QEMU Emulation for Xtensa

Board Overview

Vendor:

QEMU, a generic and open source machine emulator and virtualizer

Architecture:

xtensa

SoC:

sample_controller32, dc233c

Overview

The QEMU board configuration is used to emulate the Xtensa architecture. This board configuration provides support for the Xtensa simulation environment.

Programming and Debugging

Use this configuration to run basic Zephyr applications and kernel tests in the QEMU emulated environment, for example, with the Basic Synchronization sample:

# From the root of the zephyr repository
west build -b qemu_xtensa/dc233c samples/synchronization
west build -t run

This will build an image with the synchronization sample app, boot it using QEMU, and display the following console output:
