CAN Bus Support for Nanopi-NEO-Plus2

[TEKZOOM]

Hi, I tried to add the mcp251x overlay for Nanopi-NEO-Plus2 (Allwinner H5) using armbian-add-overlay command but got the error below. Does anybody know why? Below, you can find the dts file. Any help would be appreciated.

Compiling the overlay
dtc: livetree.c:521: get_node_by_phandle: Assertion `(phandle != 0) && (phandle != -1)' failed.
/usr/sbin/armbian-add-overlay: line 76:  2078 Aborted  dtc -@ -q -I dts -O dtb -o ${temp_dir}/${fname}.dtbo $1
