I am trying to burn a bootloader onto an ATmega328P-AN using an Microcenter knock-off Arduino Uno R3 as my ISP for several days with no luck. The farthest I've gotten is writing and reading a few fuses prior to bootloader burn.
I have checked and rechecked the connections:
Uno ATmega328P-AN
GND GND
VCC VCC
MISO MISO
MOSI MOSI
SCK SCK
SS RESET
- I have a 2.2 uF cap from ground to RESET on my Uno, and a 16 MHz crystal with two 22 pF load caps to ground on my ATmega328P's XTAL pins.
- I have ArduinoISP loaded onto the Uno and my bootloader target is "Arduino Pro or Pro Mini", and my processor is set to "ATmega328P (5V 16MHz)".
I am using Arduino 1.8.9 on Windows 10.
Things I've tried:
Multiple boards and ATmega328P ICs - No difference.
Burning a bootloader to an Ebay Arduino Pro Mini knockoff, which worked, but there's no obvious electrical difference between this part and a raw ATmega328P. (Weirdly, the slight progress I made (setting some fuses - see below) was done by bypassing the DTR-cap-pullup reset path and running the ISP SS directly to the reset pin on the ATmega328P chip.)
Using Arduino IDE 1.0.x - No success.
Using a genuine Arduino Uno R1. No success.
Checking all the rails. I have a clean 5V and a clean ground. Unfortunately my lousy scope isn't picking up any of the 16 MHz oscillators, so I'm not sure what my clocks are up to.
In-circuit programming in a populated board with flying leads from the appropriate ICSP nodes. No success.
In-circuit programming with fresh board and just a power supply bypass cap, oscillator, load caps, and supply rails available.
Here's my Arduino IDE terminal output:

avrdude done. Thank you.
If I try to burn the bootloader again, I just get the "Device signature = 0x000000 (retrying)" messages, but no fuse write/read cycles.
I am really stumped at this point. Questions
Am I bricking my ATmega328P parts when the bootloading process is not successful?
What am I missing?
