Warning on bringup.

HI, I have a brand new TB3 and have followed all the instructions from the manual. I have also updated the OpenCR using the shell script in the manual. However, when I run roslaunch turtlebot3_bringup turtlebot3_robot.launch, the following warning shows up.

[ WARN] [1520881835.413400698]: Check OpenCR update and change your firmware!!

Everything on the bot seems to work just fine, however it is annoying to see these warn messages. Also, I am concerned that it will fillup the log files quickly.

Any ideas what might be going on here?

1. Update the OpenCR boot loader (ver 1.1.2) using the Arduino IDE http://emanual.robotis.com/docs/en/parts/controller/opencr10/#arduino-ide 6.1.7 Writing Bootloader(Linux)
2. Update the firmware using linux scipt http://emanual.robotis.com/docs/en/platform/turtlebot3/opencr_setup/#opencr-setup
3. Update packages and make

$ cd ~/catkin_ws/
$ rm build/ dev/
$ cd src
$ rm -rf turtlebot3/ turtlebot3_msgs/
$ git clone https://github.com/ROBOTIS-GIT/turtlebot3.git
$ git clone https://github.com/ROBOTIS-GIT/turtlebot3_msgs.git
$ cd ~/catkin_ws
$ catkin_make
$ source devel/setup.bash

Hope that helps…

I observed the same behavior as @mirwox . However, after I pull the code from git again, the problem seems to have gone away. I will close this for now. Thanks for your help everyone.
