help making custom rapsberry pi os system

Hey, I’m here for one purpose and one purpose only I’m trying to make my own raspberry pi custom OS system. This OS system would be a program kind of like chat GPT I mainly focus on machine learning type of things and be more of an assistant. All I basically need help with is the overall necessity such as a kernel8.img, boot loader, main, and etc so I could at least put the SD card in and it would just at least execute the program. if you could help me with sending messages and a couple of other things like installing programs, I think that’s all I need for the most part I think after that I could catch on.  i’m aware that the raspberry pi does not have the power to obviously run major servers in the future. I might consider applying add-ons to the raspberry pi or maybe something else. But for now I would really love some help developing a custom raspberry pi operating system. Also, would like to mention that this custom OS I would really love to run possibly tensor flow models if you’re able to provide any other resources on this, I would greatly appreciate it . Thank you

You'll need to learn ARM assembly

and some low level langs

then you'll need to write a bootloader

for your kernel

Any tutorials

Or

Books

Not really

There is this but it's mainly for x86 https://wiki.osdev.org/Expanded_Main_Page

Do you know how to make a raspberry pi OS system?

I've made an x86 OS before

but that won't run on a pi

You know anyone who can help

there arent that much companys with their own OS

Email?

Yea I want to make one

And I’ve tired by watching a tutorial

But can’t boot it

Like I’m pretty sure the program is being executed

Little bit of C

No assembly

If you have any tutorials or guides that would be nice

well then you are not ready for your own OS according to previous website

So what should i do

Coming from someone who did it, it's not worth it

thats my point

I was mainly going to use it for Machine learning programs and maybe flight navigation with rockets

just use lightweight linux?

Flight navigation is better suited to a microcontroller sending telemetry than an entire embedded pc

y

What’s lightweight Linux

Yea I was considering getting one

Anything I should at-least start on learning to develop on os

as for machine learning, that stuff is ludicrously complex

Not the stuff you want to be writing from the ground up

I found this

Should I try this
