[BUG] idf.py monitor will error occur

[misupopo]

• Hardware board: ESP32-DevKitC
• IDE used: clion
• Operating System: MacOS Monterey 12.3.1
• Code version: 202203.00

I followed the steps of the AWS docs to build. However, when I run "idf.py monitor", I get the following error.

Is this a bug? I proceeded as per the documentation.

■idf.py monitor error

CMake Error at freertos/vendors/espressif/esp-idf/components/esp32/project_include.cmake:21 (message):
  Internal error, toolchain has not been set correctly by project (or an
  invalid CMakeCache.txt file has been generated somehow)
Call Stack (most recent call first):
  freertos/vendors/espressif/esp-idf/tools/cmake/build.cmake:312 (include)
  freertos/vendors/espressif/esp-idf/tools/cmake/build.cmake:457 (__build_process_project_includes)
  freertos/vendors/espressif/boards/esp32/CMakeLists.txt:591 (idf_build_process)
  freertos/CMakeLists.txt:78 (include)

The actual procedure I executed is as follows.

• AWS Console GUI
  • AWS Full access to IAM.
• mac terminal
  • brew install cmake ninja dfu-util
  • create empty project directory（mkdir ./someProject）
  • cd ./someProject
  • git init
  • git clone https://github.com/aws/amazon-freertos.git --recurse-submodules
  • git submodule update --init --recursive
  • rename amazon-freertos to freertos
  • cd freertos
  • vendors/espressif/esp-idf/install.sh
  • source vendors/espressif/esp-idf/export.sh
  • moved current directory and create src drectory and CMakeLists.txt
  • cmake -S . -B build-directory -DCMAKE_TOOLCHAIN_FILE=freertos/tools/cmake/toolchains/xtensa-esp32.cmake -GNinja & cmake --build build-directory & cmake --build build-directory --target flash
  • cmake --build build-directory
  • cmake --build build-directory --target flash
  • idf.py monitory ← that error will occur

Hi @misupopo,

For using AFR in custom CMake project, please check this repository: https://github.com/shubhamkulkarni97/amazon-freertos-examples

Thank you very much for your help. It looks like it will be very helpful.

I flushed to ESP32. it was success.
