OTA分析

还要修改一个地方就是PY文件，也要把相对应的固件版本更新下。

 emberAfPluginOtaClientStackStatusCallback  //若是不想开机启动升级，要把这里屏蔽掉

 

void emberAfPluginOtaClientStackStatusCallback(EmberStatus status)
{
return ;
#if defined(EMBER_AF_PLUGIN_OTA_CLIENT_AUTO_START)

if (status != EMBER_NETWORK_UP

}

// EMAPPFWKV2-1516: make sure we don't have a delay time of 0 seconds.
if (randomDelaySeconds == 0) {
randomDelaySeconds = 1;
}
recordUpgradeStatus(BOOTLOAD_STATE_DELAY);
//otaPrintln("Delaying %d seconds before starting OTA client", randomDelaySeconds);

//=======网关进来的消息处理===========

static EmberAfStatus commandParse(bool defaultResponse,
EmberAfClusterCommand* message)

startDownload 、、启动下载

recordUpgradeStatus(BOOTLOAD_STATE_DOWNLOAD);

startDownload  、、这里面是正式开始下载

｛

continueImageDownload开始下载

｝

//==========

 

1:上电复位

    emberAfPluginEepromInitCallback(); 

检测外部SPI 存储器在不在，

2：簇初始化函数

emberAfOtaBootloadClusterClientInitCallback（）

｛

emAfOtaStorageEepromInit（）；若是FLASH不在，这里会让代码崩溃

｝

若是有一个高版本的文件在FLASH中，storageHasFullImage会为1.

3：当网络起来的时候，会触发OTA客户端的一些处理流程：这里是入口很是关键

#define EMBER_AF_GENERATED_PLUGIN_STACK_STATUS_FUNCTION_DECLARATIONS \
void emberAfPluginOtaClientStackStatusCallback(EmberStatus status); \

｛   

  这个里面要修改一下，否则启动会很慢

      randomDelaySeconds=0;改为0秒就能够了，实际会1秒以后触发

      currentBootloadState = BOOTLOAD_STATE_DELAY;

     waitingForResponse=0；没有等待相应

     setTimer（延时启动），触发函数

     nextEventTimer = 0;  、、超时处理下载文件时候

｝

4：setTimer延时触发的就是下面这个函数；

   emberAfOtaBootloadClusterClientTickCallback

｛

   otaClientTick（）；

｝

 

5：OTA运行的正式启动的第一步

     currentBootloadState = BOOTLOAD_STATE_DELAY;

   startServerDiscovery（）启动服务发现，就是去找OTA服务器、、2秒时间超时处理

   waitingForResponse = true;、、等待接收

    setTimer(10分钟);

    emAfOtaClientServiceDiscoveryCallback 当收到网关回的信息，会进入这

｛

    waitingForResponse = false;、、正常会清掉

     若是没有找到服务器，会过10分钟，继续寻找

    若是找到了：

    serverEndpoint = epList->list[0];
    serverNodeId = result->matchAddress;

     getPartnerLinkKey();;获取LINKKEY

 

  ｝

 

若是SPI里有一个更新的

EMBER_AF_PLUGIN_OTA_CLIENT_VERIFY_DELAY_MS  就检测完整性10MS 这个能够一改

先不考虑FLSAH里有一个更高版本的文件。

 

6：找服务器的IEEE地址

recordUpgradeStatus(BOOTLOAD_STATE_GET_SERVER_EUI);

determineNextState  决定下一个作什么

 recordUpgradeStatus(BOOTLOAD_STATE_QUERY_NEXT_IMAGE);

查询下一个映象文件，超时5分钟

接收函数处理

 

 

1：进来的消息处理

bool emAfProcessClusterSpecificCommand(EmberAfClusterCommand *cmd)

｛ emberAfOtaClientIncomingMessageRawCallback(cmd))

 ｝

 

2：

bool emberAfOtaClientIncomingMessageRawCallback(EmberAfClusterCommand* message)
{
commandParse(false, // default response?
}

3：

waitingForResponse = false;

imageBlockResponseParse(message->buffer,index + defaultResponse,message->bufLen);

 continueImageDownload();

sendMessage(commandId,0, // upgrade end status (ignored) timer)

waitingForResponse = true;

emberAfSendCommandUnicast(EMBER_OUTGOING_DIRECT, serverNodeId);

 setTimer(timer);  、、超时处理
