I'm new to this, so please forgive me if this has been asked before and solved (I've tried searching).
I have an Arduino Ethernet, which I can program "blink" from Arduino 0022. I've tried Arduino 1.0 and I get a communication error: avrdude: stk500_getsync(): not in sync: resp=0x00
I have the board selected as Arduino Ethernet and the correct Com port (4). I'm programming via the USB to serial adapter. I've also tried via another PC, both of which run Windows 7.
Anyone come accross this before? I'd like to use the latest ethernet library, so I believe I need to get this working in 1.0...
I've had that before, I unplugged the cable from the Arduino so it lost power and disconnected from PC. Reattached and checked com port was correct within device manager and Arduino program. once I'd done that it worked like a charm.
If you want to use a FTDI cable to download your sketches on the Arduino Ethernet, please refer to this guide: Upgrade the Arduino Ethernet bootloader to the latest version
but you'll need a second arduino (ethernet).
follow the instructions on this page:
when finished. disconnect and reconnect your upgraded arduino with your USB2serial light cable and try to upload blink sketch to your upgraded Arduino (still selecting Arduino ethernet.
