It depends on how much tuning you're ready to make. Without doing a lot
of tuning, I would say 8 MB of RAM is really the minimum. And indeed
the STM32F4/STM32F7 platforms that can run Linux have 8 or 16 MB of
external RAM: https://elinux.org/STM32#STM32F4_based.

I have no idea which .bin files you're talking about.

A Linux kernel image.

A Device Tree file.
