                This is a basic guide for building a program on the DE10 Nano SoC. This walks through using Quartus Prime, Qsys, and EDS from start to finish. The program counts up four LEDs on the HPS
              
          
        
      
        
  
      
    I successfully created a project instantiating the HPS in Qsys. I added a parallel I/O in Qsys to allow the HPS to communicate with the LEDs via the HPS-to-FPGA lightweight bus. From there, I generated a preloader and U-boot along with the SOF file. I also wrote a simple C program that counts from 0-15 and sets the LEDs to that value every second. This encompasses about every step required to be able to communicate between the FPGA and HPS, so this is definitely a first step. I'm going to document what I did and how you guys can get this running.
I did this on Windows since that is my primary OS. Things are different on Linux, so you will have to figure them out if you try to do this on Linux.
File Structure

DE10NanoUART-FPGA

Project containing everything necessary to get exactly what I have running
HPS_FPGA_LED - Source code and makefile for the C program to blink LEDs
hps_isw_handoff - ISW stands for Initial SoftWare so it is the first thing to be ran AFTER the hardcoded bootrom is loa
