We have the IMU Razor 9DOF SEN-10736 connected to an FTDI Breakout Adapter http://www.dfrobot.com/wiki/index.php/F … :_DFR0065) which is in turn connected to the PC via a mini-usb cable.

When trying to upload Razor AHRS Firmware code https://dev.qu.tu-berlin.de/projects/sf … ahrs/files version 1.4.1 using the Arduino IDE (v. 0022 - we tried 1.0.3 but that didn’t work either), we get the following error message:

avrdude: stk500_getsync(): not in sync: resp=0x00

,

trying to hold the reset button, unplug, plug, hit upload and release the reset button

  • changing the usb cable

  • changing the COM port to COM8 on windows

Could you please help us

That message is perhaps one of the biggest pain points when it comes to programming the ATMEL range of devices, at least IMHO.

First thing to check is that you get a period power LED flash…that confirms the bootloader is OK. If you don’t get that, reflash the bootloader from your Arduino.
