If you find any problem tell me.   First go to armbian-config to change some kernel with has his own headers available like 6.10.9 (i had problem with rebooting with 6.7.12) configure an internet connection unpack the attached file to root dir / cd /linux_openvfd cp openvfd.dts /boot/dtb/allwinner/overlay/
