.. zephyr:board:: qemu_cortex_a53
Overview
This board configuration will use QEMU to emulate a generic Cortex-A53 hardware platform.
This configuration provides support for an ARM Cortex-A53 CPU and these devices:
Hardware
.. zephyr:board-supported-hw::
This board configuration uses a system clock frequency of 62.5 MHz.
This board configuration uses a single serial communication channel with the CPU's UART0.
The following platform features are unsupported:
Programming and Debugging
.. zephyr:board-supported-runners::
Use this configuration to run basic Zephyr applications and kernel tests in the QEMU
emulated environment, for example, with the :zephyr:code-sample:synchronization sample:
.. zephyr-app-commands:: :zephyr-app: samples/synchronization :host-os: unix :board: qemu_cortex_a53 :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

Exit QEMU by pressing :kbd:CTRL+A :kbd:x.
Refer to the detailed overview about :ref:application_debugging.
The board supports the QEMU built-in Ethernet adapter to connect to the host
system. See :ref:networking_with_eth_qemu for details.
It is also possible to use SLIP networking over an emulated serial port. Although this board only supports a single UART, so subsystems like logging and shell would need to be disabled, therefore this is not directly supported.
