+# 从零开始构建矽璓工业物联操作系统：使用risc-v架构的gapuino 开发板
+
+[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。
+
+
+## 开发环境搭建
+
+### 推荐使用：
+
+**操作系统：** ubuntu18.04 [https://ubuntu.com/download/desktop](https://ubuntu.com/download/desktop)
+
+**开发工具推荐使用 VSCode   ，VScode下载地址为：** VSCode  [https://code.visualstudio.com/](https://code.visualstudio.com/)，推荐下载地址为 [http://vscode.cdn.azure.cn/stable/3c4e3df9e89829dce27b7b5c24508306b151f30d/code_1.55.2-1618307277_amd64.deb](http://vscode.cdn.azure.cn/stable/3c4e3df9e89829dce27b7b5c24508306b151f30d/code_1.55.2-1618307277_amd64.deb)
+
+### 依赖包安装：
+
+```
+$ sudo apt install build-essential pkg-config
+$ sudo apt install gcc make libncurses5-dev openssl libssl-dev bison flex libelf-dev autoconf libtool gperf libc6-dev  git
+```
+
+**源码下载：** XiUOS [https://forgeplus.trustie.net/projects/xuos/xiuos](https://forgeplus.trustie.net/projects/xuos/xiuos)
+
+新建一个空文件夹并进入文件夹中，并下载源码，具体命令如下：
+
+```c
+mkdir test  &&  cd test
+git clone https://git.trustie.net/xuos/xiuos.git
+```
+
+打开源码文件包可以看到以下目录：
+| 名称 | 说明 |
+| -- | -- |
+| application | 应用代码 |
+| board | 板级支持包 |
+| framework | 应用框架 |
+| fs | 文件系统 |
+| kernel | 内核源码 |
+| resources | 驱动文件 |
+| tool | 系统工具 |
+
+使用VScode打开代码，具体操作步骤为：在源码文件夹下打开系统终端，输入`code .`即可打开VScode开发环境，如下图所示：
+
+![vscode](img/vscode.jpg)
+  
+### 裁减配置工具的下载
+
+裁减配置工具：
+
+**工具地址：** kconfig-frontends [https://forgeplus.trustie.net/projects/xuos/kconfig-frontends](https://forgeplus.trustie.net/projects/xuos/kconfig-frontends)
+
+```c
+mkdir kfrontends  && cd kfrontends
+git  clone https://git.trustie.net/xuos/kconfig-frontends.git
+```
+
+下载源码后按以下步骤执行软件安装：
+
+```c
+cd kconfig-frontends
+ ./xs_build.sh
+```
+
+### 编译工具链：
+
+RISC-V: riscv-none-embed-，默认安装到Ubuntu的/opt/，下载源码并解压。[下载网址 http://101.36.126.201:8011/gnu-mcu-eclipse.tar.bz2](http://101.36.126.201:8011/gnu-mcu-eclipse.tar.bz2)
+
+```shell
+$ tar -xjf gnu-mcu-eclipse.tar.bz2 -C /opt/
+```
+
+将上述解压的编译工具链的路径添加到board/hifive1-rev-B/config.mk文件当中，例如：
+
+```
+export CROSS_COMPILE ?=/opt/gnu-mcu-eclipse/riscv-none-gcc/8.2.0-2.1-20190425-1021/bin/riscv-none-embed-
+```
+
+若已存在`export CROSS_COMPILE ?=xxxx`   应该将原有的语句注释，再写入上面的语句。
+
+# 在gapuino board 上创建第一个应用
+
+## 1.gapuino board 简介
+
+| 硬件 | 描述 |
+| -- | -- |
+|芯片型号| gap8 |
+|架构| RV32IMAC |
+|主频| 200+MHz |
+|片内SRAM| 512KB |
+| 外设 | UART、SPI、I2C |
+
+XiUOS板级当前支持使用UART。
+
+## 2. 代码编写与编译说明
+
+编辑环境：`VScode`
+
+编译工具链：`riscv-none-embed-gcc`
+
+使用`VScode`打开工程的方法有多种，本文介绍一种快捷键，在项目目录下将`code .`输入终端即可打开目标项目
+
+修改`applications`文件夹下`main.c`
+
+在输出函数中写入  Hello, world! \n 完成代码编辑。
+
+
+编译步骤：
+
+1.在VScode终端下执行以下命令，生成配置文件
+
+```
+make BOARD=gapuino menuconfig
+```
+
+2.在menuconfig界面配置需要关闭和开启的功能，按回车键进入下级菜单，按Y键选中需要开启的功能，按N键选中需要关闭的功能，配置结束后选择Exit保存并退出
+
+![menuconfig](img/menuconfig.png)
+
+3.继续执行以下命令，进行编译
+
+```
+make BOARD=gapuino
+```
+
+4.如果编译正确无误，build文件夹下会产生XiUOS_gapuino.elf、XiUOS_gapuino.bin文件。
+
+>注：最后可以执行以下命令，清除配置文件和编译生成的文件
+
+```
+make BOARD=gapuino distclean
+```
+
+## 3. 烧写及执行
+
+gapuino支持jtag，可以通过jtag进行烧录和调试。
+调试烧写需要下载gap sdk和openocd,下载配置方法参见以下文档：
+https://greenwaves-technologies.com/setting-up-sdk/
+
+在SDK 和openocd安装完成以后，按照如下步骤进行调试：
+
+1、进入sdk目录路径下
+```
+cd ~/gap_sdk 
+```
+
+2、在当前终端输入
+```
+source sourceme.sh 
+```
+出现如下图所示的界面，输入7选择单板名称；
+![choose](./img/choose_board.png)
+
+3、先按开发板的复位键，再在当前终端输入
+```
+gap8-openocd  -f interface/ftdi/gapuino_ftdi.cfg -f target/gap8.tcl -f tcl/jtag_boot_entry.tcl 
+```
+在当前终端连接openocd，连接如下图所示：
+![openocd](./img/openocd.png)
+
+4、打开一个新的终端，输入以下命令打开终端串口：
+```
+sudo apt install screen
+screen /dev/ttyUSB0 115200
+```
+
+5、打开一个新的终端，进入编译生成的elf路径,输入例如：
+```
+riscv32-unknown-elf-gdb build/XiUOS_gapuino.elf -ex "target remote localhost:3333"
+```
+结果如下图所示：
+![gdb](./img/gdb_load.png)
+
+6、再输入load，最后输入continue命令即可在串口终端看到系统运行界面，如下图所示：
+![terminal](./img/terminal.png)
+

+ * this file must provide:
+ *  -  A device-specific system configuration function, \ref SystemInit().
+ *  -  A global variable that contains the system frequency, \ref SystemCoreClock.
+ *
+ * The file configures the device and, typically, initializes the oscillator (PLL) that is part
+ * of the microcontroller device. This file might export other functions or variables that provide
+ * a more flexible configuration of the microcontroller system.
+ *
+ * \note Please pay special attention to the static variable \c SystemCoreClock. This variable might be
+ * used throughout the whole system initialization and runtime to calculate frequency/time related values.
+ * Thus one must assure that the variable always reflects the actual system clock speed.
+ *
+ * \attention
+ * Be aware that a value stored to \c SystemCoreClock during low level initialization (i.e. \c SystemInit()) might get
+ * overwritten by C libray startup code and/or .bss section initialization.
+ * Thus its highly recommended to call \ref SystemCoreClockUpdate at the beginning of the user \c main() routine.
