Diecimila with strange behaviour

Hi, I am helping a friend hookup and program an Arduino Diecimila. Apparently he just bought this board and it has never been used (right out of the box). I installed the FTDI driver and the Arduino IDE. When I plug the Diecimila to USB, the power led is on correctly and the USB prober on my Mac recognizes the USB device and reads all the info on the board correctly (vendorId. productId, etc.). BUT the led labeld L (right above TX) starts to blink continuously. And when I try to load a skech from the IDE I get the following error messages:

avrdude: stk500_getsync(): not in sync: resp=0x30 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Any ideas what could be wrong?

Thanks in advance for any help.

The blinking behaviour is fine - it is SUPPOSED to do that to tell you it's alive.

In regards to the uploading error, do you have the correct serial port and correct type of board selected in the Tools menu?

Great!!

Thanks for the help and sorry for newbiesh question.

I just had to select /dev/tty.usbserial-A4000Qgj

and it all worked fine. Now back to the examples

hanks again.
