Nessuno ha ancora preso questa issue.

## Issue template

- Hardware description: Cortex R5F, ARM v7-R
- RTOS: FreeRTOS
- Installation type: micro_ros_setup
- Version or commit hash: humble

#### Steps to reproduce the issue
``
mkdir microros_ws && cd microros_ws
git clone -b humble https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup
rosdep update && rosdep install --from-paths src --ignore-src -y
colcon build
source install/local_setup.bash
ros2 run micro_ros_setup create_firmware_ws.sh generate_lib
touch my_custom_toolchain.cmake
touch my_custom_colcon.meta
ros2 run micro_ros_setup build_firmware.sh
``
#### Expected behavior
Firmware should build creating static libraries and required header files inside firmware/build/libmicroros.a and firmware/build/include
#### Actual behavior
[actual_output.txt.txt](https://github.com/micro-ROS/micro_ros_setup/files/14111855/actual_output.txt.txt)

#### Additional information
attaching my custom toolchain cmake and my custom colcon meta file
[my_custom_toolchain.cmake.txt](https://github.com/micro-ROS/micro_ros_setup/files/14111879/my_custom_toolchain.cmake.txt)
[my_custom_colcon.meta.txt](https://github.com/micro-ROS/micro_ros_setup/files/14111882/my_custom_colcon.meta.txt)
I tried removing the optimization flags in my_custom_toolchain.cmake file when I searched about it, but issue still remains

Inizia con build_firmware.sh e riproduci il colcon build utilizzando my_custom_toolchain.cmake e my_custom_colcon.meta; esamina actual_output.txt.txt per individuare il problema. Il lavoro è completato quando la build del firmware Cortex-R5F termina e produce firmware/build/libmicroros.a e firmware/build/include.
