stk500v2 checksum
I just got the RAMPS 1.4 with the ATmega 2560. I tried to flash the Merlin script but it fails and gives me the message 'stk500v2 checksum...'. I tried all kinds of settings and different cables plugged into different USB port but always with the same results. I googled the message and found no solution.

Please select all the files(Ctrl+A) and drag them into Arduino IDE.

Re: stk500v2 checksum
I'm not sure what you mean by this. The error message I'm talking about comes from the Arduino IDE. I'm using the latest, arduino 1.6.1. I configured the Marling Configuration.h and compiled all the Marlin files in the Arduino IDE and it compiled OK. When I tried to write it to the ATmega the message came up.
So, what files should I select and drag to the Arduino IDE?

Re: stk500v2 checksum
You said "complied ok" , So did you choose correct board type(Arduino Mega2560 or Mega ADK) and serial port before uploading? Please check.

zhangxueyou, thanks for trying to help me!
I have chosen the correct board. As for the port, when I plug in the USB cord and connect the ATmega it automatically chooses the COM4. I can't change it to 'Serial Ports'.

Re: stk500v2 checksum
I had bought a second ATmega 2560 board to see if the one I got from GEtech is defective or not. The new board arrived and it gave me the same problem. That meant that the problem is my computer and not the boards. My main computer runs with Windows 10 tech preview. I have an old computer with Windows XP. I tried both board on it and it loaded the sketch to both of them fine. They are both now running with no problem.
Problem Solved!
