块请求应答
emberAfOtaStorageFinishDownloadCallback(offset); //完成下载
continueImageVerification(EMBER_AF_IMAGE_UNKNOWN); 、、映象的状态，为不知道
}
2：
recordUpgradeStatus(BOOTLOAD_STATE_VERIFY_IMAGE); 、、核对映象

3：核对成功
downloadAndVerifyFinish(EMBER_AF_OTA_DOWNLOAD_AND_VERIFY_SUCCESS) 核对成功

请求服务器去升级，发送升级结束，如果没回，就强制升级
4：网关回了什么时候升级
