Programmer is not responding, mac os X

Hi

I encounter some issues while trying to use my new arduino uno. Whenever I upload code to the board i get:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

First of all some information about the system: - PowerBook G4 running Mac OS 10.4 - Arduino UNO

I've been testing a lot and to check if the board isn't bad, i tried it on my parents PC (running Ubuntu). No problems there.

I have selected the correct board and port in the Arduino programm.

I have also tried the Loop Back Test (http://arduino.cc/forum/index.php/topic,67509.msg517462.html#msg517462), everthing I entered through the Serial Monitor was printed back.

What is causing this problem then?

Same thing is happening to me when I try to change the blink example to pin 8 and run it. Running 10.6.6 OSX. Hopefully someone knows the answer, I cannot find out whats wrong.

Try this Before click ulpload power the arduino with the reset pressed and the when you click upload release the reset. It help me a couple of times:) Just try

I don't think you have the same problem as i have, i can't even upload the standard blink example (without any changes)...

That's not working either. I still get the same error... Thanks for the reply though.

I'm still searching for possible solutions, and i have found this old post: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1287053635/0

which looks like the same problem, but there wasn't any answer posted... Member "Massimo Banzi" was going to look some information up, but nothing was posted.

I'm still hoping for possible solutions...

Perhaps this helps: the verbose mode:

Hi All,

I solved a problem in my case by downloading and installing old FDTM drivers: http://www.ftdichip.com/drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_2_18.dmg

Try to install FTDIUSBSerialDriver_10_4_10_5_10_6_10_7.mpkg, then re-start Arduino.

Works for me =)
