Thank you very much.

Which release of micro-ROS are you targeting? Galactic or Foxy?

[AIxWall]

foxy.I've tried many times and it's the same error

[pablogs9]

Check this patch: #365

[AIxWall]

thanks.the error message disappears. it should download some packages from github,e.g. ament/ament_cmake,but it didn`t,i wonder why.
also
when Configuring the firmware with the following command:
$ros2 run micro_ros_setup configure_firmware.sh ping_pong --transport udp --ip 127.0.0.1 --port 8888
the following error appears:
~/workspace/microros_ws_zephyr/firmware/zephyr_apps/apps: No such file or directory
