[How to] Debian Stretch + Linux 4.9 from scratch (w/download, EMMC only)

Hello,
Sorry to polish this post, but I have the problem that Ajithbalakrishnan had, and he managed to solve without giving the solution.

Here is the problem :
"marc @ Khadas: ~ / project / linux $ sudo chroot / mnt / kvimrootfs mkinitramfs -o /boot/initrd.img $ (cat ~ / project / linux / include / config / kernel.release)
open / dev / fb0: No such file or directory
/etc/initramfs-tools/scripts/local-top/khadas_init.sh: 4: /etc/initramfs-tools/scripts/local-top/khadas_init.sh: can not create / sys / class / display / mode: Directory nonexistent
… "

Thank you for your answers.

Sincerely Marc.

PS : See [resolved] Pb with mkinitramfs .... open /dev/fb0: No such file or directory
