Firmware upload error

Im getting this error on my new i3 build when uploading firmware via Arduino IDE uploader 1.6.8. Any idea what this is? The board led flashes when uploading but it hangs after a while:

avrdude: stk500v2_recv(): checksum error
avrdude: stk500v2_recv(): checksum error
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer

I haven't tried a new cord. The cord worked on my CNC controller but I will try a different one. No lamps or weird stuff around.

This is the latest error:

avrdude: stk500v2_recv(): checksum error
avrdude: verification error, first mismatch at byte 0x074e
0x50 != 0x00
avrdude: verification error; content mismatch

I tried a new cord but the same error occurred. I have tried the blink test and that uploads fine and works.

Got it to work!

I read a few posts and I tried a bunch of random ideas. One or some of these fixed it.
- I turned off the power supply to the Arduino and just used the USB
- Pressed reset while uploading which generated an error
- Next I switchd the processor from Mega 2560 to 1280 which also generated an error
- I finally switched it back to 2560 and reuploaded which worked..

I have no idea why this worked but it did.

It's not working anymore.

Everytime I upload it timesout. I can see the lights flashing on the board then it just stops and hangs for a long time and finally the software catches up and gives a 20 lines of errors like this:

remove the ramps, just try uploading to the bare mega powered over the usb cable.

re 1280 vs 2560 you need to select the correct board in the ardunio IDE , the 1280 has a different upload baud rate than the 2560 (with standard boot loaders)

I couldn't get it to work with the shield off either. I ended up switching from a laptop to desktop and it worked instantly. I am not sure why that's the case but I guess I have to use a different machine to upload.

Edit: Turned out I messed up downloaded the nightly build. The stable release works fine on both computers. Sorry for any wasted time. Thanks for helping!

Heyhey and good evening,
I actually have a similar problem, where first I thought it was a problem with the board, or rather, the bootloader. Now, after ordering and sending back two more MEGA 2560s, and finally trying instead to upload using my laptop (instead of my desktop), I can verify that the problem is NOT the board but the USB-connection. This baffles me, as it was working before, but now I get the same exact error:

avrdude: stk500v2_recv(): checksum error

So, my setup is this:
I have two MEGA 2560-boards. Both of them will run Repetier firmware, but I fried the USB-capability on the first one that I got - it still works as a printer, but I can't upload new firmware to it and have to print using an SD-card. That is last weeks problem though. I guess I could try using the second board as an AVR-programmer to replace the bootloader, already looked up how. I don't have high hopes here though.
I have two computers running Windows 10 available to me. Both of them have the Arduino 1.6.8 version installed, and before this USB-trouble started, both were able to upload firmware to the MEGA. Now though, only the laptop will succeed in uploading Repetier though, while the desktop will only upload for example the Blink-sketch.
Arduino-drivers and -software are installed and reinstalled, COM-ports are reset, the desktop was restarted several times. I get the MEGA on COM port 5 in the device manager, and it also disappears when I disconnect it. The fact that the Blink-sketch is uploading and that I can connect to the board with Repetier-Host show that the setup on the desktop should be working. But then - since Amazon brought me three boards this week, two of which I sent back after experiencing the same problem, I also exclude a hardware error.
I tried switched USB-ports, connecting to the front- and back-ports of my desktop, and also using two different chords, both of which work on the laptop.
any ideas what I could still try?

Thanks in advance!



EDIT: SOLVED!
Your solution was my solution - even though 1.6.8 is the most current "stable" version to download from their website, I reverted to 1.6.7 and it works without a hitch. Thanks!
I'll leave this here for future generations.
