Error building micro-ROS component on Raspberry Pi 4 with ESP32 #622

Description

I first tried installing micro_ros_setup. The build process was okay but when creating micro-ROS firmware by running the following command,

ros2 run micro_ros_setup create_firmware_ws.sh freertos esp32

I get the following error

Installing ESP-IDF tools
Installing tools: xtensa-esp32-elf, xtensa-esp32s2-elf, esp32ulp-elf, esp32s2ulp-elf, openocd-esp32
ERROR: tool xtensa-esp32-elf does not have versions compatible with platform linux-arm64
[ros2run]: Process exited with failure 1

It seems like micro_ros_setup is not compatible with raspberry pi 4.

So instead, I installed the ESP-IDF following this link. I was able to flash the hello_world example. The version I installed was v5.0 since it states that micro-ROS component has been tested in ESP-IDF v4.3, v4.4, and v5.0 with ESP32 shown here.

ubuntu@ubuntu:~$ idf.py --version
ESP-IDF v5.0.1-397-g3050ea656f

I wanted to ask

  1. Can micro_ros_setup work for raspberry pi 4? Or is it not compatible for linux-arm64?

  2. I think the Example section can be elaborated. In the example shown here, why isn't components directory created under the int32_publisher directory? Under the Usage section, it states to clone the repo directly in the components folder. Please correct me if I'm wrong.

    I copied the int32_publisher example from the micro_ros_espidf_component(link) into the home directory, created a components directory instead int32_publisher directory and then git cloned micro_ros_espidf_component inside it.

      ubuntu@ubuntu:~/int32_publisher/components$ ls
  micro_ros_espidf_component

    Running idf.py build command inside the int32_publisher directory, generates the error below

  Also, please check if the header file has been removed, renamed or relocated - refer to the migration guide for more information.

    I googled this error but didn't get anything helpful.

You can run your idf.py build directly into the example folder since it is prepared to find the micro-ROS component two folders above.

Copying the micro-ROS module into the components folder is the way for integrating it into your own IDF project because it is the default way of doing it: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html#example-project

If I run idf.py build directly into the example folder under micro_ros_espidf_component, I get the following error.

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

  idf.py build

Also is it possible to use Raspberry Pi 4 as the host and esp32 as the client? Everything worked well if I used my desktop but running into errors if I use Raspberry Pi 4. when I run create_firmware command,

ubuntu@ubuntu:~/uros_ws$ ros2 run micro_ros_setup create_firmware_ws.sh freertos esp32

I get the following error.

Regarding the first error, have you installed the required dependencies https://github.com/micro-ROS/micro_ros_espidf_component#dependencies ?

Regarding

It is not related to micro-ROS

Regarding the first error, have you installed the required dependencies https://github.com/micro-ROS/micro_ros_espidf_component#dependencies ? Yes, all the dependencies is installed Seems like others are also getting the same error

I followed the build and then ran `ros2 run micro_ros_setup component esp_idf` from the `uros_ws` directory. Tree shown below. And then tried building the `int32_publisher` example.

ubuntu@ubuntu:~/uros_ws$ tree -d -L 1 . ├── build ├── install ├── log ├── micro_ros_espidf_component └── src



So it is possible to use raspberry pi 4 with esp32?
