Gstnvarguscamerasrc.cpp, execute:751 Redistribute latency

I used a TP2854 chip to consolidate the data from four analog cameras and connected it to the CAM0 interface via the MIPI interface. I followed the driver code in nv_imx219.c to modify the source code for the TP2854. I2C communication is normal, and the device node can be registered successfully. However, when testing with the gstreamer command, I cannot obtain the correct output.
my cmd:

gst-launch-1.0 nvarguscamerasrc num-buffers=200 ! 'video/x-raw(memory:NVMM), width=1920, height=1080, framerate=25/1, format=NV12' ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=test.mp4 -e

The following error is displayed:

[   63.623322] tp2854_mipi 9-0044: tp2854_open:

I would like to know how to proceed from here. I also have a question: when porting files prefixed with “nv_”, can I only use nvarguscamerasrc to obtain data?

Information about the development board I am using:

uname -a
Linux xx 5.10.120-rt70-tegra #10 SMP PREEMPT RT Fri Feb 2 11:51:16 CST 2024 aarch64 aarch64 aarch64 GNU/Linux

Additional:
The document at Sensor Software Driver Programming — Jetson Linux Developer Guide documentation shows two programming paths: Camera Core Library Interface and Direct V4L2 Interface. However, I found that in the Kernel 5.10 code, all camera drivers start with “nv_”, and these codes are not the same as the general V4L2 structure. Can a solution like TP2854 be added to the driver in a way similar to the “Direct V4L2 Interface”?

Get the trace log to check if more clue.

The log I captured using the log tool is here. I am not very familiar with orin nx. The following is the log I captured:

do you have any ideas?

The trace log tell the SOT error that could be MIPI timing issue.
Please review the pix_clk_hz in device tree. And may need to probe the output signal.

Thanks

I modified pix_clk_hz

It doesn’t seem to be working, is this still a mipi problem?

7

Yes, still the SOT error tell the MIPI timing issue.

8

thank you for replay.I have some questions
1.I would like to know what is the general reason why SOT cannot be detected?
By the way, how to configure the internal mclk output clock? Is there any reference device tree configuration?
2.PHY_INTR0 phy:1 cil:0 st:0 vc:0 status:0x00000089 ,What does this output mean? Where can I find out what these error outputs mean?

  1. The SOT could be ths_settle timing cause like

    mipi_timeing
    mipi_timeing2126×1353 148 KB

  2. The mclk can configure in the sensor mode in device tree.(mclk_khz)

			mode0 {
				discontinuous_clk = "no";
				readout_orientation = [30 00];
				exposure_factor = "1000000";
				mclk_khz = "37125";

Check the REG NVCSI_PHY_0_CILA_INTR_0_STATUS_CILA_0 in TRM for the PHY_INTR0 message.

I’m not quite sure if there’s any issue with my other configurations that’s causing me to not be able to output content. So, I’m putting my device tree configuration here. Since I’m using tp2854 and it’s configured for 4-lane output, I noticed that the CAM1 interface on the carrier board supports 4-lane output. Therefore, I connected the interface to CAM1, and the main configuration should be in the i2c_1: i2c@1 section.

I also found that the error code reported was the phy:1 error. I would like to ask:

  1. I use the CAM1 port. Does phy1 here refer to CSI2_D0 or CSI2_D1, or something else?
  2. There are 4 virtual channels in the output of tp2854. How should I modify it so that it corresponds to video0-3 nodes?

If your sensor output as 4 lane the bus-width should be 4 instead of 2
