We've just received our arduimu v2+, we've got problems to upload the arduino sketch to it.

  • we're using the FTDI cable from DIYDrones shop, with the right colors at the right place (black near GPS).
  • when uploading to the board, the code is compiling in Arduino, and after a while, we get this errror (on mac):
avrdude: stk500_recv(): programmer is not responding
: stk500_recv(): programmer is not responding
  • on windows, we've got this error:
avrdude: stk500_getsync(): not in sync: resp=0x00
: stk500_disable(): protocol error, expect=0x14, resp=0x51
  • the leds blink like there is a reset occuring, and the code seems to start just after (red light switching on on movement).
  • I've tried the reset technic, by pressing the reset button at various intervals after the code has compiled, from the Ardupilot FTDI Firmware Programming video.

Would you have some advices for us to upload arduimu firmware?

Thanks a lot,

Alex & Marco

Hi Dhiraj,

We've solved the problem by using the FTDI Usb Explorer board from Sparkfun, maybe the FTDI cable was not working properly, we need to test with another USB FTDI cable to be sure on this point.

Good luck,

thanks.for your help alex
Hi Alex
Can you please be specific as to which exact usb explorer board you used.
Did you use the 5V version or the 3.3V? Your help would be greatly appreciated.

I have the same problem. Strangely the cable seems to work fine to program the Ardupilot.

Same with me. Any ideas? I'm using 5V version of cable.
