Raspberry Pi: Write Your Own Operating System Step by Step (Udemy.com)

Good and straightforward course, it presents only the required information from the datasheets and user manuals, focusing the lectures on the topic. It worths the value for money, and sincerely, overcome my expectations.

The course is truly excellent and serves as a comprehensive starting point for anyone interested in learning how to write an operating system. It provides clear guidance and valuable insights, making it an ideal one-stop resource for beginners. Thank you, X-Bit Development, for creating such an informative and well-structured learning

I had taken some courses on operating systems development before and read some books on the subject. In the earlier courses I read (one here on Udemy also) it was hard to follow the idéas and you just code along - without understanding. In this course, the instructor explains the general idéas and all course coding content follows a logical thread, so if you follow along carefully, here you actually will understand how the code works, and hence, also how a simple operating system works, from the inside. However, I suggest you read at least one theory book on operating systems first, - to have the whole picture theoretical insight, before you start this course. It is also good if you have pretty solid knowledge in assembler and C language also. After, this course, is a very good one, to put all the theory you learnt into practise.

This course is somewhat unique on Udemy, which I love, but I do hope the creator can at least further update the content, including any mistakes, typos, and outdated parts.

Content is very good. Instructor moves at a brisk pace, without overly detail explanations, which is nice. The content will give you a chance to write a complete OS from start to finish. This will only serve as a starting point and provide a big pictuer view, which is really nice. The instructor has little bit of accent, which sometimes make it difficult to follow, but with English subtitle on, there is no issue. Great course, and thank you for developing it!

Very detailed and good course, it needs a bit more assembly knowledge than I expected.

I'm a high-level programmer but this is my first shot at low-level programming. Very interesting so far.

Challenging for people just learning about arm assembly, computer architecture and design. The instructor is extremely difficult to understand at times. This course essentially has you copying code. Decent introduction to bare metal programming where you use assembly and C to do low level configurations on system registers. However, not the best in my opinion. Definitely need a strong foundation regarding computer architecture, and you especially need understanding how the stack and memory works.

So far it's been understandable and clear, and I appreciate all the instructions for setting up one's environment. My big gripe is that the downloaded code is different in a few places than in the lectures, and comments in the code would have gone a long way to help retention and understanding

Brilliant course !! for all System Software Engineers working on ARMv8 architecture.
