Libero Projects

The Libero_Projects folder contains sample Mi-V Libero designs for Libero v2021.1. Libero projects for older Libero releases can be downloaded from their tags in this repository.

Design Features

The Libero designs include the following features:

• A soft RISC-V processor
• A RISC-V debug block allowing on-target debug using SoftConsole
• The operating frequency of the design is 50MHz
• Target memory is SRAM (32kB)
• User peripherals: 2 Timers, UART, 2 GPIO Inputs and 4 GPIO Outputs (GPIOs use fixed configs for simplicity and better resource utilization)

Target Hardware

Details of the PolarFire Evaluation Kit and it's features can be found:

• MPF300-EVAL-KIT (MPF300TS)
• MPF300-EVAL-KIT-ES (MPF300TS_ES)

FlashPro Express

The FlashPro_Express_Projects folder contains the pre-generated programming files, which can be downloaded directly to the target board using FlashPro Express.

Design Tools

The following design tools are required.

Libero SoC v2021.1

Libero SoC is Microchip's FPGA design software.

FlashPro Express

FlashPro Express is Microchip's Programming and debug tool. It is included in the Libero SoC software and is also available as a standalone application. Please note, that if Libero SoC is already on your system, you do not need the standalone version.

SoftConsole

SoftConsole is Microchip’s free software development environment facilitating the rapid development of bare-metal and RTOS based C/C++ software for Microchip CPU and SoC based FPGAs. It provides development and debug support for all Microchip SoC FPGAs and 32-bit soft IP CPUs. SoftConsole can be downloaded.
