Camera fail on agx Orin 32GB JatPack 5.1.2

We use the imx185 v2 version of the driver, which is no problem on Xavier.
There are 2 ub964 and two video nodes on our hardware design.
When put on Orin, a node with 12bit camera and a node with 10 bit camera will not get the frame.
only 12 bits is no problem.

When put on Orin, a node with 12bit camera and a node with 10 bit camera will not show the graph.
Plugging in 12 bits alone is no problem.

But a few of them still print out a little wrong.
The values of pix_clk_hz and deskew_initial_enable in sys fs are correct for the device tree.

But when dump the picture use v4l2-ctl , the csi inside is not right;

Does this have anything to do with the dump failure?
By what is this CSI and the numerical value that drives the initialization related?

hello Yanhou.LI,

I’ve tested IMX185 on JP-5.1.2 and confirm it works normally.
may I know what’s your test pipeline? did you enable use_sensor_mode_id and using --set-ctrl sensor_mode=<N> to select the modes for testing?

Thanks for your reply
use_sensor_mode_id was not configured before
But my configuration to true is not resolved either

I found a problem,
When the MIPI clock is not recognized, it can be plotted when the mipi is set to the default 250000Khz
But when it is recognized as something else, it cannot be plotted.
What’s wrong with that

Here is log.

hello Yanhou.LI,

it looks you’ve apply debug rce-fw which enable some additional messages.
may I know you’re using the correct version, is it the camera firmware with r35.4.1 release version?

BTW,
your failure logs has short frame error reported, which might be the coming signaling is less than expectation.
you may examine your sensor side configuration.
for instance,
CHANSEL_SHORT_FRAME channel:0x04 frame:2 vi_tstamp:154123425888 data:0x00fa200001000000

Yes. I use debug rec-fw from GMSL Camera fail on Orin Nano JatPack 5.1.2 - #4 by marco.ferretti

We create the /dev/video node using an empty frame.
This is a virtual node and we just connect the node to the CSI.
What are the parameters that are necessary to use this way?

			mode0 {
				mclk_khz = "24000";
				mclk_multiplier = "25";
				pix_clk_hz = "200000000";

				num_lanes = "4";
				tegra_sinterface = "serial_e";
				// pixel_t = "yuv_yuyv16";
				// csi_pixel_bit_depth = "16";

				csi_pixel_bit_depth = "16";
				mode_type = "yuv";
				pixel_phase = "yuyv";

				deskew_initial_enable = "false";
				// deskew_initial_enable = "true";
				// serdes_pix_clk_hz = "200000000";

				// mode_type = "bayer";
				// pixel_phase = "rggb";
				// csi_pixel_bit_depth = "12";				

				active_w = "1280";
				active_h = "720";

				line_length = "2560";

				embedded_metadata_height = "0";				
			};

Sorry,
I got the log naming backwards.
Now it’s correct。

hello Yanhou.LI,

you can ignore this DT property, deskew_initial_enable, this is not used internally.
FYI,
it’s RCE firmware to handle deskew calibration, deskew calibration is a must if data-rate > 1.5 Gbps.
the MIPI clock-rate is derived within… $public_sources/kernel_src/kernel/nvidia/drivers/media/platform/tegra/camera/sensor_common.c
the clock has divide by 2 since data is sent on both rising/falling edges of clock. internally, it also have deskew threshold configure as… 1.5Gbps/2 = 750M

your tracing logs looks there’re frame packets on the VI channel, and its SOF/EOF has received correctly.
is it part of logs from functional camera node?

Thanks for your reply
I set use_sensor_mode_id = “true”; And pix_clk_hz = “125000000”;
mipi_clock is 250MKhz
So I plug in four lane cameras,
Using commands
v4l2-ctl -d /dev/video1 --set-fmt-video=width=10240,height=720,pixelformat=RG12 --stream-mmap --stream-count=10
It works,

hello Yanhou.LI,

may I have more details about the difference between functional/non-functional use-case?
besides, did you meant you’re going to enable gang mode?

10

I didn’t do virtual channels
A video node corresponds to a ub964 and a ub964 is connected to a maximum of four cameras
If plug in four lane cameras, the width will be 2560 * 4
If plug in one lane camera, the width will be 2560 * 1
I don’t know if I made myself clear

11

I see… one-lane failed due to the capture buffer has setup as 10240x720 for capturing.
for instance, tegra_channel_capture_setup: vnc_id 0 W 10240 H 720 fmt c4

could you please execute $ v4l2-ctl -d /dev/video0 --list-format-ext to examine the format dumps.
you should have another sensor mode setting for capture your one-lane sensor.
