Embedded Linux without Yocto (programming.dev)

Hello all, I'm an embedded software guy struggling with Yocto. I'm not asking for assistance as I cannot be saved. Rather, I'd like to make my own. How hard it would be to put a Linux distro onto a device without it? For example, if I were to get a perfectly good distro (let's just say Debian) with the right architecture going in a container. Is there a simple way to combine that with u-Boot, and other crap from a SoC manufacturer to build an image? If that is oversimplifying, I've done Linux from scratch before, and I'd be willing to go that route as well. I guess the issue boils down to the specifics like building the image and anything else that I'm not aware of.

So, what part of this idea is going to be a lot harder than I'm giving it credit for?

By the way, I'm aware of Buildroot. This is more for learning purposes, and who knows... maybe I will actually make something out of it.

Right now, the most common target we have at work is variscite imx6,7 and 8. Nxp has leaned heavily into yocto. To be clear, this would be an outside of work thing, but I'll probably yoke one of our dev boards.

Yeah you’re right, NXP does lean into Yocto. The IMX line has good support with it. You might have the flexibility of going with the community built BSPs and/or vanilla Linux kernel, if you don’t want to rely fully on NXP written software. I’m not 100% certain on the support for your boards under the community supported repos, so you’ll have to look into your exact use case. But it does give you some options.
