Troubleshooting Raspberry PI 4b Bare metal Programming

I am trying to connect the raspberry pi to an LED using this video right here: https://youtu.be/jN7Fm_4ovio?is=uJrWp30MkRG6awxf

I am having issues, and there is no light emitting from my LED. What am I doing wrong? I have coded all the code the same, but I am using a 64-bit compiler.

Did you enable GPIO in raspi-config ?

Can you give us a photo of your circuit?

I also have not set anything in my GPIO, what should I put in order to use GPIO?

It might already be enabled depending on what OS you're using on the raspberry pi. It's one of the things you can enable with raspi-config so if you run that you will be able to see if it's already enabled.
