I am trying to get the rosserial_arduino tutorial to work (tutorial here).

The only change I made was to change the board type from "leonardo" to "OpenCR" since I want to use the Robotis OpenCR board.

The execution of catkin_make helloworld_firmware_hello gives me the following error:

CMake Error at /opt/ros/noetic/share/rosserial_arduino/arduino-cmake/cmake/Platform/Arduino.cmake:2073 (message):
  unparsed argument: Port;/dev/ttyACM0
Call Stack (most recent call first):
  /opt/ros/noetic/share/rosserial_arduino/arduino-cmake/cmake/Platform/Arduino.cmake:739 (error_for_unparsed)
  /opt/ros/noetic/share/rosserial_arduino/arduino-cmake/cmake/Platform/Arduino.cmake:459 (parse_generator_arguments)
  CMakeLists.txt:7 (generate_arduino_firmware)

Has anyone else encountered this problem before?

My ROS-noetic install is from yesterday, so everything should be up to date.

I think /dev/ttyACM0 does not exist.

Without connecting the Arduino to the machine running ROS, /dev/ttyACM0 will not appear. Also, depending on the Arduino, it may have a different name, such as /dev/ttyUSB0.

UPDATE

I watched the tutorial. I think you're making a typo.

Did you type the semicolon incorrectly?

Port;/dev/ttyACM0 -> PORT /dev/ttyACM0

The port is correct. When I plug in the board I the device /dev/ttyACM0 appears just as expected. While executing the catkin_make the board was plugged into my machine.

Can you let us know how did you try to run the node? The exact command. Also, as @miura says, check if you're passing the correct USB port as an argument.

I followed the instructions in the Tutorial and got the error as I executed catkin_make helloworld_firmware_hello. I named everything exactly as in the tutorial.
