No /dev/video0 node but sensor detected and driver loaded

I have AGX Orin dev kit with Jetpack 5.0.2 and two cameras. The driver is loaded and probed, but there is no /dev/video0 and /dev/video1. Please help.

The two cameras are connected to AGX Orin via LI-JTX1-MIPI-ADPT REV12 by Leopard Imaging Inc.

It could be the device tree problem.
Confirm the change the vi@xxxx{} to tegra-capture-vi{}

It is tegra-capture-vi{}.

The base of our sensor driver is imx274 dual. I am looking at the overlay file: tegra234-p3737-camera-dual-imx274-overlay.dts. Could you please let me know what is the “odm-data” and “ids” should be in this file? Below are two examples, and our connection board is LI-JTX1-MIPI-ADPT REV1.2 from Leopard Imaging. thanks

/* Enable VI ports - capture_vi_base, */
fragment@8 {
	target-path = "/tegra-capture-vi";
	board_config {
		odm-data = "enable-dual-imx274";
		sw-modules = "kernel";
	};
	__overlay__ {
		num-channels=<2>;
	};

/* Enable VI ports - capture_vi_base, */
fragment@34 {
	target-path = "/tegra-capture-vi";
	board_config {
		ids = "LPRD-dual-imx274-002";
		sw-modules = "kernel";
	};
	__overlay__ {
		num-channels=<2>;
	};
};

Sorry for the late response, is this still an issue to support? Thanks

I would suggest consult to Leopard to get the driver would be greate.

Thanks

Thank you for your response!

It turned out that our camera was wrongly detected as imx185, and therefore the overlay of imx185 was applied instead of our own overlay. The workaround was delete the overlay of imx185 at configuration.
