First PCB design. Can't get bootloader on A328P-AU. Device signature = 0x000000

Development Tools Uploading

I can't manage to program a bootloader on my new prototype PCB board with an ATmega328P-AU chip. I have only soldered the microcontroller, bypass capacitors (C1 & C2), osciallator (X1) and reset 10K pulldown resistor (R8) along with the ICSP header.

Please see my designs on EasyEDA for reference: link

I'm using an Arduino Elegoo Mega 2560 R3 as my programmer on Arduino 1.8.9 and following instructions on the Arduino isp tutorial website link

I've tried making a second PCB to verify that I didn't have a bad chip and I'm getting the same outcome. I've swapped programming wires, checked the board for shorts and verified all continuity in the relevant connections without any luck.

Am I having this issue because I've not done a good job at applying bypass capacitors to the ATmega328P-AU in my design? I'm only using a single 1uF for all VCC/AVCC?

I'm a total rookie, any help would be appreciated. This is my first time soldering SMD components and my first time designing a PCB. See picture of my board below.

Nevermind, I was not connecting pin 10 on the programmer to reset on the target. Rookie mistake sorry.

For anyone reading this, when bootloading you can use the ICSP header of both devices by bridging +5,GND,MISO,MOSI,SCK but not RST. Each device has it's own reset, so the programmer (pin10) has to hold down the reset on the target. In hindsight this makes total sense, but hopefully this helps anyone troubleshooting the same issue.

Here is the output of my successful bootloader burn:
