Help Uploading to Duemilanove on Macbook

Hello all,

I recently bought my first arduino, specifically the duemilanove. I have tried getting the processor to play nice with my Macbook running 10.5.6 using the Make book and the guide on the arduino website, but no luck so far. The green power light is on. I have installed the latest FTDI drivers (2.2.10), and have selected the dev.tty.usbserial-A6008dpO serial port in the program, as well as trying others when that didn't work. Everything I choose comes up with "Problem uploading to board." At the bottom, this is displayed: avrdude: stk500_getsync(): not in sync: resp=0x20 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xcc

I am really excited about getting to learn all about the arduino, and any help would be greatly appreciated!

Did you select the right type of Arduino board and CPU from the menu in the IDE?

I am having the same problem did you fix it?

Like Anachrocomputer said: check if you have selected the right board and mcu. If you have an atmega328 on your Arduino (the microcontroller) then you must select a board that uses the 328 (e.g. "Arduino w/ ATmega328")

After determining if you've selected the right board, another thing to try is a different serial port. If you have a "dev.cu.usbserial-A6008dpO" available, use that instead of the tty port.

Great, it worked! Thanks so much for the help. I had to switch over to the Duemilanove with the 328 and switched to the /cu serial and it worked like a champ. I appreciate the support!
