"ELF: not found error" running "micro_ros_setup build_firmware.sh" for nucleo_f767zi on Raspberry Pi

Issue template

• Hardware description: Raspberry Pi 4B 4gb (with BCM2711 soc) running Ubuntu server 22.04 (LTS) 64-bit
• RTOS: Free RTOS
• Installation type: ping pong example on nucleo_f767zi on ROS2 Humble latest release
• Version or commit hash: (default) humble

Steps to reproduce the issue

I followed the tutorial steps specified on the following page [https://micro.ros.org/docs/tutorials/core/first_application_rtos/freertos/]

I adjusted the line "ros2 run micro_ros_setup create_firmware_ws.sh freertos olimex-stm32-e407"
into "ros2 run micro_ros_setup create_firmware_ws.sh freertos nucleo_f767zi"

After that I entered the command "ros2 run micro_ros_setup configure_firmware.sh ping_pong --transport serial" according to the tutorial.

Errors occur at the buildstep "ros2 run micro_ros_setup build_firmware.sh"

Expected behavior

I expected that the build would happen without any problems. I followed the exact same steps within a docker container on my PC with an amd chipset without any problems. At the moment I try it on the arm infrastructure it does not work. I tried it in a docker image and with a local installation of ROS2.

Actual behavior

The following output is created showing an "ELF: not found" error:

Additional information

Any help will be greatly appreciated. Feel free to ask for additional information!

micro_ros_setup のエントリーポイントである build_firmware.sh と、生成された freertos_apps/microros_nucleo_f767zi_extensions/arm_toolchain.cmake から始めます。Raspberry Pi 上で arm-none-eabi-gcc 用の CMake コンパイラーテストを再現し、toolchain の実行可能ファイルが「ELF: not found」を出力する理由を調査します。nucleo_f767zi 用の ping_pong ファームウェアのビルドが完了すれば完了です。
