Programming and debugging
.. zephyr:board-supported-runners::
Applications for the HiFive1 board configuration can be built as usual (see
:ref:build_an_application) using the corresponding board name:
.. zephyr-app-commands:: :board: hifive1 :goals: build
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 behavior by adding the
-DOPENOCD=<path/to/riscv-openocd/bin/openocd> parameter when building:
.. zephyr-app-commands:: :board: hifive1 :goals: build :gen-args: -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
west flash
Depending on your OS you might have to run the flash command as superuser.
Refer to the detailed overview about :ref:application_debugging.
