Is SPI Working?

Yes the file is /boot/pine64/sun50i-a64-pine64-plus.dtb
First, backup that file somewhere, then decompile it :

dtc -I dtb -O dts -o file.dts /boot/pine64/sun50i-a64-pine64-plus.dtb

Edit it to place status = "okay", but you need to fix also the buggy 0x40000 in eth with the good value 0x10000.

Recompile it :

dtc -I dts -O dtb -o /boot/pine64/sun50i-a64-pine64-plus.dtb file.dts
