[U-Boot] U-Boot doesn't detect Pine64-LTS MMC

[AndroidT Tester]

Hello

I followed the instructions here:
https://openbsdmailbox.blogspot.com/2018/04/re-pine64-lts-cant-detect-disk_41.html

Here's all I did:

dd if=miniroot65.fs of=/dev/rsd0c bs=1m
mount /dev/sd0i /mnt
cd /mnt
cp /usr/local/share/dtb/arm64/allwinner/sun50i-a64-sopine-baseboard.dtb .
mkdir allwinner
cp sun50i-a64-sopine-baseboard.dtb allwinner/sun50i-a64-pine64-plus.dtb
cd ~
umount /mnt
dd if=/usr/local/share/u-boot/sopine_baseboard/sunxi-spl.bin of=/dev/sd0c
bs=1024 seek=8


I still can't get it to work.
This is what I get:

Device 0: device type unknown
... is now current device
