Unable to Run on Arduino Mega 2560

[simonnarang]

Great Library...

Having some trouble getting it to work though.

Here is my CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.4)
set(CMAKE_TOOLCHAIN_FILE ${CMAKE_SOURCE_DIR}/cmake/ArduinoToolchain.cmake)
set(PROJECT_NAME Robotic_Arm)
project(${PROJECT_NAME})

set(${CMAKE_PROJECT_NAME}_BOARD mega)
set(${CMAKE_PROJECT_NAME}_PORT /dev/ttys0)

set(${CMAKE_PROJECT_NAME}_SKETCH Robotic_Arm.ino)
generate_arduino_firmware(${CMAKE_PROJECT_NAME})

I have a mega 2560 board, I am getting these errors when I have it plugged in and am running through CLion:

I had te same problem. You have to modify board.txt file in your arduino-1.X.X.X/hardware/arduino/avr/ folder.

Just add following (make backup of board.txt):

add to CMakeList.txt
set(${CMAKE_PROJECT_NAME}_BOARD mega2560)

and reload project
