I recently purchased an Arduino Duemilanove starter kit at the Maker Faire and cannot get the first program ( Blink ) to work. I installed the software and setup in my Netbook with Windows operating system and got stuck in an endless loop with the TX light blinking when I tried to perform the upload to I/O board.
Today at work I tried instalkling and running it on my Windows XP PC and got the following messages when performing the upload to I/O board:
AVRdude: STK500_getSYNC():
not in sync:resp=0x00
make sure you have installed the USB driver and that you have the correct port selected in the Arduino IDE. The troubleshooting guide has more details on this: http://arduino.cc/en/Guide/Troubleshooting
I got that error when I had the wrong board selected. Make sure you select the Duemilanove w/ 328, and not the Duemilanove w/ 168. Click to change it. (This assumes your new board is a 328 - it should have a sticker saying so if it is).
