SiFive HiFive1

|
|
Overview
|
|
********
|
|
|
|
The HiFive1 is an Arduino-compatible development board with
|
|
an FE310 RISC-V SoC.
|
|
More information can be found on
|
|
`SiFive's website <https://www.sifive.com/products/hifive1>`_.

|
Programming and debugging
|
|
*************************
|
|
|
|
Building
|
|
========
|
|
|
|
Applications for the ``HiFive1`` board configuration can be built as usual
|
|
(see :ref:`build_an_application`).
|
|
In order to build the application for ``HiFive1``, set the ``BOARD`` variable
|
|
to ``hifive1``.
|
|
|
|
.. code-block:: bash
|
|
|
|
export BOARD="hifive1"
|
|
|
|
Flashing
|
|
========
|
|
|
|
In order to upload the application to the device, you'll need OpenOCD with
|
|
RISC-V support. Download the tarball for your OS from the `SiFive website
|
|
<https://www.sifive.com/boards>`_ and extract it.
|
|
|
|
The Zephyr SDK uses a bundled version of OpenOCD by default. You can
|
|
overwrite that behaviour by adding the ``OPENOCD`` parameter to the
|
|
``cmake`` command:
|
|
|
|
.. code-block:: bash
|
|
|
|
# run from your build folder
|
|
cmake -GNinja -DBOARD=hifive1 -DOPENOCD=path/to/riscv-openocd/bin/openocd ..
|
|
|
|
|
|
When using a custom toolchain it should be enough to have the downloaded
|
|
version of the binary in your ``PATH``.
|
|
|
|
Now you can flash the application as usual (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details):
|
|
|
|
.. code-block:: console
|
|
|
|
ninja flash
|
|
|
|
Depending on your OS you might have to run the flash command as superuser.
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Refer to the detailed overview about :ref:`application_debugging`.
