Introduction

The repository is mainly developed by OpenHarmony community, rather than the typical certain manufacturer, mainly including the development of QEMU products with characteristics such as graphics, soft bus, etc.

Software Architecture

Graphic display product samples of virt platform supporting QEMU's ARMv7-a architecture, samples of virt platform supporting RISC-V architecture, and samples of Cortex-M4 architecture.

Installation

QEMU Install Guide

Usage

1. run command hb set to select the product target

ohos
 > qemu_small_system_demo
   qemu_mini_system_demo

qemu_small_system_demo indicates small system product demo, it contains system components, such as graphic, foundation, etc.

qemu_mini_system_demo indicates mini system product demo, it contains system components, such as samgr, hilog, etc.

2. run command hb build to start building。

3. To run the image with qemu. In details,

3.1 qemu_small_system_demo target,

./qemu-init
./qemu-run

use vnc-client to connect the host's 5920 port.

3.2 qemu_mini_system_demo target,

cd device/qemu/arm_mps2_an386
./qemu_run.sh ../../../out/arm_mps2_an386/bin/liteos
