[Solved] arduino pro mini 3.3v ATmega168 doesn't upload

Development Tools IDE 1.x
1

I'm working with windows 7 and arduino 0022.

After the advices of the trouble shooting section the error still remains.

On thd arduinoboard a green led is shining and a red led is blinking evey second.

On the usb_board two leds blink shortly twice if I reset the arduino board.

When I upload a red led is shortly blinking three times. After a certain time it blinks again.
The following message appears:

avrdude: stk500_getsync(): not in sync: resp=0x00
stk500_disable: protocol error, expect=0x14, resp=0x51

Windows did install its own driver and pretends that the best driver is installed.

baud=9600

Additional information:

The loop back test works fine:
Text is echoed with serial monitor.

But the upload still doesn't work...

I've tried also to exchange rx and tx.

Problem solved:

I've connected the reset line to vcc (following to a tutorial). That was wrong.
Now I've connected the reset line of the arduino to the reset line of the usb part
... and everything works like a charm.

... There was not much help in this forum.

There's not much to be seen on your photos, except for a mess of wires. A schematic would've been much better, hand-drawn is OK. Or even something like this:

USB board:        mini board:
----------        -----------
   RX       --->      RX
   TX       --->      TX

etc.

You were clever enough to figure it out yourself. But you didn't give sufficient information for providing you with an instant solution.

What tutorial did you use? If it wasn't on the arduino site, please don't blame us. Blame the author and send him a complaint, so he/she can fix the error it.
