About this repository

A new branching model is applied to this repository, which consists of a master branch and release branches.

1. Master branch

The master branch is an integration branch where bug fixes/features are gathered for compiling and functional testing.

2. Release branch

The release branch is where releases are maintained and hot fixes (with names like release/v2.x.x) are added. Please ensure that all your production-related work are tracked with the release branches.

With this new model, we can push out bug fixes more quickly and achieve simpler maintenance.

Roadmap

ESP8266_RTOS_SDK's framework is quite outdated and different from the current esp-idf and we are planning to migrate ESP8266_RTOS_SDK to esp-idf eventually after v2.0.0.

However, we will firstly provide a new version of ESP8266 SDK (ESP8266_RTOS_SDK v3.0), which shares the same framework with esp-idf (esp-idf style), as a work-around, because the multi-CPU architecture is not supported by esp-idf for the time being.

Actions to be taken for ESP8266_RTOS_SDK v3.0 include the following items:

  1. Modify the framework to esp-idf style
  2. Restructure some core libraries including Wi-Fi libraries and LibMain
  3. Update some third-party libraries including FreeRTOS, lwIP, mbed TLS, noPoll, libcoap, SPIFFS, cJSON, wolfSSL, etc.
  4. Update some drivers
  5. Others

Requirements

Both the xcc and gcc compilers can be used to compile the project. However, it is recommended that the gcc compiler be used.

For more information about the gcc compiler, please refer to esp-open-sdk.

Compiling

  1. Clone ESP8266_RTOS_SDK, i.e., to ~/ESP8266_RTOS_SDK.
    $git clone https://github.com/espressif/ESP8266_RTOS_SDK.git

  1. Modify gen_misc.sh or gen_misc.bat:

    • For Linux:
    $export SDK_PATH=~/ESP8266_RTOS_SDK
$export BIN_PATH=~/ESP8266_BIN
    • For Windows:
    set SDK_PATH=/c/ESP8266_RTOS_SDK
set BIN_PATH=/c/ESP8266_BIN

    You can use ESP8266_RTOS_SDK/examples/project_template to start your project, which can be copied anywhere, i.e., to ~/workspace/project_template.

  2. Generate bins:

    • For Linux:
    ./gen_misc.sh
    • For Windows:
    gen_misc.bat
