| RISCV32E Emulation (QEMU) |
| ######################### |
| |
| Overview |
| ******** |
| |
| The RISCV32E QEMU board configuration is used to emulate the RISCV32 (RV32E) architecture. |
| |
| Programming and Debugging |
| ************************* |
| |
| Applications for the ``qemu_riscv32e`` board configuration can be built and run in |
| the usual way for emulated boards (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| Flashing |
| ======== |
| |
| While this board is emulated and you can't "flash" it, you can use this |
| configuration to run basic Zephyr applications and kernel tests in the QEMU |
| emulated environment. For example, with the :ref:`synchronization_sample`: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/synchronization |
| :host-os: unix |
| :board: qemu_riscv32e |
| :goals: run |
| |
| This will build an image with the synchronization sample app, boot it using |
| QEMU, and display the following console output: |
| |
| .. code-block:: console |
