How to compile an AWS FreeRTOS ESP32 project using VS Code?

Hello to all the FreeRTOS and AWS community. Congratulations for this great work.

Kindly, I am asking for support about how to compile AWS FreeRTOS ESP32 projects in VS Code.

I will explain first, all the details about how I’ve compiled, and successfully tested some demos using the ESP-IDF Command Prompt v4.2 of IDF, with the toolchain esp-idf-tools-setup-2.3.exe, Python 3.8.3, git version 2.30.1.windows.1 on Windows 7 Ultimate.

I have been able to compile via ESP-IDF Command Prompt examples from the AWS FreeRTOS Console, and freertos-aws-reference-integrations from Github.
In both cases, the version is Version 202012.00 with crosstool-ng-1.22.0-80-g6c4433a used in 5.2.0

The freertos-aws-reference-integrations for Espressif (and other vendors) on Github

The unzipped folder I place it on C:\esp-idf-v4.2 just for consistency, I keep it as my root folder :C:\esp-idf-v4.2\FreeRTOS

I modified one line of code on C:/users/username/.espressif/_idf_cmd_init.bat which makes possible to move back and forth to use the native idf v4.2 examples and demos from FreeRTOS just commenting that line.

For path configuration, I used the default one which is made from the esp-idf-tools-setup-2.3.exe installation.

And for FreeRTOS, I used the install.bat and export.bat present on C:\esp-idf-v4.2\FreeRTOS\vendors\espressif\esp-idf\install.bat and C:\esp-idf-v4.2\FreeRTOS\vendors\espressif\esp-idf\export

In order to execute the coreMQTT and ota examples, I double clicked the ESP-IDF Command Prompt cmd.exe (generated from toolchain installation), changed directories to FreeRTOS cd FreeRTOS and issued the next commands:

  1. coreMQTT demo

cmake -DVENDOR=espressif -DBOARD=esp32_devkitc -DCOMPILER=xtensa-esp32 -GNinja -S . -B demos/coreMQTT/build

python C:/esp-idf-v4.2/FreeRTOS/vendors/espressif/esp-idf/tools/idf.py build -B demos/coreMQTT/build

python C:/esp-idf-v4.2/FreeRTOS/vendors/espressif/esp-idf/tools/idf.py erase_flash flash monitor -p COM4 demos/coreMQTT/build

  1. ota demo
    cmake -DVENDOR=espressif -DBOARD=esp32_devkitc -DCOMPILER=xtensa-esp32 -GNinja -S . -B demos/ota/build

python C:/esp-idf-v4.2/FreeRTOS/vendors/espressif/esp-idf/tools/idf.py build -B demos/ota/build

python C:/esp-idf-v4.2/FreeRTOS/vendors/espressif/esp-idf/tools/idf.py erase_flash flash monitor -p COM4 -B demos/ota/build

All working quite good so far :laughing:

I want to achieve all that I did for AWS FreeRTOS on cli using VS code. I tested and flashed the simple_sniffer from IDF 4.2 example using VS code and worked flawlessly.

My issue is trying to do the same with any of the examples on demos folder on FreeRTOS. Probably I am missing some cross-compiling configurations? Some path issues?

My working configurations for VS code are here (the one I used for the simple_sniffer example)

The failing configurations for AWS FreeRTOS ESP32 for VS code are here.

I even checked the link using-visual-studio-code-for-freertos-development.html, but still I can’t make it work.

I would really appreciate your support on this. Thanks in advance.
