2 Overview
The HiFive Unleashed Platform™ is purpose-built to emulate most of the functionality of the upcoming
PolarFire SoC FPGA, which will be the industry’s first RISC-V based FPGA SoC.
This guide describes the MPFS-DEV-KIT, board setup, and installation steps to get the HiFive Unleashed
platform boot Linux. New IP cores can be ported on the PolarFire FPGA with the Libero SoC PolarFire
Design Suite. For more details on the design suite, see section .FPGA Design in Libero (see page 17)
2.1 HiFive Unleashed Platform (MPFS-DEV-KIT)
The HiFive Unleashed Platform consists of the SiFive’s HiFive Unleashed kit and Microsemi’s HiFive
Unleashed Expansion kit with their respective accessories. Microsemi's HiFive Unleashed Expansion
board enables users to create a Linux system running on a RISC-V core complex, with a large FPGA fabric
accessible through the memory map. The expansion board is shipped with a pre-configured bitstream
enabling PCIe root port functionality.
