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.
