System Info

lerobot's low cost hardware configuration: Waveshare Serial Bus Servo Driver Board will brick the servo when update the firmware of servo

Information

• One of the scripts in the examples/ folder of LeRobot
• My own task or dataset (give details below)

Reproduction

https://forum.robotis.com/t/firmware-transfer-failed-on-new-motor/5819

Expected behavior

The readme (https://github.com/huggingface/lerobot/blob/main/examples/7_get_started_with_real_robot.md)
should not suggest updating firmware in https://github.com/jess-moss/koch-v1-1, the servo board will brick the servo.

@sergesteban I fixed it by using by the U2D2 and doing a firmware recovery with the wizard.
