I am using an ATmega32u4 (adafruit circuit playground), and I am using the avr109 programmer (type butterfly). I am overriding the baud rate to be 115200.

This is the commandline argument that I am using(I used projectdir and Targetname here for ease of writing):
avrdude -v -p m32u4 -c avr109 -P COM5 -b 115200 -U

But, my problem is... when I upload my code... no matter which port I set to output, and make the ports high or low... nothing changes in my microcontroller (using asm) ... but when I code from arduino and upload my program... It works perfectly... Can you help me solve this problem?

WARNING: AVRdude is such a shit application, I'm so shocked so many people recommend it. Like it's literally so shit that I would be willing to buy software to compensate for it. Also what's pissing me off is how Atmel, who charges you an arm and a leg for their programming devices, just doesn't port Atmel Studio to Linux, IDE/software is flawless compared to software used in different tool-chains.
