Hi All,

I am working on Jetson Tx2 board. In device tree, camera plugins are available. How the Plugin manager gets Camera Id from Boot loader or How Plugin Manager works? please provide this information, since to modify the device tree, it makes the confusions.

-Thanks.

You need have EEPROM on your board and write the data “3326” to the EEPROM for reginization.

tegra186-quill-camera-plugin-manager.dtsi

		fragment-e3326@0 {
			ids = "3326-*";
			override@0 {



tegra186-quill-p3310-1000-a00-plugin-manager.dtsi    declaration EPPROM slave address

		bus@3 {
			i2c-bus = <&cam_i2c>;
			eeprom@0 {
				slave-address = <0x54>;
				label = "cam";
				enable-gpio = <2 9>;
			};
		};

Which EEPROM chip is used for save the “3326” value?
