Building

Applications for the hifive_unleashed board configuration can be built as usual (see :ref:build_an_application) using the corresponding board name:

.. tabs::

.. group-tab:: E51

  .. zephyr-app-commands::
     :zephyr-app: samples/hello_world
     :board: hifive_unleashed/fu540/e51
     :goals: build

.. group-tab:: U54

  .. zephyr-app-commands::
     :zephyr-app: samples/hello_world
     :board: hifive_unleashed/fu540/u54
     :goals: build

Flashing

Current version has not yet supported flashing binary to onboard Flash ROM.

This board has USB-JTAG interface and this can be used with OpenOCD. Load applications on DDR and run as follows:

.. code-block:: console

openocd -c 'bindto 0.0.0.0'
-f boards/riscv/hifive_unleashed/support/openocd_hifive_unleashed.cfg riscv64-zephyr-elf-gdb build/zephyr/zephyr.elf (gdb) target remote :3333 (gdb) c
