自己的 ota upgrade server

[ESP_Faye]

Hi,

master-device-key.bin is only needed when you need to use Espressif Cloud.

If you are using your own server, master-device-key.bin need not to be written into flash.

You can just download
0x00000 boot_v1.3(b3)
0x01000 user1.1024.new.bin
0xFC000 esp_init_data_default.bin
0xFE000 blank.bin

If your problem is still unsolved, please offer the capture picture of your flash download tool while you burning images into flash.

Please using Espressif Official flash download tool http://bbs.espressif.com/viewtopic.php?f=7&t=25

Hi,

when running user1.bin , please download user2.bin.

Could you offer your test code and your bin files? I'll download and have a try.

what's your SDK version ?

[alexchang]

sent you already, thanks!

我目前是这么做的供参考：
实现一个http下载将bin2放对位置（4KB + (FlashSize) / 2)，后执行
system_upgrade_flag_set(2);
system_upgrade_reboot();
完成升级

Hi, alex,

please have a look on document "99C-ESP8266-OTA_UPGRADE" here http://bbs.espressif.com/viewtopic.php?f=21&t=413

it seems that you compiled user2.bin in a wrong way.

試了許久，原廠的升級函數，在我這邊，當我處於 0x81000 user2 去升級 0x01000 user1 的時候，都會引起當機，而且重開後就無法正常開機了。

[alexchang]

好像找原因了，不使用 boot 增強模式就都可以正常更新，只要進入增強模式， user2 升級 user1 就會當機（一開始下載就當了）。

測試情境是這樣的：
完全重寫 rom ，使用
boot_v1.3(b3).bin
blank.bin
esp_init_data_default.bin
user1.bin
這幾個檔案。
接著 ota 升級 user2，升級完用 增強模式開機進入 user2，隨後不重啟，馬上繼續 ota 升級 user1，然後就會看到當機的狀況（一開始下載就當了）。
