The nand firmware is not ready yet for v3, that is why it is not included in the image builder yet.
For your coreutils-timeout issue, that seems to be a wide problem in linux.
Don’t install it as a package, instead place the binaries and other files into the “buildroot/files” directory and they will be included into the image. Make sure the directory structure is correct in files, ie “buildroot/files/sbin/mybin” for example, for mybin to be placed in sbin of the image.
