[nanopi neo2] Module softdog not found in directory

Hi guys,

I have just installed Armbian on my nanopi neo2 which works in 1-bay NAS Kit v1.2 for NanoPi NEO&NEO2 (http://www.friendlyarm.com/index.php?route=product/product&product_id=192)

I have installed Armbian from image (https://dl.armbian.com/nanopineo2/Debian_stretch_next.7z). The only thing that works on it is OMV which was installed via armbian-config

My system is:

root@openmediavault:/# uname -a

Everything seems to be fine except watchdog module.

Maybe someone of you has idea how to fix it or even workaround it?
