mtr46 got a reaction from
Myy in RK3288 device tree overlays
The problem has been solved.
I rewrote the DTS as follows:
/ {
w1 {
compatible = "w1-gpio";
pinctrl-names = "default";
pinctrl-0 = <&w1_gpio_pins>;
gpios = <&gpio0 17 0>;
};
};
&pinctrl {
onewire {
w1_gpio_pins: w1-gpio-pins {
rockchip,pins = <0 17 0 &pcfg_pull_up>;
};
};
};
I am now able to use 1-wire.
results:
