Is SPI Working?

[User 3332]

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

In the file.dts I found the following, do we need to edit anything with that also? (says "io_disabled")

  spi0@2 {
                                allwinner,pins = "PC3", "PC2", "PC0", "PC1";
                                allwinner,function = "io_disabled";
                                allwinner,muxsel = <0x7>;
                                allwinner,drive = <0x1>;
                                allwinner,pull = <0x0>;
                                linux,phandle = <0x55>;
                                phandle = <0x55>;
                        };
