keep getting: avrdude:stk500_get sync():not in sync: resp=0.00

Trying to upload sketchs to Sparkfun Arduino pro using sparkfun FTDI basic breakout board.

I’ve gone thru the arduino troubleshooting suggestions.

Arduino Troubleshooting for avrdude: stk500_get sync():not in sync, etc

  1. Make sure you have the right item selected in the Tools > Board menu. yep :o

  2. check that the proper port is selected in the Tools > Serial Port (done so) :?

3)check if the drivers for your board are installed correctly is by opening the Tools > Serial Port menu in the Arduino software with the Arduino board connected to your computer (have done so, many times) :?

  1. Physical Connections

First make sure your board is on (the green LED is on) and connected to the computer. etc, etc (checked all)

Make sure there’s a bootloader burned on your Arduino board. To check, reset the board. The built-in L LED (which is connected to pin 13) should blink. If it doesn’t, there may not be a bootloader on your board. (yep, it blinks)

I’ve gone thru the whole troublshooting list, to no avail. And have followed suggestions by others who have had the same problem.

There seems to be no answer to this problem. Does anybody know what causes it?
:x :evil: potoole

I get that message when I try to upload while there is something else connected to the RX or TX pins. Unplug the wires on pins 0 - 1 before uploaading and it works ok.

I had a similar error with a pro mini. I was using USB power only during programming. As soon as I added a separate 5v source to the board, the problem went away.
