Description
I am trying to set a parameter server with a nucleo stm32f4 board , I already changed the values in colcon.meta (as said here https://micro.ros.org/docs/tutorials/programming_rcl_rclc/parameters/#callback) but the function is returning an error, although my program can continue rc = rclc_executor_spin(&executor); also returns RCL_RET_ERROR and goes out and I can not see the parameters of my micro ros app from the command ros2 param list .
I am using the FOXY distribution

Research direction
Start with the STM32CubeMX parameter-server setup and the colcon.meta changes described in the linked micro-ROS parameters tutorial. Reproduce the failure on the Nucleo STM32F4 with Foxy, then inspect why rclc_parameter_server_init_default and rclc_executor_spin return RCL_RET_ERROR. Done means the application runs successfully and its parameters appear in ros2 param list.
