+
+## 2. 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)
+
+更新`ubuntu 18.04`源的方法:（根据自身情况而定，可以不更改）
+
+第一步:打开sources.list文件
+
+```c
+sudo vim /etc/apt/sources.list
+```
+
+第二步:将以下内容复制到sources.list文件
+
+```c
+deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
+deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
+deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
+deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
+deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
+deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
+deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
+deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
+deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
+deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
+```
+
+第三步:更新源和系统软件
+
+```c
+sudo apt-get update
+sudo apt-get upgrade
+```
+
+**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  git
+$ sudo apt install gcc make libncurses5-dev openssl libssl-dev bison flex libelf-dev autoconf libtool gperf libc6-dev
+```
+
+**XiUOS操作系统源码下载：** XiUOS [https://www.gitlink.org.cn/xuos/xiuos](https://www.gitlink.org.cn/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://gitlink.org.cn/xuos/xiuos.git
+```
+
+1、打开XiUOS源码文件包可以看到以下目录：
+| 名称 | 说明 |
+| -- | -- |
+| APP_Framework | 应用代码 |
+| Ubiquitous | 板级支持包,支持NuttX、RT-Thread和XiZi内核 |
+
+2、打开XiZi内核源码文件包可以看到以下目录：
+| 名称 | 说明 |
+| -- | -- |
+| arch | 架构代码 |
+| board | 板级支持包 |
+| fs | 文件系统 |
+| kernel | 内核源码 |
+| lib | 第三方库源码 |
+| 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：
+
+<div align= "center"> 
+<img src = ./img/vscode.jpg  width =1000>
+  </div>
+
+### 裁减配置工具的下载
+
+裁减配置工具：
+
+**工具地址：** kconfig-frontends [https://www.gitlink.org.cn/xuos/kconfig-frontends](https://www.gitlink.org.cn/xuos/kconfig-frontends)，下载与安装的具体命令如下：
+
+```c
+mkdir kfrontends  && cd kfrontends
+git clone https://gitlink.org.cn/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：
+
+ARM： arm-none-eabi(`gcc version 6.3.1`)，默认安装到Ubuntu的/usr/bin/arm-none-eabi-，使用如下命令行下载和安装。
+
+```shell
+$ sudo apt install gcc-arm-none-eabi
+```
+
+## 编译说明
+
+### 编辑环境：`Ubuntu18.04`
+
+### 编译工具链：`arm-none-eabi-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linux系统命令终端即可打开目标项目
+
+
+编译步骤：
+
+1.在VScode命令终端中执行以下命令，生成配置文件
+
+```shell
+cd ./Ubiquitous/Nuttx/app_match_nuttx
+source build.sh
+
+执行完毕会自动进入./Ubiquitous/Nuttx/nuttx下，继续执行
+
+sudo ./tools/configure.sh xidatong:nsh
+sudo make 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，配置结束后保存并退出（本例旨在演示简单的输出例程，所以没有需要配置的选项，双击快捷键ESC退出配置）
+
+![menuconfig](./img/menuconfig.png)
+
+退出时选择`yes`保存上面所配置的内容，如下图所示：
+
+![menuconfig1](./img/menuconfigexit.png)
+
+3.继续执行以下命令，进行编译
+
+```shell
+sudo make
+或
+sudo make -j8
+```
+
+make时加上V=1参数可以看到较为详细的编译信息，但是编译过程会比较慢。
+
+4.如果编译正确无误，会在当前目录下产生nuttx、nuttx.hex等文件。
+
+## 3. 烧写及运行
+
+### 3.1 烧写
+1、烧写工具：NXP MCU Boot Utility，可参考[https://github.com/JayHeng/NXP-MCUBootUtility](https://github.com/JayHeng/NXP-MCUBootUtility)
+
+2、xidatong开发板支持UART串口烧写程序，打开NXP MCU Boot Utility后，选择好芯片类型为i.MXRT105x，开发板上电，使用串口转USB线将开发板和PC连接，拨码开关设置为1 on 2 on 3 off 4 off，重新上电，选择对应的COM口和波特率（需关闭串口终端连接，确保该COM口空闲，否则会导致Utility工具连接失败），连接成功后，点击reconnect，等待NXP MCU Boot Utility中红色显示变成蓝色显示，则表示已正确识别并连接到了开发板。如下图所示：
+![NXPBootUtility_1](./img/NXPBootUtility_1.png)
+
+3、同时需要匹配xidatong开发板所使用的Flash型号，点击Boot Device Configuration，在Use Typical Device中选择Winbond_W25QxxxJV，然后点击ok。如下图所示：
+![flashconfig](./img/flashconfig.png)
+
+4、选择编译生成的nuttx文件路径(nuttx不带任何后缀，是一个elf文件)，按照图示步骤，将文件烧写至Flash中（若烧写无误，则下列绿色进度条会执行到底）。如下图所示：
+![NXPBootUtility_2](./img/NXPBootUtility_2.png)
+
+### 3.2 运行结果
+
+按照3.1烧写步骤执行后，将拨码开关设置为1 off 2 off 3 off 4 off，重新上电后，重新打开该COM口串口终端，若程序正常，则串口终端上会显示启动信息打印输出。如下图所示：
+![terminal](./img/terminal.png)

+ * regions) to trim it to fit better.

+ *                 adjustments for alignment.  Typical is 1KB.
+ *   ------ ----   Padded to 4KB
+ *   0x2040 0000:  User .data region.  Size is variable.
+ *   ------- ----  User .bss region  Size is variable.
+ *   0x2042 0000:  Beginning of kernel heap.  Size determined by
+ *                 CONFIG_MM_KERNEL_HEAPSIZE.
+ *   ------ ----   Beginning of user heap.  Can vary with other settings.

+ * Description:

+ *
+ * Input Parameters:
+ *   arg - The boardctl() argument is passed to the board_app_initialize()
+ *         implementation without modification.  The argument has no
+ *         meaning to NuttX; the meaning of the argument is a contract
+ *         between the board-specific initialization logic and the
+ *         matching application logic.  The value could be such things as a
+ *         mode enumeration value, a set of DIP switch switch settings, a
+ *         pointer to configuration data read from a file or serial FLASH,
+ *         or whatever you would like to do with it.  Every implementation
+ *         should accept zero/NULL as a default configuration.
+ *
+ * Returned Value:
+ *   Zero (OK) is returned on success; a negated errno value is returned on
+ *   any failure to indicate the nature of the failure.

+ * include/board.h and src/imxrt_autoleds.c. The LED is used to encode
+ * OS-related events as follows:
+ *
+ *   -------------------- ----------------------- ------
+ *   SYMBOL               Meaning                 LED
+ *   -------------------- ----------------------- ------
+ *
+ *   LED_STARTED       0  NuttX has been started  OFF
+ *   LED_HEAPALLOCATE  0  Heap has been allocated OFF
+ *   LED_IRQSENABLED   0  Interrupts enabled      OFF
+ *   LED_STACKCREATED  1  Idle stack created      ON
+ *   LED_INIRQ         2  In an interrupt         N/C
+ *   LED_SIGNAL        2  In a signal handler     N/C
+ *   LED_ASSERTION     2  An assertion failed     N/C
+ *   LED_PANIC         3  The system has crashed  FLASH
+ *   LED_IDLE             Not used
+ *
+ * Thus if the LED is statically on, NuttX has successfully  booted and is,

+ *   may be cause by the chip's MAC logic (in which case arch_phy_irq()) is
+ *   an appropriate name.  Other other boards, there may be no PHY interrupts
+ *   available at all.  If client attachable PHY interrupts are available
+ *   from the board or from the chip, then CONFIG_ARCH_PHY_INTERRUPT should
+ *   be defined to indicate that fact.
+ *
+ *   Typical usage:
+ *   a. OS service logic (not application logic*) attaches to the PHY
+ *      PHY interrupt and enables the PHY interrupt.
+ *   b. When the PHY interrupt occurs:  (1) the interrupt should be
+ *      disabled and () work should be scheduled on the worker thread (or
+ *      perhaps a dedicated application thread).
+ *   c. That worker thread should use the SIOCGMIIPHY, SIOCGMIIREG,
+ *      and SIOCSMIIREG ioctl calls** to communicate with the PHY,
+ *      determine what network event took place (Link Up/Down?), and
+ *      take the appropriate actions.
+ *   d. It should then interact the PHY to clear any pending
+ *      interrupts, then re-enable the PHY interrupt.
+ *
+ *    * This is an OS internal interface and should not be used from
+ *      application space.  Rather applications should use the SIOCMIISIG
+ *      ioctl to receive a signal when a PHY event occurs.
+ *   ** This interrupt is really of no use if the Ethernet MAC driver
+ *      does not support these ioctl calls.
+ *
+ * Input Parameters:
+ *   intf    - Identifies the network interface.  For example "eth0".  Only
+ *             useful on platforms that support multiple Ethernet interfaces
+ *             and, hence, multiple PHYs and PHY interrupts.
+ *   handler - The client interrupt handler to be invoked when the PHY
+ *             asserts an interrupt.  Must reside in OS space, but can
+ *             signal tasks in user space.  A value of NULL can be passed
+ *             in order to detach and disable the PHY interrupt.
+ *   arg     - The argument that will accompany the interrupt
+ *   enable  - A function pointer that be unused to enable or disable the
+ *             PHY interrupt.
+ *
+ * Returned Value:
+ *   Zero (OK) returned on success; a negated errno value is returned on
+ *   failure.

+ *   They are implementations of the select and status methods of the SPI

+ *   All other methods (including imxrt_lpspibus_initialize()) are provided

+ *
+ *   1. Provide logic in imxrt_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide imxrt_lpspi1/2/3select() and imxrt_lpspi1/2/3status()
+ *      functions in your board-specific logic.
+ *      These functions will perform chip selection and status operations
+ *      using GPIOs in the way your board is configured.
+ *   3. Add a calls to imxrt_lpspibus_initialize() in your low level
+ *      application initialization logic
+ *   4. The handle returned by imxrt_lpspibus_initialize() may then be used
+ *      to bind the SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).
