OTA分析

還要修改一個地方就是PY文件，也要把相對應的固件版本更新下。

 emberAfPluginOtaClientStackStatusCallback  //若是不想開機啓動升級，要把這裏屏蔽掉

//=======網關進來的消息處理===========

static EmberAfStatus commandParse(bool defaultResponse,
EmberAfClusterCommand* message)

startDownload 、、啓動下載

recordUpgradeStatus(BOOTLOAD_STATE_DOWNLOAD);

startDownload  、、這裏面是正式開始下載

｛

continueImageDownload開始下載

｝

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

 

1:上電覆位

    emberAfPluginEepromInitCallback(); 

檢測外部SPI 存儲器在不在，

2：簇初始化函數

emberAfOtaBootloadClusterClientInitCallback（）

｛

emAfOtaStorageEepromInit（）；若是FLASH不在，這裏會讓代碼崩潰

｝

若是有一個高版本的文件在FLASH中，storageHasFullImage會爲1.

3：當網絡起來的時候，會觸發OTA客戶端的一些處理流程：這裏是入口很是關鍵

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

｛   

  這個裏面要修改一下，否則啓動會很慢

      randomDelaySeconds=0;改爲0秒就能夠了，實際會1秒以後觸發

      currentBootloadState = BOOTLOAD_STATE_DELAY;

     waitingForResponse=0；沒有等待相應

     setTimer（延時啓動），觸發函數

     nextEventTimer = 0;  、、超時處理下載文件時候

｝

4：setTimer延時觸發的就是下面這個函數；

   emberAfOtaBootloadClusterClientTickCallback

｛

   otaClientTick（）；

｝

 

5：OTA運行的正式啓動的第一步

     currentBootloadState = BOOTLOAD_STATE_DELAY;

   startServerDiscovery（）啓動服務發現，就是去找OTA服務器、、2秒時間超時處理

   waitingForResponse = true;、、等待接收

    setTimer(10分鐘);

    emAfOtaClientServiceDiscoveryCallback 當收到網關回的信息，會進入這

｛

    waitingForResponse = false;、、正常會清掉

     若是沒有找到服務器，會過10分鐘，繼續尋找

    若是找到了：

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

     getPartnerLinkKey();;獲取LINKKEY

 

  ｝

 

若是SPI裏有一個更新的

EMBER_AF_PLUGIN_OTA_CLIENT_VERIFY_DELAY_MS  就檢測完整性10MS 這個能夠一改

先不考慮FLSAH裏有一個更高版本的文件。

 

6：找服務器的IEEE地址

recordUpgradeStatus(BOOTLOAD_STATE_GET_SERVER_EUI);

determineNextState  決定下一個作什麼

 recordUpgradeStatus(BOOTLOAD_STATE_QUERY_NEXT_IMAGE);

查詢下一個映象文件，超時5分鐘

接收函數處理

 

 

1：進來的消息處理

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);  、、超時處理
