Re: [RaspberryPI 3B] [unicorn Hat] [how to configure spi]

["Pierre-Francois RENARD" <pfrenard@xxxxxxxxx>]

Ok, I worked a little on this issue and I found something.

module spidev is not loaded, so it tried to load it with modprobe spidev.
it worked but nothing was created into /dev

I also ran  dtc -Ifs /proc/device-tree 
and found

spi@7e204000 {
                        compatible = "brcm,bcm2835-spi";
                        clocks = <0x7 0x14>;
                        status = "disabled";
                        #address-cells = <0x1>;
                        interrupts = <0x2 0x16>;
                        #size-cells = <0x0>;
                        reg = <0x7e204000 0x1000>;
                };

spi@7e215080 {
                        compatible = "brcm,bcm2835-aux-spi";
                        clocks = <0xf 0x1>;
                        status = "disabled";
                        #address-cells = <0x1>;
                        interrupts = <0x1 0x1d>;
                        #size-cells = <0x0>;
                        reg = <0x7e215080 0x40>;
                };

spi@7e2150c0 {
                        compatible = "brcm,bcm2835-aux-spi";
                        clocks = <0xf 0x2>;
                        status = "disabled";
                        #address-cells = <0x1>;
                        interrupts = <0x1 0x1d>;
                        #size-cells = <0x0>;
                        reg = <0x7e2150c0 0x40>;
                };

but status of these trees is "disabled" ... 
how can I enable them, that will probably creat the devices into /dev :)

Thanks a lot
