Hello ROS community,

I am performing the firmware upload step for the turtlebot burger. I do the following steps:

export OPENCR_PORT=/dev/ttyACM0
export OPENCR_MODEL=burger
rm -rf ./opencr_update.tar.bz2
wget https://github.com/ROBOTIS-GIT/OpenCR-Binaries/raw/master/turtlebot3/ROS1/latest/opencr_update.tar.bz2 && tar -xvf opencr_update.tar.bz2 && cd ./opencr_update && ./update.sh $OPENCR_PORT $OPENCR_MODEL.opencr && cd ..

I get the results as shown on page https://emanual.robotis.com/docs/en/platform/turtlebot3/opencr_setup/#opencr-setup (OpenCR release is 1.2.5) I seems the

On https://emanual.robotis.com/docs/en/platform/turtlebot3/opencr_setup/#opencr-setup I read: Press and hold PUSH SW 1 for a few seconds to command the robot to move 30 centimeters (about 12 inches) forward. Press and hold PUSH SW 2 for a few seconds to command the robot to rotate 180 degrees in place.

I perform this action, however no positive result, the robot does not move or rotate.

However, I notice that Arduino led is blinking on an off.

To check if the OpenCR can find the motors, I uploaded the oFindDynamixel Firmware t and this gives following results: (In this case Arduino led is not blinking)

My questions:

Why is the Arduino led is blinking on an off. Do I need to configure the motors. Do I need to take another action, a configurations step
