wasm-micro-runtime as ESP-IDF component

You can build an ESP-IDF project with wasm-micro-runtime as a component:

• Make sure you have the ESP-IDF properly installed and setup

• In particular have the following paths set:

  • WAMR_PATH to point to your wasm-micro-runtime repository
  • IDF_PATH to point to your ESP-IDF
  • source $IDF_PATH/export.sh

• Create a new project, e.g.: idf.py create-project wamr-hello

• In the newly created project folder edit the CMakeList.txt:

  cmake_minimum_required(VERSION 3.5)
  
  include($ENV{IDF_PATH}/tools/cmake/project.cmake)
  
  set (COMPONENTS ${IDF_TARGET} main freertos esptool_py wamr)
  
  list(APPEND EXTRA_COMPONENT_DIRS "$ENV{WAMR_PATH}/build-scripts/esp-idf")
  
  project(wamr-hello)
  

• Develop your project in it's main component folder.

You can find an example here.

• Set target platform: idf.py set-target esp32c3
• Build: idf.py build
• Flash: idf.py flash
• Check the output: idf.py monitor
