Hello,
We currently have a ESP32-DevKitC-32D-F board and are trying to use Amazon FreeRTOS to connect it to Amazon IoT Core. After following this guide https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_espressif.html we have reached the “Flash and Run Amazon FreeRTOS” section but have run into a “CMake Error at CMakeLists.txt: 34 (message) Board is not supported: vendor.board” when trying to flash it.

We are trying to find out if we have to use a strict ESP32-DevKitC board or our board should work and we have made a mistake in our configurations.

Thanks for any help!

Which OS are you using? I am able to use the following commands on Ubuntu 18.04:


git clone git@github.com:aws/amazon-freertos.git
cd amazon-freertos/
cmake -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=xtensa-esp32 -S . -B build
cd build/
make -j4
cd ..
sudo python ./vendors/espressif/esp-idf/tools/idf.py erase_flash flash monitor -p /dev/ttyUSB0 -B build

Which version of ESP32 toolchain are you using? You can check that using the following command:


xtensa-esp32-elf-gcc --version

Also, would you please share the output of all the above commands (including cmake and make)?

Thanks.

Hi TianGang,

We have been successfully able to complete the build now but there is still a problem flashing (described below).

Hi,

If you’re running on Windows, you need to explicitly specify a “build generator” (a concept in CMake) because on Windows CMake defaults to Visual Studio IDE and its msvc compiler. This is documented in the “Build Amazon FreeRTOS on Windows” section in the getting started guide that you were following, https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_espressif.html#build-and-run-example-espressif

Here’s the CMake command to run,

cmake -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=xtensa-esp32 -GNinja -S . -B your-build-directory

Note that there’s a -GNinja in the command. Let me know if this helps.

Thanks

From the last line in your output, looks like ESP-IDF is still using the visual studio generator somehow. Did you delete the build directory before you rerun the CMake command? If it’s still not working, you can also try explicitly appending the generator to idf.py,

python ./vendors/espressif/esp-idf/tools/idf.py flash -B build -G Ninja

To check all the available options from idf.py, run with --help,

python ./vendors/espressif/esp-idf/tools/idf.py --help

Hi,

Just noticed one thing from your previous reply, I think you’re using different “build directory” for build and flash (FYI, the build directory can be any directory on your file system, you pass that to CMake and let it generate the build files). For build, because you executed exactly same command I posted, it’s building the binaries in “your-build-directory” folder, however, when you try to run flash command, it’s looking for the binaries in the “build” folder.

So basically in the 2 commands below, “<build_dir>” needs to be the same,


cmake -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=xtensa-esp32 -GNinja -S . -B <build_dir>
python ./vendors/espressif/esp-idf/tools/idf.py flash -B <build_dir>

Make sure you execute the above command from a clean source tree, and the build directories matches.

We have spent the weekend trying to find a solution to this error but have had no luck so far.

Thanks for the help.

Hi,

You’re using the xtensa-esp32-elf-gcc version 8.2, it’s not supported as of now,

Please check the “Set Up Your Development Environment” section in our getting started doc, https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_espressif.html#setup-env-esspressif. The toolchain link as documented in the doc should be https://docs.espressif.com/projects/esp-idf/en/v3.1.5/get-started-cmake/windows-setup.html

Hi All,

This seemed to be the fix to our problem.

We are now able to build, erase, and flash!

Thank you for all your help!

It was greatly appreciated!!

Hi all,
I’m starting with Amazon FreeRTOS and ESP32. Recently I built and ran demo successfully for DevKitC board. But I got a small question.
I see Gaurav-Aggarwal-AWS provided short summary of build steps here and it causes the same question for me. It contains line:

cmake -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=...

but the board in topic is DevKitC, not WROOVER and cmake have separate DBOARD parameter value “esp32_devkitc”.
So, the question: is it correct to use -DBOARD=esp32_wrover_kit for ESP32 DevKitC board? Or should we use -DBOARD=esp32_devkitc instead?

Hey vlad-hid,

For the cmake generation command you can use either esp32_devkitc or esp32_wrover_kit, they both map to the same code.
