Thanks.

Tell me, please.
Where must I put sun8i-h3-opp.dtbo file?
/boot/dtb/overlays/ or /boot/msdos/dtb/overlays/ ?

Do files sun8i-h3-sid.dtbo,sun8i-h3-ths.dtbo is from https://people.freebsd.org/~ganbold/dtb/ ?

What is sun8i-h3-nanopi-r1.dtb and sun8i-h3-nanopi-r1-new.dtb?
How do they differ from  /boot/msdos/dtb/sun8i-h3-nanopi-neo.dtb ?
