OS Development Resources
Comments recommend books, tutorials, wikis, and small open-source OS projects like xv6, MINIX, and XINU for learning to write kernels and operating systems from scratch.

Read the MINIX book. It's basically a walk-through (with source code) of entire operating system.
Hey man, I always wanted to write my own OS like xv6. Can I bother you?
osdev would help. It's not a book but a website.
Linux from scratch won't really help you. I'd say start by looking into writing drivers for Linux and looking at tiny OS examples for microcontrollers that can be run in emulators or cheap boards. Bare-metal projects are available for pi and beaglebone. You will absolutely have to do something like that at a minimum, so it's good to apply what you learned in your OS class to that stuff.
XINU OS worked for me. You can work with a beaglebone or a raspberry pi. There is a nice book for explaining every piece of the OS (IO, scheduler, memory management, etc.) and the source code is all there for you to tweak, browse, read or do whatever.HN discussion here: https://news.ycombinator.com/item?id=10643757
I'd recommend writing a toy operating system, there are many tutorials online. That will give you a good start. I wrote a small x86 kernel many years ago following online tutorials. It's great fun. You'll learn a lot from doing.Since you are at university ask around for a professor that teaches or is an expert in Operating Systems and seek his advice. That's why [s]he is there.
Pretty much what others said. You should read through https://wiki.osdev.org/Getting_Started and note that it will take a lot time if you decide to go for developing an OS.
That looks awesome! I did a little side project on rolling my own Unix kernel, highly recommend the guide! https://web.archive.org/web/20160301082842/http://www.jamesm...
That's it?While the point of this project is to go for developing a very small kernel, I afraid I can't recommend this as a way to "learn to write your first OS kernel".Particularly, this project has been fossilised for two years, (last commit was in 2018) with a single commit each year hardly qualifies as an updated tutorial for writing OS kernels.My first recommendation would be the "writing an OS in Rust" tutorials [0] and the xv6 tutorials [1].[0] <a
I recommend starting with something smaller.Here's something I put together some years ago - it's about 5,000 lines of code and supports a number of key Unix features. There's a PDF of lecture notes accompanying it.http://adelaideos.sourceforge.net/Once you've gone through this you'll be in a better position to tackle the Linux kernel and books on OS architecture.
