CC3200 OTA Service Pack以及MCU Image示例

时间：10-02 整理：3721RD 点击：

由于在官方的SDK里面使用的是dropbox做服务器来进行OTA升级，国内访问不了， 为了方便大家可以参考，下面是用国内的一个服务器来实现的OTA例程。

https://github.com/yhpan0613/SimpleLink-CC3200/releases/tag/cc3200_ota_servicepack_and_image_v1_0

这是整套的代码，是基于SDK 1.2.0的，例程的名称是ota_update_cn。

请注意在编译这个例程之前， simplelink_extlib/ota是需要重新编译的。

在服务器端的准备升级的MCU Image以及Service Pack根据协议要放在位置OTA/CC3200。待升级的文件列表以及它们的大小是存储在一个文件img.txt里面，文件格式如下：

      SP_SIGN:{f40_sys_servicepack.sig}

      SIGN_SIZE:{256}

      SERVICEPACK:{f43_sys_servicepack.ucf}

      SP_SIZE:{28236}

      MCU_IMG:{f80_sys_mcuimg.bin}

      MCU_SIZE:{36316}

冒号前面的字段是文件标识，后面的字段是文件名称， f是文件标识，后面的数字代表标识的含义如下：

  • 01 - The file is secured 
  • 02 - The file is secured with signature
  • 04 - The file is secured with certificate
  • 08 - Don't convert _sys_ into /sys/ for SFLASH 
  • 10 - Use external storage instead of SFLASH 
  • 20 - Reserved.
  • 40 - NWP should be reset after this download
  • 80 - MCU should be reset after this download

还有另外一个文件ver.txt， 里面存储的是MCU image和Service Pack存储的路径，格式如下：

“CDN_url”: http://SERVER_DOMAIN/OTA/CC3200/Vid01_Pid33_Ver18/,

Vid代表Vendor ID, Pid代表Product ID, Ver代表升级软件版本，OTA/CC3200目录下文件列表如下

Vid01_Pid33_Ver18下面文件列表如下：

      

 

sys_servicepack.sig代表service pack的签名文件，会存储在/sys/serverpack.sig。sys_servicepack.ucf是待升级的service pack文件，会存储在/sys/serverpack.ucf。sys_mcuimg.bin是待升级的MCU Image文件，会存储在/sys/mcuimg2.bin。在进行OTA前， /sys/mcuimg.bin需要烧录application_bootloader, /sys/mcuimg1.bin需要烧录当前运行的Image。当OTA升级结束后，application_bootloader将会加载mcuimg2去运行。然后在下一次OTA的时候，从云服务器上下载的Image会烧录到/sys/mcuimg1.bin，在设备重启后application bootloader会自动加载mcuimg1。

注意：服务器端的KeepAlive选项要设置成ON.

谢谢分享！

谢谢分享

强烈支持，期待你的后续！

以上关于是关于OTA的状态，欢迎提出改进意见，亦或者如果觉得想共享代码也是非常的欢迎。

你好，我想请问下ata_api.h下的#define OTASTAT_FILENAME "/sys/otastat.txt"      里面的"/sys/otastat.txt" 路径在哪里，是否需要修改？因为按上文中您分享的方法没有成功升级，而是 sl_extLib_OtaRun 一直返回-4，表示路径找不到。。

这个是在本地写的，就是在CC3200 FLASH上的路径。能否把DEBUG_PRINT的开关打开，具体在哪个API返回的错误，给出更多的log来分析一下。

这个项目工程是直接导入到CCS 里面吗？

你这个项目工程是CCS的吗？

C:\Users\Administrator\Downloads\SimpleLink-CC3200-cc3200_ota_servicepack_and_image_v1_0\example\ota_update_cn

你说直接用CCS 导入这个工程文件就可以了？

TI 工程师，你好：
**** Build Finished ****
Buildfile generation error occurred..
Referenced project 'ti_rtos_config' does not exist in the workspace. Project 'ota_update_os' may not build as expected.
Build stopped..

导入CCS工程后，编译的时候，提示了这个报错，你知道是什么原因吗？

从你的错误看是ti_rtos_config这个没有导入进去，你的ti_rtos_config, 你先把ti_rtos_config这个工程编译一下看看。

Yonghua您好：

我们这边搭了一个自己的服务器，路径相同什么都相同，访问Img.txt和ver.txt直接返回其文本，访问Vid01_Pid33_Ver18/下的三个文件时是返回文件，但是出现错误解决不了，具体错误如下

请问有服务器搭建的流程讲解吗？麻烦指导一下，谢谢~~

你好，我做的CC2538的芯片，要做到空中升级节点BIN文件，需要把OTA server搬到网关上，需要LIUNX的工具源码，请问如何能获取到，万分感谢

灌胶产品的EMC问题

Hi Pan:

我按照您的demo操作，发现总是在下载f80_sys_mcuimg.bin到15840bytes时pWriteFile就会出错！服务端不管是用您的或我自己搭建的都一样的结果，但是service pack可以更新成功。使用Uniflash烧录的文件：/sys/mcuimg.bin加载application_bootloader.bin，/sys/mcuimg1.bin加载ota_update_os.bin

请帮看下下面的log，问题出在哪里？谢谢！
