Jetson Agx Orin R36.3 argus_camera：No cameras available

[norman_xu]

Hi Support,

We are developing GMSL camera driver on Jetpack 6.0 (R36.3), and the argus_camera tool does not work. Please help check it, thanks.

1. DTS file

modules {
	status = "okay";
	module0 {
		status = "okay";
                badge = "cam0_bottomleft";
                position = "bottomleft";
                orientation = "1";
                drivernode0 {
                        status = "okay";
                        /* Declare PCL support driver (classically known as guid)  */
                        pcl_id = "v4l2_sensor";
                        devname = "imx728 30-001b";
                        /* Declare the device-tree hierarchy to driver instance */
                        sysfs-device-tree = "/sys/firmware/devicetree/base/bus@0/i2c@3180000/tca9546@70/i2c@0/cam_0@1b";
                };
	};
}:

2. Use the v4l2-ctl command to print the frame rate，it’s OK.

nvidia@nvidia-desktop:~$ v4l2-ctl -d /dev/video0 --stream-mmap
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.00 fps

3. When using the argus_camera tool, an error message appears: “No cameras available”.

Remove below to try. If still the same dump the dtb to confirm.

@norman_xu

devname = "imx728 30-001b";

Hi ShaneCCC,

We removed devname and converted the compiled dtbo file into a dts file, confirming that it had been removed, but arugs_camera still didn’t work. Are there any other ways to troubleshoot?

tegra-camera-platform {
	compatible = "nvidia, tegra-camera-platform";
	num_csi_lanes = <0x10>;
	max_lane_speed = <0x3d0900>;
	min_bits_per_pixel = <0x0a>;
	vi_peak_byte_per_pixel = <0x02>;
	vi_bw_margin_pct = <0x19>;
	isp_peak_byte_per_pixel = <0x05>;
	isp_bw_margin_pct = <0x19>;

	modules {
		status = "okay";

		module0 {
			status = "okay";
			badge = "cam0_bottomleft_sgcam0";
			position = "bottomleft";
			orientation = [31 00];

			drivernode0 {
				status = "okay";
				pcl_id = "v4l2_sensor";
				sysfs-device-tree = "/sys/firmware/devicetree/base/bus@0/i2c@3180000/tca9546@70/i2c@0/cam_0@1b";
			};
		};

		module1 {
			status = "okay";
			badge = "cam1_bottomright_sgcam1";
			position = "bottomright";
			orientation = [31 00];

			drivernode0 {
				status = "okay";
				pcl_id = "v4l2_sensor";
				sysfs-device-tree = "/sys/firmware/devicetree/base/bus@0/i2c@3180000/tca9546@70/i2c@0/cam_1@1c";
			};
		};
}

The num_csi_lanes doesn’t looks like right.

Hi ShaneCCC，

After adding the following configuration, argus_camera can work. thanks.

cam_0@1b {
    .....................................
	physical_w = "15.0";
	physical_h = "12.5";
	.....................................
}
