ArduPilot new build problem
Hi All,
I have just had my first ardupilot delivered with the ground station. I have built the ground station without any problems and programed it with my FTDI cable. I then went on to the arduPilot itself.
I have built it without any problems, however when I come to programming it it does not respond with the following errors:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I have checked the pin connections and they check out with a meter. I am assuming my FTDI cable and driver is fine as I programed the ground station. I have noticed that the reset button on the shield board does not have any effect on the ArduPilot and the LED's on the autopilot flash rapidly when powered. The reset button on the pilot itself does reset the board,I assumed the two would have the same effect. Are these two faults related? is this pointing to a corrupted bootloader?
Thanks for any help.
Richard
Its the reset button not having any effect

Richard,
How are you powering the Ardupilot? If you have powered it with a voltage greater than 5.5 vdc on the servo input/output pins then you may have damaged the Atmega chip.
The LEDs on the Ardupilot board flashing rapidly when the board is powered up is the Ardupilot executing the Sparkfun factory test program which indicates that the Atmega chip is functioning.
Did you activate the RST on close function in the COM port manager advanced settings?
The fact that the reset button does not appear to work is not encouraging.
Regards,
TCIII

Hi,
Sorry for the delay replying. All is now working (led checks only, waiting for xbee modules to arrive)
I checked the output from the ESC and it was at 5.77v. I have put a silicon diode in the +ve line and its now at 5.47v. The reset button works and it accepts programming. I have also activated the RST on the com port.
I suspect the programming is down the the RST line, while the Reset button function is down to the line voltage.
Many thanks for your help, your answer sorted it out.
I am now just waiting for my newly ordered ardu-imu and the xbee modules to arrive and I will be up and running.
