[Buildroot] STM32F767ZI Nucleo

[Czybor Michael]

Hello,

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

the "binary stuff" could be the bootloader, is this right?

I found four versions (not five :-)):

a.) stm32f429i-disco.bin
b.) stm32f469i-disco.bin
c.) stm32429i-eval.bin
d.) stm32746g-eval.bin

But I started the build process only with one configuration?

One more question about the device-tree-file. If I like to use UIO-Devices, than I must edit the device-tree.

1.) Can I use UIO-Device-Drivers?

2.) How do I input a different device tree?

Thank you for your help and I see what my next steps are!

Best Regards,
Michael

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.

A file containing some binary stuff.

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

A Linux kernel image.

A Device Tree file.
