(RESOLVED) Verification issues ATmega328P burning bootloader (Nick Gammon)

Hi all,

I have an Arduino Nano V3 ATmega328P and have been trying to burn bootloader to Sanguino 1284P Board. I've tried various methods without luck. Have been stuck for days so any help greatly appreciated

I am currently trying to utilise the Nick Gammon method. The sketch uploads to the Arduino work fine.

Here is the output of ATmega_board_detector
