HiFive1

Hardware

Platform SiFive: SiFive brings the power of open source and software automation to the semiconductor industry, making it possible to develop new hardware faster and more affordably than ever before.

Microcontroller

FE310

Frequency

320MHz

Flash

16MB

RAM

16KB

Vendor

SiFive

Configuration

Please use hifive1 ID for board option in “platformio.ini” (Project Configuration File):

[env:hifive1]
platform = sifive
board = hifive1

You can override default HiFive1 settings per build environment using board_*** option, where *** is a JSON object path from board manifest hifive1.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:hifive1]
platform = sifive
board = hifive1

; change microcontroller
board_build.mcu = fe310

; change MCU frequency
board_build.f_cpu = 320000000L

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

HiFive1 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
