[turtlebot3_ros2] No Firware working with motor test

[Gredin67]

I've tried to flash OpenCR with all possible ways :

• ROS1 or ROS 2 pre-built binaries (https://github.com/ROBOTIS-GIT/OpenCR-Binaries/tree/master/turtlebot3)
• noetic or ros2 pre-built
• Arduino IDE flashing : examples>TurtleBot3>turtlebot3_waffle or examples>TurtleBot3 ROS2>turtlebot3_waflle

No way to get the wheels rotating with the test buttons. Note the the motors get powered on with some Firmware (brakes locked), but no rotation.

I also checked with DynamixelWizard2 that the baud rate (1M) and the ID were correctly configured.

How can I further debug what is happening ? Hardware issue ? Firmware issue ? Other ?

Note also that my ultimate goal is to get turtlebot+openmanipulator working with Humble. OpenManipulator is working through OpenCR with usb_dxl, but turtlebot3 waffle pi alone is not.
