How to create an OS from scratch

My dude. Your functions have exactly the same names as his. Copying it from a different tutorial based on James Molloy's tutorial does not make it any less James Molloy's code.

I started out with this tutorial: https://github.com/cfenollosa/os-tutorial. It doesn't get you too far but it explains the basics very well, so check it out. After that I looked up James Molloy's kernel tutorials (look it up on Google, it's all on a website). Be advised that he's got a bunch of errors and bugs in the tutorial, there is a whole page on it on the osdev wiki titled known bugs in the JamesM kernel all something like that, but it's still great and gets you pretty far. After that, I chose to develop a FAT32 driver on my own, I can link some sources or my own code for you as well, but it's really up to you to follow what you like. I also found a great youtube series (https://youtube.com/@poncho2364?feature=share9), check out his osdev series, he also has some cool stuff there. And as I said, good luck on your journey and you can ask me in a DM as well if you get stuck somewhere!

Yeah, I'm following cfenollosa's OS tutorial for guidance. You mentioned that you've seen the same code, with the same bug? What was the solution there?

hey, just in case you actually want to write an operating system, you should check out cfenollosa/os-tutorial: How to create an OS from scratch, it is an amazing tutorial that will get you from basic printing all the way to a command line interface!

You might be able to sink your teeth into something like this if you're interested in real os development, haven't got far myself but it's fun and you'll learn a lot https://github.com/cfenollosa/os-tutorial

So I made a 16-bit x86 toy OS in pure assembly. 3 months ago, I found a very fun tutorial on github that is about Operating system development. I read the first few chapter and from there I made a very simple, extensible (?) toy operating system that could run on hardware (yes, it is madness).

Last but not the least, learning by doing is fun so you can check out - raspberry-pi-os (writing an os from scratch) - https://github.com/s-matyukevich/raspberry-pi-os

CheesecakeOS for Raspberry Pi Volume 0: Booting, Processes, and Virtual Memory is the first in what I hope is a series of github markdown tutorials or volumes on bare-metal from-scratch operating system development.

I have dreamed of contributing to the Linux Kernel, but have yet to find the courage to jump in and do so. I started by attempting to read Understanding the Linux Kernel by Daniel Bovet and Marco Cesati, but found it was too advanced for me at the time. I found another text I credit with advancing my understanding, Computer Systems: A Programmer's Perspective by Randall Bryant and David O'Hallaron. I worked on the self-study labs from their book website, and found them to be a superb educational tool.

Further, then becoming interested in what creating an operating system actually means, I stumbled upon Sergey Matyukevich's Rasberry-Pi-OS github repo (https://github.com/s-matyukevich/raspberry-pi-os). I wanted to expand on his tutorial, for my own education, and, in the best case, for the benefit of others.

There are many ideas taken from Linux in the implementation, as when I didn't know how to proceed, that is the source I would consult. Though, I attempt to simplify and explain the details in the text. The implementation stops short of implementing or supporting a file system, the subject of the next volume.

Not familiar with this myself but aiming to start soon. Have found a nice youtube series for low level development on the RPi, not sure which version he uses, but reportedly it works for some on RPi 4. He also has a subreddit:

Here's one tutorial: https://github.com/s-matyukevich/raspberry-pi-os
