# OTA README
|
||||
|
||||
xiuos当前的ota功能允许应用bin文件可以通过4G实现远程的bin文件更新（限制：1、bin文件存放在设备SD卡并且应用从SD卡启动；2、暂且支持4G实现；3、暂时只支持aiit终端）。
|
||||
|
||||
## 文件说明
|
||||
|
||||
| 名称 | 说明 |
|
||||
| -- | -- |
|
||||
| ota.c| 设备OTA代码 |
|
||||
| ota_server.c | pc服务端的实例代码供参考 |
|
||||
|
||||
|
||||
## 使用说明
|
||||
xiuos的应用bin文件更新依赖上层的adapter框架，因此需要在menuconfig同时配置以下选项：
|
||||
1、ota开关APPLICATION_OTA打开；
|
||||
2、adapter的4G功能开关；
|
||||
3、拆分的应用启动SEPARATE_COMPILE开关从SD卡启动的配置开关APP_STARTUP_FROM_SDCARD。
