Hello. Sorry for maybe newbie question. I try to enable DS18B20 on my tinkerboard. The Armbian version is 21.08.1_Tinkerboard_buster_current_5.10.60. I've read the documentation about DTC, but I see no /boot/dtb/overlay directory, just /boot/dtb. I copied decompiled version of dtb from TinkerOS to this folder, compile it to rockchip-w1-gpio.dtb, but there is no /sys/bus/w1 folder.
dmesg|grep w1 is empty.
Here is my dts file:
/dts-v1/;
/ {
compatible = "rockchip,rk3288-miniarm", "rockchip,rk3288";
fragment@0 {
target-path = [2f 00];
__overlay__ {
onewire@0 {
compatible = "w1-gpio";
pinctrl-names = "default";
pinctrl-0 = <0x1>;
gpios = <0xffffffff 0x11 0x0>;
status = "okay";
phandle = <0x2>;
};
};
};
fragment@1 {
target = <0xffffffff>;
__overlay__ {
w1_pins@0 {
rockchip,pins = <0x0 0x11 0x0 0xffffffff>;
phandle = <0x1>;
};
};
};
__symbols__ {
w1 = "/fragment@0/__overlay__/onewire@0";
w1_pins = "/fragment@1/__overlay__/w1_pins@0";
};
__fixups__ {
gpio0 = "/fragment@0/__overlay__/onewire@0:gpios:0", "/fragment@1:target:0";
pcfg_pull_up = "/fragment@1/__overlay__/w1_pins@0:rockchip,pins:12";
};
__local_fixups__ {
fragment@0 {
__overlay__ {
onewire@0 {
pinctrl-0 = <0x0>;
};
};
};
};
};
Here is my armbianEnv.txt:
verbosity=1
bootlogo=false
overlay_prefix=rockchip
overlays=i2c1 i2c4 spi2 spidev2 uart1 uart2 w1-gpio
rootdev=UUID=acb95555-1de2-4b72-85c7-28b7b9d1a84e
rootfstype=ext4
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u
Am I on a right way to activate 1-wire driver? Shall I use another method to add new device to DT on this OS version?
