Arty FPGA Dev Kit


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 450MHz
Flash 16MB
Vendor Xilinx


Please use e310-arty ID for board option in “platformio.ini” (Project Configuration File):

platform = sifive
board = e310-arty

You can override default Arty FPGA Dev Kit settings per build environment using board_*** option, where *** is a JSON object path from board manifest e310-arty.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = sifive
board = e310-arty

; change microcontroller
board_build.mcu = fe310

; change MCU frequency
board_build.f_cpu = 450000000L


Arty FPGA Dev Kit supports the next uploading protocols:

  • ftdi
  • jlink
  • minimodule
  • olimex-arm-usb-ocd
  • olimex-arm-usb-ocd-h
  • olimex-arm-usb-tiny-h
  • olimex-jtag-tiny
  • tumpa

Default protocol is ftdi

You can change upload protocol using upload_protocol option:

platform = sifive
board = e310-arty

upload_protocol = ftdi


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


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).

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