What is Reddit's opinion of Linux Driver Development for Embedded Processors - Second Edition: Learn to develop Linux embedded drivers with kernel 4.9 LTS?

From 3.5 billion Reddit comments

i was figuring things my self. if setting up the make / linker you could just use PlatfromIO. before moving on to the native builds.

remember there is no start guide for zyphr. you need to study linux device drivers first!!

have you given this book a read? thoughts? from a description, it seems like it's fairly practical as in it's got examples to actually interface with different HW which I like the most about it

When you say old, you're referring to the APIs in particular? I'm a bit puzzled as to whether I should still go for it or instead get another book that focuses on a relatively newer kernel like this one perhaps?

So basically you're suggesting not to delve into the API implementation since they have been changed? I was thinking of just getting straight to this book

Might as well get a book on a relatively newer kernel -- something like this perhaps...

It's not just the code but I wanna get some understanding of the theory as well which I feel I'd find better in a book.

How does this look? Seems to have practical examples plus theory

The link you gave just above my comment.

Bootlin course materials are amazing IMO. Also using the book : Embedded Linux driver development is a pretty good way to start writing device drivers.
