1 Introduction

This user guide is a walk-through of complete hardware and software flow to bring up SPI and GPO in a AFE79xx system along with a Xilinx FPGA. The hardware in this case refers to a Xilinx Microblaze processor based block design along with AXI SPI, AXI GPIO and other required peripherals.

The specific step-wise objectives are as follows:

  • Instantiate a block design with SPI IP in a Vivado project.
  • Map the required signals of block design to FPGA IOs.
  • Import hardware design and building a new Vitis application project for software development.
  • Compile, link, and download C program to processor along with bit file for FPGA.
