Uncorr_err: request timed out after 2500 ms(ORIN NX)

Jetson Module： ORIN NX

We used MIPI access GSML camera, the same set of hardware, in the use of L4T 35.4.1 version, the function is normal.

However, due to the actual requirements of the project, it is necessary to upgrade the system version to L4T 36.3.

During this process, we found that one of the GSML cameras could not preview the video properly, accompanied by the following error message.

[  219.176864] tegra-camrtc-capture-vi tegra-capture-vi: uncorr_err: request timed out after 2500 ms
[  219.176890] tegra-camrtc-capture-vi tegra-capture-vi: err_rec: attempting to reset the capture channel
[  219.177385] tegra-camrtc-capture-vi tegra-capture-vi: err_rec: successfully reset the capture channel

The following images are screenshots of the two interface tests. The camera in question opens with a green screen interface.

However, the normal camera can preview the video normally.

The commands to preview the video stream are consistent.

gst-launch-1.0 -v v4l2src device=“/dev/video3” ! video/x-raw,framerate=30/1,width=1920,height=1080 ! xvimagesink

gst-launch-1.0 -v v4l2src device=“/dev/video2” ! video/x-raw,framerate=30/1,width=1920,height=1080 ! xvimagesink

Attached is the dmesg information before and after the system test camera.
dmesg.txt (61.4 KB)
dmesg_test_old.txt (68.4 KB)

To make this easier to distinguish, after testing the camera that previewed the video stream correctly, I plugged and unplugged the keyboard and mouse devices on the device so that I could distinguish the dmesg information generated by testing the problematic camera.

The information about --plink-- in dmesg is simply printed as a breakpoint that we added during the debugging of this version of the driver.

Here is the dts file I used, adapted for the new version.

I hope someone can help to solve this problem, which has been bothering us for half a month

[JerryChang]

may I know how many cameras in your system, which is the problematic? for instance, which CSI port is video3 used.

[chen.xi]

There should be four in the normal whole street, but actually only two GSML interfaces are elicited, and the test is performed with only one camera.

[chen.xi]

In the beginning, video0 and video1, but neither of them could preview the graphics, at least one of them was able to preview the images after modification based on this post.

Orin Nano Devkit JetPack6.0 i2c-mux 9/10 chan_id different with JetPack5.1.2

Hi ShaneCCC， JetPack5.1.2 i2c-9 = i2c-mux-chan_id 0, i2c-10 = i2c-mux-chan_id 1 But JetPack6.0 i2c-9 = i2c-mux-chan_id 1, i2c-10 = i2c-mux-chan_id 0 My question is why the chan_id is different in JetPack6.0

[chen.xi]

Both video2 and video3 are connected under this connector.

[chen.xi]

Before opening the camera, it is necessary to initialize the camera through a fixed procedure in order to determine the access to videoX

[JerryChang]

hello chen.xi,

I’m still don’t understand, which of the camera node is the problematic.
or… when I dig into DTS file, which node should I look into?

[chen.xi]

This means that my current video2 can preview video stream normally, but video3 can not.

They are actually connected to the same FPC connector. The signal definition of this connector is the screenshot I sent above.

[chen.xi]

Also, if there is any official documentation for nodes tegra-capture-vi and nvcsi@15a00000 in the Jetson system

In short, as of version 35.4.1, part of the screenshot should be :

port@0   <----->  max9296_a_vi_in0
port@1   <----->  max9296_a_vi_in1
port@2   <----->  max9296_b_vi_in0
port@3   <----->  max9296_b_vi_in1

However, with this configuration, it is not possible to preview the image of any video device in L4T36.3.

video2 can then preview the video stream after changing it to something in a screenshot, or something in the dtsi I uploaded earlier.

The v4l2-ctl command also seems to be looking at the wrong information.

nvidia@tegra-ubuntu:~$ v4l2-ctl --list-devices
NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca):
        /dev/media0

vi-output, camera_sensor 9-001c (platform:tegra-capture-vi:0):
        /dev/video0
        /dev/video1
        /dev/video2

vi-output, camera_sensor 10-001 (platform:tegra-capture-vi:2):
        /dev/video3

[JerryChang]

hello chen.xi,

here’re incorrect settings, please update those as 2-lane and using corresponding port index.
num_lanes = 4;
tegra_sinterface = serial_a;

and…
this node did not match to your capture-vi settings, please revise it accordingly.

ports {
    max9296_b_out1: endpoint {
        vc-id = <1>;
        port-index = <3>;   <== it should be port-index = <2>
        bus-width = <2>;
        remote-endpoint = <&max9296_b_csi_in1>;

[chen.xi]

Is that the correspondence?

CSI0 <----> serial_a
CSI1 <----> serial_b
CSI2 <----> serial_c
CSI3 <----> serial_d

[JerryChang]

hello chen.xi,

according to your device tree definition, you’ve enabling virtual channel supports, it’s two cameras went through CSI-A (CSI0), and the other two cameras went through CSI-C (CSI2).

Orin Nano Devkit JetPack6.0 i2c-mux 9/10 chan_id different with JetPack5.1.2

Hi ShaneCCC， JetPack5.1.2 i2c-9 = i2c-mux-chan_id 0, i2c-10 = i2c-mux-chan_id 1 But JetPack6.0 i2c-9 = i2c-mux-chan_id 1, i2c-10 = i2c-mux-chan_id 0 My question is why the chan_id is different in JetPack6.0

Please ask if this thread means:

Jetpack5.1.2
/dev/i2c-9  <---------->  i2c@0   <------------>   CAM0_I2C

but
Jetpack6.0
/dev/i2c-9  <-----------> i2c@1  <------------->  CAM1_I2C

Is that what it means?

[JerryChang]

hello chen.xi,

A port-index property in the device tree is using to specify the CSI brick.
you may see-also Topic 69753 for reference.

[chen.xi]

Thank you very much. There is still a question. I have confirmed with the hardware, we actually only receive signals from CSI0 and CSI2, CSI0 and CAM0_I2C in a MIPI connector, CSI2 and CAM1_I2C in a MIPI connector.

Follow my device tree configuration.

sensor connect to CSI-A
Sensor_out (port-index= 0) →CSI_in (port-index= 0) → CSI_out (port-index= 0) → VI_in (port-index= 0)
and tegra_sinterface = serial_a;

sensor connect to CSI-C
Sensor_out (port-index= 2) →CSI_in (port-index= 2) → CSI_out (port-index= 2) → VI_in (port-index= 2)
tegra_sinterface = serial_c;

Is that what it means?

[JerryChang]

yes, that’s what my previous comment #13 has point-out, please revise that accordingly.

[chen.xi]

The camera is ready to preview, but there’s still one problem,

Our camera initialization program initialized successfully video2 and video3 can be opened, but this problem does not exist in L4T 35.4.1 version. I tried to modify the order under i2c@0 node, but it did not work.

tegra234-camera-max9296-plink-overlay.zip (3.4 KB)

Can you help me see how I can adjust it to ensure that the application successfully initializes the video device, which is the same as the one successfully opened using GST-launce-1.0? Without changing our program,

[JerryChang]

hello chen.xi,

did you meant you’re able to stream video3 after modify the device tree port bindings?
what’s the failure now, please open another new thread for tracking new issues.
