+# QEMU/AArch64 VIRT BSP Introduction
+
+[中文页](README_zh.md) | English
+
+## 1. Introduction
+
+The AArch64 execution state was introduced with the ARMv8 ISA for machines executing A64 instructions. This project ported RT-Thread on QEMU AArch64 VIRT machine.
+
+## 2. Compiling
+
+Usage ARM Developer GNU ToolChain, it support Linux and Windows:
+```
+https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads/
+```
+Download the `xxx-aarch64-none-elf` of x86_64 hosted platform，set the `RTT_EXEC_PATH` is system environment after decompress the binary.
+
+Enter directory `rt-thread/bsp/qemu-virt64-aarch64` and input:
+```
+scons
+```
+
+## 2. Execution
+
+The project execution tool is `qemu-system-aarch64`
+
+Download Windows platform from website:
+```
+https://www.qemu.org/download/
+```
+On Linux platform (Ubuntu, Deepin and so on), install QEMU by apt.
+```
+sudo apt update
+sudo apt install qemu-system-arm
+```
+
+Run qemu.bat or qemu.sh in terminal:
+```
+heap: [0x40042aa0 - 0x40142aa0]
+
+ \ | /
+- RT -     Thread Operating System
+ / | \     4.0.4 build Aug  6 2021
+ 2006 - 2021 Copyright by rt-thread team

+# QEMU/AArch64 VIRT板级支持包说明
+
+中文页 | [English](README.md)
+
+## 1. 简介
+
+AArch64是一种采用ARMv8 ISA，用于执行A64指令的机器的64位执行模式。本工程是在QEMU的AArch64 VIRT版本上进行的一份移植。
+
+## 2. 编译说明
+
+建议使用ARM Developer GNU交叉编译工具链，目前支持Linux/Windows平台：
+```
+https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads/
+```
+下载x86_64 Hosted平台下载对应的`xxx-aarch64-none-elf`二进制包，解压后设置`RTT_EXEC_PATH`环境变量为该编译器的bin目录下即可。
+
+进入到`rt-thread/bsp/qemu-virt64-aarch64`目录进行输入：
+```
+scons
+```
+可以看到正常生成`rtthread.elf`与`rtthread.bin`文件。
+
+## 3. 执行
+
+本工程执行环境为`qemu-system-aarch64`模拟器
+
+Windows平台下，可以在此获取到QEMU：
+```
+https://www.qemu.org/download/
+```
+Linux平台下，以Ubuntu、Deepin系列发行版为例，可通过该命令安装QEMU：
+```
+sudo apt update
+sudo apt install qemu-system-arm
+```
+
+在终端执行qemu.bat或qemu.sh可以看到程序运行：
+```
+heap: [0x40042aa0 - 0x40142aa0]
+
+ \ | /

+```
+
+## 4.支持情况
+
+| 驱动 | 支持情况  |  备注  |
+| ------ | ----  | :------:  |
+| UART | 支持 | UART0 |
