SparkFun RED-V RedBoard

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

SparkFun

Configuration

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

[env:sparkfun_redboard_v]
platform = sifive
board = sparkfun_redboard_v

You can override default SparkFun RED-V RedBoard settings per build environment using board_*** option, where *** is a JSON object path from board manifest sparkfun_redboard_v.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:sparkfun_redboard_v]
platform = sifive
board = sparkfun_redboard_v

; 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).

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