|
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:
|
|
|
|
.. code-block:: console
|
|
|
|
openocd -c 'bindto 0.0.0.0' \
|
|
-f boards/riscv/hifive_unmatched/support/openocd_hifive_unmatched.cfg
|
|
