The minimal breadboard Duino article has chip ID and Nick's programming software that accepts many ID's.Here's a page with what you may want directly:
Gammon Forum : Electronics : Microprocessors : Atmega bootloader programmer
Hi,
I went through Nick Gammon's forum (Gammon Forum : Electronics : Microprocessors : Atmega bootloader programmer) and am so happy to tell you that i could detect the ATmega328PB's signature correctly as well as could upload the bootloader onto the chip. Thank you for guiding me!
I think the issue was with the internal clock as somehow it couldn't detect the chip and i was stuck. On the forum, i found an alternative to it. Using the sketch Atmega_Board_Programmer, i got an alternative of getting a 8MHz clock signal on pin D9 of the programming board.
Now, i can move forward to programming my board
