Nightmare trying to burn bootloader onto ATMega328p

Post Body

Hey all,

So I'm trying to build an Arduino on a breadboard using an ATMega328P. It's a chip from Adafruit using their bootloader and I tried to just stick it into an old Uno but no luck so I figured it was some sort of bootloader issue, so I dug out my old Sparkfun AVR ISP shield.

Still no freaking luck. There is SO much contradicting information out there, from needing to change the baud rate, to changing the delay from 40 to 20, to "oh no that feature isn't in 2.X, use Sketch > Upload Using Programmer", and so much more.

I'm trying to burn the Uno bootloader onto an ATMega328P using an Arduino Uno with the AVR ISP Shield. Does anyone know the sketch I should be using? This is the error I'm getting:

Sketch uses 4354 bytes (13%) of program storage space. Maximum is 32256 bytes.
Global variables use 482 bytes (23%) of dynamic memory, leaving 1566 bytes for local variables. Maximum is 2048 bytes.

Failed uploading: uploading error: exit status 1

The power LED on the shield stay lit but none of the other LEDs do anything when trying to burn. Anyone have any ideas?
