 Bigger Bigger  Smaller Smaller  Reset Reset

Specs
Macbook 10.4.11
new Arduino Uno atmel 328


I just got it and followed the getting started instrustion on this site(mind you i have nothing but the usb plugged in). Ive tried this with a several of the example sketches all with the same out come.

plug in the usb
open arduino 0021
open a example
compile/verify
upload

while Im uploading the Tx and Rx do flash a little bit (the rx flashes much more the the Tx)

then it says

"avrdude: stk500_getsync(): not in sync: resp=0x86"
a few seconds pass then
"avrdud: stk500_recv(): programmer is not responding"



I think this issue is often asked and im sorry I did search and none of the solutions seemed to work. ps does it matter which usb it is plugged into? also yes in tools its set to uno and tty.usbmodem

Thank you for your time and help


pps I also tried it on another macbook with exactly the same problem. And if this helps the L led flashes 4 times then stutters the flashes 4 times and stutters over and over when it is just plugged in

No I have already read through that post and was unable to resolve my problem with that solution. But this morning I used screen /dev/tty.usbmodem..... and it wrote 5 or 6 random ascii characters and thats all. I think it is connecting because the tx and rx leds do flash a bit and my mac does seem to see the arduino.

Did you manage to try with Windows?  Or maybe a Mac running 10.5 or 10.6?  That could help narrow down if it's the board or the computer.

I had the same problem, using an older mac with an arduino uno. I found that if I hold down the reset while plugging the usb cable into the arduino, with the computer already on that this solves the problem...

The pain is that you will have to do this every time you want to upload a new program, better than not working at all :-/

I have the same problem with the UNO.
 Running a G5 quatro powermac 10.4.11.

My mac recognizes the board as a modem as it should. And I can choose the right serial port (modem).
But if I start to upload it gets a sync or not responding problem.

I tried a few things and the only thing that sometimes works  is holding the reset button starting the upload. And release it when it's compiled. Or sometimes just push the reset button when it's compiled.
If I try it 15 times it will work only ones. A bit frustrating :-/. So there got to be a work around for this problem.

I thought the UNO would be even easier to use. But that ain't the truth for me. Luckily a have a few other previous gen boards lying around.

Bubba5656 let us know if you got the board running on windows 7?

I'm having the exact same problem but don't seem to be able to fix it regardless of when I push/hold reset.

Also, my led  (L) is already blinking straight out of the box...is that supposed to happen?

No. It should only blink when it has power connected to it. If yours was blinking when you took it out of the box, you should put it back in the box and return it.
