## 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 | 450MHz
Flash | 16MB
RAM | 256MB
Vendor | Xilinx

## Configuration

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

    [env:e310-arty]
    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.

    [env:e310-arty]
    platform = sifive
    board = e310-arty

    ; change microcontroller
    board_build.mcu = fe310

    ; change MCU frequency
    board_build.f_cpu = 450000000L

## Uploading

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:

    [env:e310-arty]
    platform = sifive
    board = e310-arty

    upload_protocol = ftdi

## Debugging

PIO Unified Debugger - “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).

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