| 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. |

| 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 |
| |
