-## 1. 简介
+[中文页](README_ZH.md) | English
-RISC-V是一种开放和免费的指令集体系结构(ISA)。本工程是在QEMU的RISCV64 VIRT版本上进行的一份移植。
+RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. This project ported RT-Thread on QEMU RISCV64 VIRT machine.
-## 2. 编译说明
+## 1. Compiling
+
+Download the cross compiler tool chain, it is recommended to use the sifive tool chain.
-首先可以下载交叉编译工具链,建议采用sifive的工具链进行编译。
```
https://www.sifive.com/software
```
-选择对应的平台即可。
-这里推荐在Ubuntu上进行开发工作。
+Select the fitting platform, we recommend Ubuntu.
-解压工具链到指定的目录。
+Unzip the tool chain to the specified directory.
```
export RTT_EXEC_PATH=~/gcc/bin
```
-进入到`rt-thread/bsp/qemu-riscv-virt64`目录进行输入
+Enter `rt-thread/bsp/qemu-riscv-virt64` directory and input
+
```
scons
```
-可以看到正常生成`rtthread.elf`与`rtthread.bin`文件。
-## 3. 执行
+ `rtthread.elf` and `rtthread .bin` files are generated.
-本工程提供了riscv64的两种可配置运行模式,默认运行在M-Mode下。
+## 2. Execution
-*M-Mode*
+The project provides two configurable operating modes for riscv64, defaults to run under M-Mode.
-首先安装`qemu-system-riscv64`。
+***M-Mode***
+
+Firstly, install the `qemu-system-riscv64`.
```
sudo apt install qemu-system-misc
```
-直接输入
+
+Then enter
+
```
./qemu-nographic.sh
```
-可以看到程序运行
+
+You'll see Project start running

-保存后,重新`scons`编译即可。
-要让rt-thread运行在S-Mode,首先需要启动opensbi,然后通过opensbi启动rt-thread。
+Save it and compile `scons`.
+
+To get RT-Thread running in S-Mode, enable the opensbi, and then start up the RT-Thread through opensbi.
-自行编译的qemu或者下载的高版本的qemu内置opensbi,执行`./qemu-nographic-smode.sh`即可正常运行。
+Compile qemu or downloaded premiere-version qemu that built-in opensbi, then executing `./qemu-nographic-smode.sh` can get it successfully running.
-通过`sudo apt install qemu-system-misc`安装的qemu版本较低,可自行编译opensbi。
+The qemu installed with `sudo apt install qemu-system-misc` is an ordinary-version and may compile the opensbi on its own.
```
