Thank you for clarifying what have you done and what do you expect.
Before you start with teleop, please make sure, that after flashing the image, you have also flashed low-level firmware:
/home/husarion/flash_firmware.sh
Install teleop:
sudo apt install ros-dashing-teleop-twist-joy ros-dashing-joy
Then in separate terminal windows:
sudo MicroXRCEAgent serial --dev /dev/ttyS1 -b 500000
ros2 run dds_bridge dds_bridge
ros2 run joy joy_node
ros2 run teleop_twist_joy teleop_node
Regards,
Łukasz
