arduino uno bootloading

Other Hardware 3rd Party Boards

Hi everyone,

I want to bootload some atmega 328 (TQFP package) with the arduino bootloader. I found out that my arduino isn't able to do that, due to some new autoreset functions.
=> http://arduino.cc/en/Tutorial/ArduinoISP
There is written that "A revision for this is in progress", has there been any revision so far?
Is there any other way to use the uno as a bootloader?

Thanks, Andy

The tutorial is wrong. The Arduino ISP sketch works fine on the Uno. You have to use a capacitor to disable auto-reset.

Thanks "Coding Badly" for the quick response.

I assume that I can put a 10uF cap between ground and the reset pin and it should have the same function as cutting the autoreset-solderbridge.
Am I right?
But why do I need to disable the autoreset function for bootloading?

I believe folks have stated that a 10 uF capacitor works.

Yes.

But why do I need to disable the autoreset function for bootloading?
