YoC RTOS 实战：FOTA系统升级

作者@budbool原文链接：https://bbs.aw-ol.com/topic/1526/1. 准备工作

建议在操作前先阅读以下技术文章：
Lichee D1 dock 开发板用户指南
Lichee D1 dock 开发板快速上手教程

2. 示例介绍

本文介绍如何在D1开发板上进行FOTA升级。

FOTA 是 Firmware Over the Air 的缩写，即固件空中升级，最常见的就是手机固件的升级。固件的定义范围比较模糊，windows操作系统升级、手机升级、嵌入式系统、单片机控制程序等都的远程升级可以笼统地称为FOTA。用这种方式，设备厂商可以更加快速地进行系统软件的迭代；能够更加快速地向市场推出具有新功能的设备并以此提高用户对其设备的满意度。

下面我们以fota_demo为例来介绍如何进行FOTA升级。

3. 示例获取

3.1 通过剑池CDK(以下简称CDK)获取
双击打开CDK，点击工具栏最右侧的平头哥图标。点击新建工程按钮。

在搜索栏里输入fota_demo, 在结果里选择fota_demo，点击右侧的创建工程，版本选择v7.5.1。

3.2 通过命令行获取

docker-ubuntu18:~$ mkdir testdocker-ubuntu18:~$ cd testdocker-ubuntu18:~$ yoc initdocker-ubuntu18:~$ yoc install sdk_app_d1 -b v7.5.1Start to install components...sdk_app_d1 (v7.5.1), clone https://gitee.com/yocop/sdk_app_d1.git ...…… (省略) ……d1_evb (v7.5.1), clone https://gitee.com/yocop/d1_evb.git ...chip_d1 (v7.5.1), clone https://gitee.com/yocop/chip_d1.git ...Download components finish.docker-ubuntu18:~/test$ lsboards components solutions
4. 示例演示

我们分成3个大的步骤进行介绍：

不同版本固件的生成
OCC固件添加，升级策略配置
设备端配置参数，下载固件并进行系统的升级

请注意：以下出现的方案目录指的是solutions/fota_demo这个文件夹下。

4.1 编译生成不同版本固件
4.1.1 基础镜像包1.0.0生成
在示例获取那个章节我们已经把fota_demo工程拉取下来了，接下来我们要编译这个工程并生成相应的镜像包。

如下图所示，点击红色方框处按钮进行编译。

编译结束之后，会在方案目录的generated下生成images.zip包。

如下所示，打开方案目录。将这个images.zip拷贝到上级目录(方案目录)并重命名为images_1.0.0.zip。

4.1.2 镜像包1.1.1版本生成
可以在方案的app/src/app_main.c文件中加个打印保存文件，并重新编译。将生成的generated/images.zip拷贝到方案目录，并重命名为images_1.1.1.zip，作为高版本。

4.2 OCC版本管理
4.2.1 创建产品，获取许可证
注册登陆平头哥芯片开放社区（OCC）后，进入到控制台中

在平头哥芯片开发社区上创建产品，在控制台->我的产品->添加产品，如下图所示，点击提交按钮。

点击编辑按钮

选择许可证，点击生成按钮，稍等刷新下即可

如下图所示，表示开发许可证已经生成完毕

4.2.2 上传镜像包至OCC服务器，并发布
在我的产品->编辑->FOTA页面选择添加固件

点击提交按钮

点击红色方框

点击发布按钮

返回之后，发布状态就会变成已发布，如果状态未变，可以再次刷新下。

发布1.1.1版本

提交完毕之后，选择1.1.1版本那一行进行发布。发布成功之后，服务器就会生成FOTA固件了。

4.2.3 云端选择升级策略
如右边红色框框，添加标签：

下图中的CID的值后面需要用到，请先记录下来

选择升级策略：

选择刚才写的标签，并提交：

到此为止，云端的配置基本结束了。

4.3 设备检测升级
4.3.1 将发布的镜像包下载到本地
点击红色框图位置下载镜像包到本地

4.3.2 基础版本固件烧录
选择通过CDK或者全志工具进行烧录。

通过CDK烧录
将下载过来的镜像包解压，并从hex目录取出total_image.hex文件，放到方案目录的generated目录下。

切换到CDK工程，点击红色方框处按钮开始烧录。

烧录过程中。。。

烧录完毕

通过全志工具烧录

比如从OCC上下载过了的压缩包名字为xx_factory.zip。在方案目录下，打开Windows的cmd环境，执行以下命令：packimg_win.bat xx_factory.zip，执行成功之后会有提示：Create yoc_rtos_xx_factory_16M.img in out directory Success!。然后通过全志烧录工具把yoc_rtos_xx_factory_16M.img进行烧录到开发板。

按住FEL按钮，重新上电后，重启后固件开始烧录，直到完成。

如果当前镜像支持xfex模式烧写，直接在串口命令行执行“xfex"命令，再执行"reboot"命令进行重启，重启后固件开始烧录，直到完成。

按复位键启动的打印如下，可以看到当前的版本为1.0.0的版本

4.3.3 设备端设置deivce_id/model，接收固件**
我们需要设置一些参数才能联网并且接受新的固件。
WiFi设置

通过串口终端输入：
kv set wifi_ssid kv set wifi_psk
your_wifi_ssid：你的wifi名字
your_wifi_password：你的wifi密码
设备信息设置

通过串口终端输入：
kv set device_id kv set model d1fota
cid：即4.2.3章节图片中提到的CID的值
model：即4.1章节中的产品型号值
设置完毕之后按开发板上的复位键重启。
4.3.4 设备端完成固件接收，进入系统升级
请确保设备联网成功。
设备检测到新版本的打印：

至此，说明整个FOTA升级已经成功完成了。
5. 注意事项
5.1 分区配置
使用升级功能需要指定升级包的存储区域。配置文件：configs/config.yaml
mtb_version: 4
chip: d1
diff:
fota_version: 0
ram_buf: 50 #DEC KB ( max ram need)
flash_buf: 16 #DEC KB ( buffer size)
flash_sector: 4096 #DEC byte ( flash sector)
diff_mode: 010 #BIN
double_control: 1
flash:
base_address: 0 # 存储基地址，比如FLASH的基地址
sector: 4096 # Bytes
size: 16777216 # 4096 $(sector count) * sector
partitions:
{ name: boot0, address: 0x000000, size: 0x00C000 } # don't touch
{ name: gpt, address: 0x00C000, size: 0x004000 } # don't touch
{ name: boot, address: 0x010000, size: 0x025000 }
{ name: imtb, address: 0x035000, size: 0x002000 }
{ name: prim, address: 0x037000, size: 0x400000, verify: true, update: FULL }
{ name: lfs, address: 0x437000, size: 0x700000 }
{ name: misc, address: 0xB37000, size: 0x410000 }
{ name: kv, address: 0xF47000, size: 0x004000 }
{ name: kp, address: 0xF4B000, size: 0x001000 }
对需要升级的分区加上update字段。

分区说明

6. 总结
以上即为整个FOTA升级示例详细的操作说明。有关FOTA升级相关的代码主要是在app/src/cop_fota.c文件中。实际应用过程中需要做好版本的管理。
