1. Introduction of how to compile esp_iot_sdk based on the linux environment.
2. Please using Espressif Official Flash download Tool
3. Compilation and downloading please refer to document 2A-ESP8266-SDK__Getting_Started_Guide
Compilation Steps:
(1)Run "./gen_misc.sh"
(2) Follow the tips and steps.
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!

编译与烧录的详细介绍，参考文档 2A-ESP8266-SDK__Getting_Started_Guide
编译步骤:
(1)运行 "./gen_misc.sh"
(2) 然后根据提示进行选择
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 !
Thanks for your interest in ESP8266 !

适用于 ESP8266_SDK_V0.9.4 及之前版本的 SDK
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！
希望本文对您有帮助。
