fixed, not actual, thanks for everyone and this resource

bpi 2w zero runs at H3, and self writed overlay for double mcp2515, now trying to migrate from uSD to emmc and H618 M4 zero.. but it's unreal? how to debug overlays step-by-step and all pheriperal pin-by-pin to detect any missclick's or conflict?, overlay compiled and applied without any notices... Applying kernel/user provided DT overlay **any**.dtbo failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND why FDT_ERR_NOTFOUND ?? default mcp2515 kernel overlay look like a joke: /dts-v1/; /plugin/; / { fragment@0 { target = <&spi1>; __overlay__ { status = "okay"; }; }; fragment@1 { target = <&can>; __overlay__ { status = "okay"; }; }; }; ofcource it's have same problem - FDT_ERR_NOTFOUND

any one have a succes with? using Armbian_25.2.2_Bananapim4zero_noble_current_6.6.75.img wifi not work, thats fixed with: overlays=bananapi-m4-sdio-wifi-bt Applying kernel provided DT overlay sun50i-h616-mcp2515.dtbo failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND and then: Error applying DT overlays, restoring original DT and have no wifi and any overlays at all.. on a bpi 2W Zero runs double mcp2515 on a spi1 as can0 + can1, but on M4 zero - no success at all, everythings are tried, all armbian builds, trying self writed overlays, tried boot from uSD, emmc - no success. always took this: Applying kernel/user provided DT overlay **any**.dtbo failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND
