Hi, I have recently purchased a Arudino Duemilanove board and installed it on my compaq desktop running vista software . It worked perfectly . But a couple of days back the desktop was accidentally reformatted and original settings gone. I again downloaded the Arudino software and installed it . But unfortunately now I can't assign the com port 4 ( previously working) . Once I select the tools and try to select port it is frozen as COM 3. I tried to run the 'blink' program and getting the following error message. avrdude:stk500_get sync(): not in sync resp=0x00 arvdude:stk500_disable():protocol error,expect=0x14 resp=0x51
What may be the problem and how to solve the same? Thanks for your time.
