micro-ROS agent stops on logger setup line

edit

I was following the micro-ros zephyr tutorial with discovery_l475_iot1 board and I have succesfully flashed a ping-pong demo with communication via serial usb on it. Anyway, when I start micro ros agent with command:

ros2 run micro_ros_agent micro_ros_agent serial --dev /dev/serial/by-id/usb-STMicroelectronics_STM32_STLink_066EFF514852897267173214-if02

its output looks like:

[1667242557.691466] info     | TermiosAgentLinux.cpp | init                     | running...             | fd: 3
[1667242557.692280] info     | Root.cpp           | set_verbose_level        | logger setup           | verbose_level: 4

unplug, then plug microcontroller doesn't work and resetting it with the button doesn't work as well.

I use ROS2 Humble on Ubuntu 22.04 server with kernel:

Linux ubuntu 5.15.39-rt42-raspi #1 SMP PREEMPT_RT Sat Jul 16 08:34:58 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux
