SparkFun RED-V Things Plus
##########################
Overview
********
The SparkFun RED-V Things Plus is a development board with
a SiFive FE310-G002 RISC-V SoC.

- `SiFive FE310-G002 User Manual`_
Programming and debugging
*************************
Building
========
Applications for the ``sparkfun_red_v_things_plus`` board configuration can be built as usual
(see :ref:`build_an_application`) using the corresponding board name:
.. zephyr-app-commands::
:board: sparkfun_red_v_things_plus
:goals: build
Flashing
========
The SparkFun RED-V Things Plus uses Segger J-Link OB for flashing and debugging.
To flash and debug the board, you'll need to install the
`Segger J-Link Software and Documentation Pack
<https://www.segger.com/downloads/jlink#J-LinkSoftwareAndDocumentationPack>`_
and choose version V6.46a or later (Downloads for Windows, Linux, and macOS are
available).
With the Segger J-Link Software installed, you can flash the application as usual
(see :ref:`build_an_application` and :ref:`application_run` for more details):
.. zephyr-app-commands::
:board: sparkfun_red_v_things_plus
:goals: flash
Debugging
=========
Refer to the detailed overview about :ref:`application_debugging`.
