Folks,

 

I just watched this video...

 

  https://www.youtube.com/watch?v=...

 

I thought there was a capacitor on the reset line of the Arduino UNO that prevented debugWire from working for step debug? Am I missing something new?

 

I remember seeing this excellent posting on the matter...

Comments welcome.

 

Best,

Yes, of course there is a capacitor.
That is why you open the RESET-EN solder bridge. Disable the BOOTRST fuse during the debug phase.
When complete, use the Arduino IDE to "Burn Bootloader". However good you may be, you are bound to forget something if you try restoring by hand. The IDE does flash, fuses AND lockbits.

So we must assume then, for the video he had modified the board, by opening the RESET-EN solder bridge.  Been nice to include that fact in the comment section.

 

Note the connecting board that makes the change over to the 6 pin ISP connector, and the right angle header out of the Arduino Board.

 

All in all a nice rig.
