Overview
|
||
|
|
********
|
||
|
|
|
||
|
|
The RISCV32 QEMU board configuration is used to emulate the RISCV32 architecture.

Programming and Debugging
|
||
|
|
*************************
|
||
|
|
|
||
|
|
Applications for the ``qemu_riscv32`` 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_riscv32
|
||
|
|
: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
