Setup ESP-IDF and CHIP Environment

Setting up IDF and CHIP environment is one time setup.

Setup ESP-IDF (Espressif IoT Development Framework)

Building the example application requires the use of the ESP-IDF and the xtensa-esp32-elf toolchain for ESP32 modules or the riscv-esp32-elf toolchain for ESP32C3 modules.

The VSCode devcontainer has these components pre-installed, so you can skip this step.

Install Prerequisites

Get IDF v4.4.2

  • Clone ESP-IDF v4.4.2 release

    $ git clone -b v4.4.2 --recursive https://github.com/espressif/esp-idf.git
    $ cd esp-idf
    $ ./install.sh
    
  • To update an existing esp-idf toolchain to v4.4.2:

    $ cd path/to/esp-idf
    $ git fetch origin
    $ git checkout v4.4.2
    $ git reset --hard origin/v4.4.2
    $ git submodule update --recursive --init
    $ git clean -fdx
    $ ./install.sh
    
  • For ESP32H2, please checkout tag v5.0-beta1, currently only lighting-app is supported on H2

    $ cd esp-idf
    $ git checkout v5.0-beta1
    $ git submodule update --init
    $ ./install.sh
    

Setup CHIP environment

Install Prerequisites

Prepare for building

Before running any other build command, the scripts/activate.sh environment setup script should be sourced at the top level. This script takes care of downloading GN, ninja, and setting up a Python environment with libraries used to build and test.

source scripts/activate.sh

If this script says the environment is out of date, it can be updated by running:

source scripts/bootstrap.sh

Once IDF and CHIP environment is set up, head over to application building and commissioning guide.
