+# OTA升级指导文档
+
+## 一、  下载代码程序源码
+
+git clone --branch prepare_for_master https://gitlink.org.cn/xuos/xiuos.git
+
+## 二、  编译bootloader固件
+
+进入到xiuos/Ubiquitous/XiZi_IioT目录下，以xidatong-arm32开发板为例，执行：
+
+make BOARD=xidatong-arm32 menuconfig
+
+依次进入Tool feature > OTA function > Enable support OTA function
+
+勾选如下编译选项:
+
+![](img/bootloader.jpg)
+
+
+退出menuconfig，执行make BOARD=xidatong-arm32进行bin包编译。
+
+最后在xiuos/Ubiquitous/XiZi_IIoT/build目录下编译出XiZi-xidatong-arm32-boot.bin文件:
+
+![](img/bootloader-bin.jpg)
+
+
+## 三、  Bootloader固件烧录
+
+Bootloader烧录需要使用NXP-MCUBootUtility工具，与xidatong-arm32整包烧录步骤一样，开发板拨码开关1和2拨回ON后，重新上电，NXP-MCUBootUtility工具点击Connect to ROM，然后起始地址设置为0x60000000，长度根据XiZi-xidatong-arm32-boot.bin大小来确定，最后选择bin文件的路径：
+
+![](img/MCUBootlUtility.jpg)
+
+
+最后点击Write(Auto Erase)进行烧写。
+
+## 四、  自研平台上新增设备
+
+（1）登录自研平台，网址[ http://115.238.53.59:9898//](http://192.168.141.13:9528/),账户密码需要向管理员索取:
+
+![](img/platform1.jpg)
+
+![](img/platform2.jpg)
+
+
+（2）创建设备，在登录后的界面左侧变蓝进行设备新增:
+
+![](img/add-device1.jpg)
+
+![](img/add-device2.jpg)
+
+
+
+
+创建完成后，在未激活的设备列表里可以看到新增的设备。
+
+这里的设备序列号我们记下来，编译阶段需要用。我们需要平台相关的五个信息用于设备登录:
+
+ CLIENTID: "xidatong0001",
+
+ USERNAME: "xiuosiot",
+
+ PASSWORD: "xiuosiot"
+
+ PLATFORM_SERVERIP: "115.238.53.59"
+
+PLATFORM_SERVERPORT: "1883"
+
+## 五、  编译APP应用程序固件
+
+再次进入到xiuos/Ubiquitous/XiZi_IioT目录下，依次执行
+
+make BOARD=xidatong-arm32 distclean
+
+make BOARD=xidatong-arm32 menuconfig
+
+如果需要基于阿里云平台进行OTA升级，编译APP应用程序固件需要使能如下选项:
+
+（1）进入 Tool feature > OTA function > Enable support OTA function 
+
+选择编译APP:
+
+![](img/app1.jpg)
+
+![](img/app2.jpg)
+
+
+（2）选择进行OTA升级的方式，选择IOT平台:
+
+![](img/IOT1.jpg)
+
+![](img/IOT2.jpg)
+
+
+（3）进入 APP_Framework > app lib > lib using MQTT > Enable support MQTT function 使能MQTT，进入Choose xiuos platform or Alibaba Cloud platform选择xiuos platform:
+
+![](img/MQTT1.jpg)
+
+![](img/MQTT2.jpg)
+
+![](img/MQTT3.jpg)
+
+
+进入xiuos platform mqtt connection parameter configuration配置参数,将第四步获取到的5个信息填入:
+
+![](img/MQTT4.jpg)
+
+![](img/MQTT5.jpg)
+
+
+退出menuconfig，执行make BOARD=xidatong-arm32进行bin包编译。
+
+最后在xiuos/Ubiquitous/XiZi_IIoT/build目录下编译出XiZi-xidatong-arm32-app.bin文件:
+
+![](img/app-bin.jpg)
+
+
+第一次烧写app文件通过iap的方式，烧写完后，设备会自动登录到xiuos管理平台，与平台建立连接，如下图所示，设备端串口显示登录成功:
+
+![](img/shell.jpg)
+
+
+在设备管理→设备新增→已激活设备列表里可以看到该设备:
+
+![](img/device-list.jpg) 
+
+
+另:设备断开连接时该设备在未激活设备列表中。
+
+## 六、  利用xiuos管理平台进行OTA升级
+
+（1）上传bin文件到管理平台
+
+查看当前设备的固件版本:
+
+![](img/version.jpg)
+
+
+
+
+当前设备固件的版本为001.000.006，接下来设置固件版本要比这个大。平台左边栏选择OTA升级，添加升级包:
+
+![](img/add-new-bin.jpg)
+
+
+填写固件版本信息:
+
+![](img/new-version.jpg)
+
+
+选择固件进行上传:
+
+![](img/binfile.jpg)
+
+
+上传后点击验证，固件完成验证就可以进行升级了。
+
+（2）添加完成后，在升级包列表处选择刚添加的升级包点击升级，跳出的界面里新增升级任务:
+
+![](img/addtask1.jpg)
+
+
+在跳出的界面选择新增升级任务:
+
+![](img/addtask2.jpg)
+
+
+填入升级设备的id，就是创建设备时的CLIENTID，进行设备在线监测，显示设备在线后，点击提交。终端设备连接串口助手，可以看到升级进度:   
+
+![](img/progress1.jpg)
+
+
+升级过程中，平台端显示进行中:
+
+![](img/progress2.jpg)
+
+
+（3）固件烧录完成后自动并登录xiuos管理平台，上报最新的版本:
+
+![](img/newversion-report1.jpg)
+
+![](img/newversion-report2.jpg)
+
+
+刷新固件升级记录，显示成功，升级成功:
+
+![](img/success.jpg)
+
+
+至此，升级完成。
