FreeRTOS port for Mi-V Soft Processor

HW Platform and FPGA design:

This project is tested on following hardware platforms:

RISCV-Creative-Board

• RISC-V Creative board Mi-V Sample Design

PolarFire-Eval-Kit

• PolarFire Eval Kit RISC-V Sample Design

SmartFusion2-Advanced-Dev-Kit

• SmartFusion2 Advanced Development Kit RISC-V Sample Design

How to run the FreeRTOS RISC-V port:

To know how to use the SoftConsole workspace, please refer the Readme.md

The miv-rv32im-freertos-port-test is a self contained project. This project demonstrates the FreeRTOS running with Microsemi RISC-V processor. This project creates two tasks and runs them at regular intervals.

This example project requires USB-UART interface to be connected to a host PC. The host PC must connect to the serial port using a terminal emulator such as TeraTerm or PuTTY configured as follows:

    - 115200 baud
    - 8 data bits
    - 1 stop bit
    - no parity
    - no flow control

The ./hw_platform.h file contains the design related information that is required for this project. If you update the design, the hw_platform.h must be updated accordingly.

FreeRTOS Configurations

You must configure the FreeRTOS as per your applications need. Please read and modify FreeRTOSConfig.h. E.g. You must set configCPU_CLOCK_HZ parameter in FreeRTOSConfig.h according to the hardware platform design that you are using.

The RISC-V creative board design uses 66Mhz processor clock. The PolarFire Eval Kit design uses 50Mhz processor clock. The SmartFusion2 Adv. Development kit design uses 83Mhz processor clock.
