Hi,
I am using R32.6.1，is it possible to enable IMX390+GMSL on TX2-NX? I tried to add the dts based on tegra186-quill-camera-imx390-a00.dtsi and tegra186-camera-imx390-a00.dtsi(using pca954x), but it failed. Then I tried to modify the dts based on tegra186-camera-lanai-rbpcv2-imx219.dtsi(using cam_i2cmux), it also failed.

How to modify the DTS to enable the IMX390+GMSL on TX2-NX?

thinks in advance

hello Jinhao,

virtual channel should also supported with TX2 NX.
as you can see in developer guide, Jetson Virtual Channel with GMSL Camera Framework. it applies to: Jetson AGX Xavier series and Jetson TX2 series.

according to kernel logs…

[    1.442487] tegra-i2c 3180000.i2c: no acknowledge from address 0x70
[    1.442535] max9296 30-0048: max9296_write_reg:i2c write failed, 0x10 = 2

there’re communication failures, such as… i2c no acknowledge, and also i2c write failed.
these errors usually caused by incorrect regulator settings, or incorrect i2c bus/address of your device connections.

Hello JerryChang,

I’ve read the doc, and did some experiments.

According to the tegra186-cvb-prod-p2597-b00-p3489-1000-a00-00.dtsi. I manually added gpio_i2c_0_77,en_vdd_cam,en_vdd_cam_1v2 in file sources/hardware/nvidia/platform/t18x/lanai/kernel-dts/common/tegra186-p3636-0001-a00-power-tree.dtsi

{
	i2c@316000 {
		gpio_i2c_0_77: gpio@77 {
			compatible = "ti,tca9539";
			reg = <0x77>;
			gpio-controller;
			#gpio-cells = <2>;
			vcc-supply = <&battery_reg>;
		};
	};

	fixed-regulators {
			...

			/* Refered by IMX390 */
			
			en_vdd_cam: regulator@205 {
				compatible = "regulator-fixed-sync";
				reg = <205>;
				regulator-name = "en-vdd-cam";
				regulator-min-microvolt = <1800000>;
				regulator-max-microvolt = <1800000>;
				gpio = <&gpio_i2c_0_77 9 1>;
				enable-active-high;
			};

			/* Refered by MAX9296 */
			en_vdd_cam_1v2: regulator@12 {
				compatible = "regulator-fixed-sync";
				reg = <12>;
				regulator-name = "en-vdd-cam-1v2";
				regulator-min-microvolt = <1200000>;
				regulator-max-microvolt = <1200000>;
				gpio = <&gpio_i2c_0_77 10 0>;
				enable-active-high;
			};

			
	};
};

With the new dtb file, the device boot log outputs

When I remove the “gpio = <&gpio_i2c_0_77 10 0>;” from en_vdd_cam_1v2, it seems all drivers probes are success but failed to communicate with devices.

is gpio_i2c_0_77 necessary to en_vdd_cam and en_vdd_cam_1v2? How can I fix it? I am using TX2 NX devkit. Only one IMX390 and serializer board are connected to MAX9296 deserializer board.

hello Jinhao,

this should be failure by i2cmux, please check you enable TCA9546.
or… you don’t need i2c bus multiplexer since you’ve only single camera in your system.
