No, and from a quick read the STM32F767ZI Nucleo doesn't seem to have
external RAM, so only the RAM inside the MCU is available, and its size
is insufficient to run Linux. Are you sure it is possible to run Linux
on this specific board ?

We have existing configurations for two other STM32 boards, which have
external RAM, and are therefore able to run Linux:

  configs/stm32f429_disco_defconfig
  configs/stm32f469_disco_defconfig

Please read the Buildroot manual and the slides at
https://bootlin.com/doc/training/buildroot/buildroot-slides.pdf.
There's plenty of documentation available that explains what's in the
output/ folder.

It depends on your board.

If you can indeed run Linux (see point 1), then you can do
remote debugging, as explained in
https://bootlin.com/doc/training/buildroot/buildroot-slides.pdf slide
275 and following.

I had never heard of VisualGDB, but I guess it's just an UI on top of
GDB, so you should be able to do remote debugging as well.

Best regards,

Thomas
