Can't upload to I/O

Hi!
I have looked for all the info in this page and many other forums trying to find a solution to my trouble.

I'm using Mac OS X Leopard 10.5.6 with a Arduino Duemilanove (ATMEGA328) with USB. I have installed all the drivers of the last package (0015) but when I try to execute the sample code to blink a LED (the one built-in in the pin 13) the program tells me this:

Problem uploading to board

Binary sketch size: 1000 bytes (of a 14336 byte maximum)

avrdude: stk500_getsync(): not in sync: resp=0x20
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x20

Can you help me?
Thank you a lot! :wink:

Have you selected the proper type of board from the pull-down menu?

Yes, I have selected the port and the board device (Duemilanove / Decimilia).

Thank you for your interest

try to uninstall the ftdi drivers and then install the latest drivers from the FTDI chip homepage (again).

i got the same trouble.
I tried all the possibility, but failed.... :-[

Do you notice any LED activity (on pin 13 for example) when you click UPLOAD?

Finally, I found my arduino board doesn't have ATMEGA chip.
Mine is the arduino board with Xbee Pro shield.....

Identify what you have based on this: http://arduino.cc/en/Main/Hardware

Is there an Arduino not based on an ATmega?

Did you try selecting "Arduino Duemilanove w/ ATmega328""?
