I stripped my Ardupilot down to just the USB and a rc battery in order to try to upload Blink as a test. Any ideas on how to proceed. Photos attached. Running Windows XP USB on com3.I get:Problem uploadingBinary sketch size: 896 bytes (of a 30720 byte maximum)avrdude: stk500_getsync(): not in sync: resp=0x30avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
