Building

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

.. tabs::

.. group-tab:: S7

  .. zephyr-app-commands::
     :zephyr-app: samples/hello_world
     :board: hifive_unmatched/fu740/s7
     :goals: build

.. group-tab:: U74

  .. zephyr-app-commands::
     :zephyr-app: samples/hello_world
     :board: hifive_unmatched/fu740/u74
     :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:

.. group-tab:: S7

  .. zephyr-app-commands::
     :zephyr-app: samples/hello_world
     :board: hifive_unleashed//s7
     :goals: flash

.. group-tab:: U74

  .. zephyr-app-commands::
     :zephyr-app: samples/hello_world
     :board: hifive_unmatched///u74
     :goals: flash
