Hi, I’m trying to make a DIY “Arduino” using AtMega32-16au.( https://ww1.microchip.com/downloads/en/DeviceDoc/doc2503.pdf ) I see it has 32 I/O pins, and I’m wondering bow does the Arduino boot loader recognize them. Any help is appreciated.

SOLVED IT! When I connected the oscillator to the oscilloscope, it wasn't oscillating and upon closer inspection of the board, I realized that I connected a capacitor between the ground and xtal1 pin. All I had to do was de-solder it and it worked!

Try adding a capacitor between RESET and GND on the programmer Arduino.
