We have the IMU Razor 9DOF SEN-10736 connected to an FTDI Breakout Adapter FTDI_Basic_Breakout_3.3_5V__SKU__DFR0065_-DFRobot 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-razor-9dof-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
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
