compile the project to get the required files and folders for the next steps
    HPSexample.sopinfo / PlattformEditorHPS.qip file and (hps_isw_)handoff folder

Step 2 - Generation of the preloader and main bootloader from U-Boot sources

Use the handoff folder to generate the preloader and main bootloader
