+# XiUOS README
+
+[XiUOS](http://xuos.io/) (X Industrial Ubiquitous Operating System) 矽璓工业物联操作系统是一款面向工业物联场景的泛在操作系统，来自泛在操作系统研究计划。所谓泛在操作系统(UOS: Ubiquitous Operating Systems)，是支持互联网时代人机物融合泛在计算应用模式的新型操作系统，是传统操作系统概念的泛化与延伸。在泛在操作系统技术体系中，不同的泛在计算设备和泛在应用场景需要符合各自特性的不同UOS，XiUOS即是面向工业物联场景的一种UOS，主要由一个极简的微型实时操作系统(RTOS)内核和其上的智能工业物联框架构成，支持工业物联网(IIoT: Industrial Internet of Things)应用。

+
+## 硬件支持
+
+目前XiUOS支持ARM和RISC-V两种架构的微处理器:
+
+### ARM
+
+ARM架构系列的开发板有
+
+	aiit-arm32-board	stm32f407-st-discovery		stm32f407zgt6
+
+### RISC-V
+
+RISC-V架构系列的开发板有
+
+	aiit-riscv64-board		hifive1-rev-B		kd233		maix-go
+
+## 开发环境
+
+### 推荐使用：
+
+### 操作系统： [Ubuntu18.04](https://ubuntu.com/download/desktop)
+
+### 开发工具： [VSCode](https://code.visualstudio.com/)
+
+### 依赖包安装：
+
+```
+$ sudo apt-get install build-essential pkg-config
+$ sudo apt-get install gcc make libncurses5-dev openssl libssl-dev bison flex libelf-dev autoconf libtool gperf libc6-dev
+```
+
+### 编译工具链：
+
+ARM： arm-none-eabi，默认安装到Ubuntu的/usr/bin/arm-none-eabi-，使用如下命令行下载
+```shell
+$ sudo apt-get install gcc-arm-none-eabi
+```
+
+RISC-V: riscv-none-embed-，默认安装到Ubuntu的/opt/，下载源码并解压。[下载网址](https://github.com/ilg-archived/riscv-none-gcc/releases)
+
+```shell
+$ tar -zxvf gnu-mcu-eclipse-riscv-none-gcc-8.2.0-2.1-20190425-1021-centos64.tgz -C /opt/
+```
+
+### 烧写工具
+
+ARM：ST-LINK
+
+RISC-V：K-FLash
+
+**每种开发板分别对应board目录下的一个文件夹，具体编译及烧录步骤请参见board目录下对应文件夹下的README文件。**
