.. zephyr:board:: qemu_rx

Overview

This board configuration will use QEMU to emulate the Renesas RXv1 platform.

This configuration provides support for the R5F562N8 MCU and below devices:

• On-chip memory (ROM 512KB, RAM 96KB)
• Interrupt Control Unit (ICUa)
• Compare Match Timer x 2CH (CMT0,1)
• Serial Communication Interface x 1CH (SCI0)

Hardware

Supported Features

.. zephyr:board-supported-hw::

Devices

System Clock

This board configuration uses a system clock frequency of 6 MHz generated by the CMT timer.

Serial Port

This board configuration uses a single serial communication channel on the SCI UART channel 0.

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_rx :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
