Auto-reset on NG

Hi!

I just soldered a 0.1uF capacitor to my Arduino NG (rev.c) as instructed in http://arduino.cc/en/Hacking/NGAutoReset.
After that, I started arduino IDE 0015 and changed my board type from NG or older w/168 to Diecimila... w/168. Tried to upload a program without pressing the reset but all that happened was that the rx led blinked three times and avrdude printed the following:

Binary sketch size: 976 bytes (of a 14336 byte maximum)

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

As I was trying with the blinking led example, I thought there could be a problem related to the pin 13, so I changed the example to use port 12 and uploaded the program after pressing reset (this is still working right), but no luck.

I even changed the capacitor thinking I might have burned it down while soldering, but I still have the same behavior.

¿Any hint? Thank you in advance.

Someone posted this information on libelium saying that the arduino.cc information is wrong. I'll try ASAP to change the capacitor.

I changed the capacitor to the 2 TOP pads and now auto-reset is working as expected (pretty cool and easy :slight_smile: )

The wrong page should be edited, but I can't do it...

lost a few hours on this one until i found fix on arduino blog. this page is still incorrect:

will post in bugs
