I try to program my Arduino with the "Blink" exemple to test it. The Rx LED blinks (and not the Tx) 3 times and I obtain the "avrdude: stk500_getsync(): not in sync: resp=0x00" error when I try to send a program. The On LED is green and the "L9" LED is green too, not blinking : is it meaning that I have no bootloader on the Arduino ? (In that case how can I load one in my Ethernet Arduino ?)
This error appears under my win XP 32bits computer or with my win 7 64bits computer. I have no Bluetooth peripherals on both computers. I have the Ethernet version of the Arduino.
The Arduino pass the Loop-Back test, so I don't see what to do ...
