Boot process - technical

I am looking for behavior within boot process for Rock Pi 4B. We know that boards are looking for specific boot code (MBR/GPT), then file systems and files inside, but we don’t know how this does exactly happen and in what order.

I am asking for my own research, but I think many of us would like to know how the boot process happens.

Can Radxa share this info?

you can check the detailed boot flow from the following wiki:

it’s well documented.
