IMU Razor 9DOF SEN-10736 Arduino Upload Problem

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 done. Thank you.

We have tried various suggestions that we have read on forums such as:

  • 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

  • we are sure we are using the correct baud rate (57600); we even changed it to 57600 for the COM port

  • we are sure we chose the correct board (Arduino Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328) and serial port on Arduino

Could you please help us out?
