Did you guys build this, or is it copied from somewhere?
Basic rootfs
Download the basic rootfs from FTP server with user 'ftp' (password: lindeni) and store to debian directory.
It needs the ALSA headers installed into it.
I would recommend using buildroot instead of debian. buildroot will let you control exactly what is in the image you build.

With buildroot you can make a single config file that can make the V5 kernel, V5 uboot and even the examples. Then turn it all into an image.
