Orange Pi PC+. Minimal image. Kernel mode driver ovpn-dco-v2

[fvgenn]

Im using Orange Pi PC+ with Debian 12 minimal image.
I tryed to install/compile ovpn-dco-v2 as of standard deb (openvpn-dco-dkms) as well as of git (https://github.com/OpenVPN/ovpn-dco).
In bouth cases compilation prcess itself was finished successfully but resulting driver ovpn-dco-v2.ko didn't work.
In the first case, the driver caused a kernel error.
In the second case, after "modprobe ovpn-dco-v2" , openvpn stuck somewhere in the middle and lsmod has hung down, blocking the console.

Before installing the driver package i did: 
apt install build-essential kmod debhelper devscripts linux-headers-current-sunxi
And as i thought everything went fine.

What did I do wrong? Which linux headers do I need to install: "current" or maybe "edge". Maybe some dependencies are broken... On x86 Debian everything works fine. Any ideas?
