Bin Files Description
Using 1024KB flash size as example
if you want it to support upgrade firmware through Wi-Fi, you need to compile and download bins:
(1) blank.bin; provided in SDK and to be burned to flash 0xFE000;
(2) boot.bin, provided in SDK and to be burned to flash 0x00000;
(3) user1.bin, compiled by the steps said above and to be burned to flash 0x01000;
PS.
(1) boot_v1.5 is a new version of boot.bin which is recommended.
(2) In general, we don't burn user2.bin to flash, but upgrade it through Wi-Fi.
(3) if you are using Espressif Cloud,
master_device_key.bin, applied for through Espressif server;
if you are using your own server, this master_device_key.bin is not needed.
if you need not it to support upgrade firmware through Wi-Fi, you can compile and download bins:
(1) blank.bin; provided in SDK and to be burned to flash 0xFE000;
(2) eagle.flash.bin, compiled by the steps said above and to be burned to flash 0x00000;
(3) eagle.irom0text.bin, compiled by the steps said above and to be burned to flash 0x40000;
PS.
if you are using Espressif Cloud,
master_device_key.bin, applied for through Espressif server;
if you are using your own server, this master_device_key.bin is not needed.
NOTE: This FW cannot upgrade!

Bin 烧录介绍
烧录地址以 1024KB flash 为例
如果您希望可以通过网络进行软件升级（云端升级），编译并烧录如下bin：
(1) blank.bin，由 Espressif 提供，烧录到 0xFE000 地址；
(2) boot.bin，由 Espressif 提供，烧录到 0x00000 地址；
(3) user1.bin，如上编译生成，烧录到 0x01000 地址；
说明：
烧录补充.
(1) 推荐编译及烧录时，使用最新版本的 boot（目前为 boot_v1.5）
(2) 一般不需要烧录 user2.bin 到 Flash； user2.bin 可通过云端升级。
(3) 如果您使用 Espressif 的云端服务器，
master_device_key.bin，向 Espressif 云端服务器申请，
如果您使用自己的服务器，则不需要烧录 master_device_key.bin
如果您不需要通过网络进行软件升级（云端升级），编译并烧录如下bin：
(1) blank.bin，由 Espressif 提供，烧录到 0xFE000 地址；
(2) eagle.flash.bin，如上编译生成，烧录到 0x00000 地址；
(3) eagle.irom0text.bin，如上编译生成，烧录到 0x40000 地址；
说明：
如果您使用 Espressif 的云端服务器，
master_device_key.bin，向 Espressif 云端服务器申请，
如果您使用自己的服务器，则不需要烧录 master_device_key.bin
注意：这样编译烧录的软件，不能云端升级！
Note: The steps below are for ESP8266_SDK_V0.9.4 and earlier version. Refer to post above for ESP8266_SDK_V0.9.5 and later version.
1. Introduction of how to compile esp_iot_sdk based on the linux environment.
2. Download Espressif Official Flash download Tool
There are two ways to compile and download ESP8266 application (IOT_Demo or AT):
1) Support upgrade firmware(FW) through Wi-Fi, in this case, we store two FWs (user1 & user2) in flash, run one to download and upgrade the other one. More details of FOTA are in documentation 99C-ESP8266__OTA_Upgrade
2) Cannot upgrade firmware through Wi-Fi, in this case, FW can be in a larger size with the same flash, because only one FW stored in it.
AT first, no matter which way above, we need to copy files in folder "IOT_Demo" or "AT" to "\esp_iot_sdk\app" to complie!
Then here goes more details.
1) Support upgrade firmware through Wi-Fi (FOTA)
Compilation Steps:
(1) Run "./gen_misc_plus.sh 1" to generate user1.bin at "\esp_iot_sdk\bin\upgrade".
(2) Run "make clean" to clean up all previous compilation.
(3) Run "./gen_misc_plus.sh 2" to generate user2.bin at "\esp_iot_sdk\bin\upgrade".
Output:
user1.bin and user2.bin at "\esp_iot_sdk\bin\upgrade".
Download:
blank.bin; provided in SDK and to be burned to flash 0x7E000;
boot.bin, provided in SDK and to be burned to flash 0x00000;
user1.bin, compiled by the steps said above and to be burned to flash 0x01000;
PS.
(1) In general, we don't burn user2.bin to flash, but upgrade it through Wi-Fi.
(2) if you are using Espressif Cloud,
master_device_key.bin, applied for through Espressif server and to be burned to flash 0x3E000;
if you are using your own server, this master_device_key.bin is not needed.
NOTE: "AT" firmware always goes this FOTA way, because there is a command "AT+CIUPDATE" to upgrade AT FW through Wi-Fi.
2) CANNOT upgrade firmware through Wi-Fi
Compilation Steps:
(1) Run "./gen_misc.sh"
Output:
eagle.app.v6.flash.bin and eagle.app.v6.irom0text.bin at "\esp_iot_sdk\bin"
Download:
blank.bin; provided in SDK and to be burned to flash 0x7E000;
eagle.app.v6.flash.bin, compiled by the steps said above and to be burned to flash 0x00000;
eagle.app.v6.irom0text.bin, compiled by the steps said above and to be burned to flash 0x40000;
if you are using Espressif Cloud,
master_device_key.bin, applied for through Espressif server and to be burned to flash 0x3E000;
if you are using your own server, this master_device_key.bin is not needed.
NOTE: This FW cannot upgrade !

本文说明基于 Espressif BBS 的 编译环境
请下载使用Espressif Official Flash download Tool
ESP8266 的软件 (IOT_Demo 或 AT) 有两种编译及运行的方式:
1. 支持云端升级 (FOTA) : 详细说明可参考文档99C-ESP8266__OTA_Upgrade
这种方式其实是将 Flash 存储空间对半分，存放了两份软件 (user1 & user2) 在里面。
运行 user1 时下载并升级 user2，然后跳转到 user2 运行，下次就下载升级 user1。
2. 不支持云端升级
这种方式软件 bin size 可以大一些，因为 Flash 里仅放一份软件。
首先，无论哪种方式，编译时，需要先将“IOT_Demo” 或者 “AT”文件夹中的所有文件拷贝到路径 “\esp_iot_sdk\app” 下编译！
然后，我们来详细说说具体步骤。
1. 支持云端升级(FOTA)
编译指令如下：
(1) gen_misc_plus.sh 1，在路径“\esp_iot_sdk\bin\upgrade”下生成user1.bin；
(2) 执行make clean，清除之前的编译信息；
(3) gen_misc_plus.sh 2，在路径“\esp_iot_sdk\bin\upgrade”下生成user2.bin
生成：
user1.bin 和 user2.bin ，位于路径 "\esp_iot_sdk\bin\upgrade"
烧录到 Flash：
blank.bin，由Espressif 提供，烧录到0x7E000地址；
boot.bin，由Espressif 提供，烧录到0x00000地址；
user1.bin，如上编译生成，烧录到0x01000地址；
烧录补充.
(1) 一般不需要烧录 user2.bin 到 Flash; user2.bin 可通过云端升级。
(2) 如果您使用 Espressif 的云端服务器，
master_device_key.bin，向Espressif 云端服务器申请，烧录到0x3E000地址
如果您使用自己的服务器，则不需要烧录 master_device_key.bin
注意：只有这样编译烧录的软件才能云端升级！ AT 软件总是采用支持云端升级的方式编译烧录，因为 "AT+CIUPDATE" 指令实现软件云端升级功能。
2. 不支持云端升级
编译指令：
运行 "./gen_misc.sh"
生成：
eagle.app.v6.flash.bin 和 eagle.app.v6.irom0text.bin ，位于路径 "\esp_iot_sdk\bin"
烧录到 Flash：
blank.bin，由Espressif 提供，烧录到0x7E000地址；
eagle.app.v6.flash.bin，如上编译生成，烧录到0x00000地址；
eagle.app.v6.irom0text.bin，如上编译生成，烧录到0x40000地址；
如果您使用 Espressif 的云端服务器，
master_device_key.bin，向Espressif 云端服务器申请，烧录到0x3E000地址
如果您使用自己的服务器，则不需要烧录 master_device_key.bin
注意：这样编译烧录的软件，不能云端升级！
