【FAQ】搭配RFS使用Azure solution如何通过HPS访问FPGA端2x20 GPIO

Doreen

使用DE10-Nano-Cloud-Native_18.04.img
基於 Module5_Sample_HW 修改，增加32 bits PIO接到GPIO 1

將RFS接到GPIO_1，使用RFS上的BT_KEY做範例
依照de10-nano手册Chapter 7 Examples for using both HPS SoC and FGPA 加入PIO控制
PIO的manual: https://www.intel.com/content/ww ... /21-4/pio-core.html

software: software/main.c
overlay: output_files/Module5_Sample_HW.rbf, rfs-overlay.dtbo, overlay.sh

    Flash SD Card with Ubuntu 18 Image

    connect RFS to GPIO_1 of DE10-Nano
    Disable overlay and lightdm during boot
    Copy the overlay file to to /home/root/
    Copy the software(HPS_FPGA_KEY_LED) to to /home/root/
    Execute overlay.sh in DE10-Nano
    ExecuteHPS_FPGA_KEY_LED in DE10-Nano, press BT_KEY of RFS
