Topic: When will the new code be available to use an UNO as an ISP? (Read 752 times) previous topic - next topic

3 weeks ago I bought an Arduino UNO to use as an ISP board.

Now I read this on the Arduino site.

"NOTE: Currently, you cannot use an Arduino Uno as an ISP programmer because the optiboot bootloader does not support this sketch. A revision for this is in progress."

Because no target is mentioned I wonder when the new revision will be ready, I'm almost ready to start programming some Attiny chips, just waiting for some capacitors to arrive.

Coding Badly


That NOTE has never been true.  The Uno has always been capable of acting as programmer.

There was a time when it was necessary to physically disable autoreset to use the Uno.  This was the case with the optiboot HEX file that was shipped with 0022 (not sure about 0023) and flashed into many Uno boards' chips.

But the current optiboot code works fine without physically disabling autoreset.
