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
