hi every one,

i’m trying to get sony imx219 working on tx2(R32).and now,i can use the below command to capture stream,it’s ok:

v4l2-ctl --set-fmt-video=width=3280,height=2464,pixelformat=RG10 --stream-mmap --set-ctrl=sensor_mode=0 --stream-count=3 -d /dev/video0

but,when i use gstreamer, it was failed.

root@tek:~# gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM), width=3280, height=2464, format=(string)NV12, framerate=(fraction)30/1' ! nvoverlaysink -e

That must be the device configure cause this kind of problem.
Confirm you DT with your source. Check the extracted_proc.dts with your dtsi

$ sudo apt-get update
$ sudo apt-get install device-tree-compiler

$ sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

yes, i did,Same as my modified.

why is v4l2 ok, and gstream is fail. What dose the mean of “execute:521 No cameras available”.

Confirm the devname is the same as kernel driver name.

modules {
 			module0 {
 				badge = "e3326_front_P5V27C";
 				position = "rear";
 				orientation = "1";
 				drivernode0 {
 					/* Declare PCL support driver (classically known as guid)  */
 					pcl_id = "v4l2_sensor";
 					/* Driver v4l2 device name */
 					devname = "ov5693 2-0036";
 					/* Declare the device-tree hierarchy to driver instance */
 					proc-device-tree = "/proc/device-tree/i2c@3180000/ov5693_c@36";
 				};

here is my dts:

modules {

			module0 {
				badge = "e3326_front_P5V27C";
				position = "rear";
				orientation = [31 00];
				status = "disabled";
				linux,phandle = <0x10f>;
				phandle = <0x10f>;

				drivernode0 {
					pcl_id = "v4l2_sensor";
					devname = "imx219 2-0010";
					proc-device-tree = "/proc/device-tree/i2c@3180000/imx219@10";
					status = "disabled";
					linux,phandle = <0x110>;
					phandle = <0x110>;
				};

and the below is copy from proc/device-tree:

module0 {
				badge = "e3326_front_P5V27C";
				status = "okay";
				phandle = <0x10f>;
				position = "rear";
				linux,phandle = <0x10f>;
				orientation = [31 00];

				drivernode1 {
					pcl_id = "v4l2_lens";
					status = "okay";
					proc-device-tree = "/proc/device-tree/e3326_lens_ov5693@P5V27C/";
					phandle = <0x111>;
					linux,phandle = <0x111>;
				};

				drivernode0 {
					devname = "imx219 32-0010";
					pcl_id = "v4l2_sensor";
					status = "okay";
					proc-device-tree = "/proc/device-tree/i2c@3180000/imx219@10";
					phandle = <0x110>;
					linux,phandle = <0x110>;
				};

and the below is my kernel driver:

static const struct i2c_device_id imx219_id[] = {
	{ "imx219", 0 },
	{ }
};
MODULE_DEVICE_TABLE(i2c, imx219_id);

static struct i2c_driver imx219_i2c_driver = {
	.driver = {
		.name = "imx219",
		.owner = THIS_MODULE,
		.of_match_table = of_match_ptr(imx219_of_match),
	},
	.probe = imx219_probe,
	.remove = imx219_remove,
	.id_table = imx219_id,
};

The status was override to disable by the plugin manager that must be the reason.
You may need to disable the plugin manage.

yes,i have already disabled plugin manager.at the same time,i check them under /proc/device-tree folder.

The devname = “imx219 32-0010” looks not correct? Should it be imx219 2-0010?
Check the bus number by v4l2-ctl --list-devices

good news,it’s the root cause.this issue was resovled.

thanks.
