1-Wire DS18B20 on Jetson Orin DevKit

[vladimir.tchernitski]

Continuing the discussion from Enable 1-Wire on Jetson Orin DevKit:

Hello,

Got it to work on Orin AGX DevKit,

In Orin Jetson AGX pinmux config xlsm I changed GPIO9 (GPIO324) to Open Drain + PullUP

Re-flashed the device and followed the post 1-wire DS18B20 Thermometer on Jetson Xavier AGX

In tegra234-p3737-0000+p3701-0000.dts added

onewire@0 {
		compatible = "w1-gpio";
		gpios = <&gpio_aon TEGRA234_AON_GPIO(BB, 0) GPIO_ACTIVE_HIGH>;
		status = "okay";
	};

GPIO9 (GPIO324) is pin 32

hello vladimir.tchernitski,

may I know what’s the latest status? or… it’s a working use-case sharing of 1-Wire DS18B20?

Hello Jerry,

yes it’s the working solution.
