Dear all,
I have tried several options, but it seems that my arduino uno is not able to "talk" with blank atmega for burning the bootloader.
I don't understand, I can upload sketches to my Uno and are working fine.
I can use my Uno to upload sketches to a ATmega328-PU which I already have and has the bootloader already on it by:
- Connect Uno to the board:

- Edit avrdude.conf (located in \hardware\tools\avr\etc) by going to the Atmega328P entry and then replacing "0x1e 0x95 0x0F" with "0x1e 0x95 0x14".
- Open sketch to be uploaded to the arduino on the board
- File > Upload Using Programmer
But I'm not able to burn bootloaders...
Does anyone have suggestions or other tests I can do?
Thank you,
dk
EDIT:
Last try: I uploaded Nick Gammon's ISP sketch on the ATmega328-PU I have via my Uno. Connected via FTDI as shown here:

and than connected it to by blank ATmega328-PU but it always stops at "Attempting to enter programming mode ..."

same thing using an ATmega168-20PU...
