Hello.

I am trying to boot Linux on stm32f429-disco and currently get the problem:

Seems that kernel does not understand where is place of init ramfs.
Maybe need to some additional changes in Linux kernel to run it?

With best regards,

What would it take to compile Linux + flash it to this device?
