SK-AM62A-LP: CSIRX VIRTUAL CHANNEL

Kim TaeJung
Intellectual 620 points
Part Number: SK-AM62A-LP

Tool/software:

Currently, I am receiving 2 camera data via CSIRX as a virtual channel.

I created a video node via media-ctl.

However, when I stream one camera, it does not stream from the other camera.

After running it once, only one camera streams.

Are there any points to check?

media-ctl :

    Hi Kim,

    The expert in this matter is out of office until Friday.

    Meanwhile, would you please consider the following?

    • What camera models are you using, what resolution, are the drivers available?
    • How are you connecting them to the singly physical CSI port?
    • What do you mean by streaming? Display directly to the screen or stream over Ethernet? 
    • More details about multiple cameras on AM62A are available in this app note: https://www.ti.com/lit/an/spradh2a/spradh2a.pdf. 

    Best regards,

    Qutaiba

    Hi Saleh

    I am using an image sensor that outputs 1920x1080 UYVY data.

    I am connecting to one csi port.

    I want to output the camera screen to the screen using gstreamer.

    Currently configuring video3 and video4 with virtual channels.

    Is it possible to run video3 and video4 independently through virtua channels?

    Currently, video3 cannot be run independently, and video4 must be run to capture.

    Regards,

    Kim

    Hi Kim,

    How are you connecting two camera to the singly physical CSI port?

    Are you using V3link kit with AM62A board to connect multiple cameras?

    Hi

    We have created a custom board that can be connected to the CSI PORT on the AM62A SK board.

    Two cameras are transmitted to one CSI port via SER/DES structure.

    Hi Kim,

    To help you further, I need a bit more information. Could you elaborate on some of these points?

    1. What SER/DES solution are you using? (e.g., FPD-Link III, GMSL, MIPI D-PHY to something custom?) Knowing the specific SER/DES components will help understand the data transmission capabilities and potential limitations.

    2. How is the data from the two cameras being multiplexed onto a single SER/DES link?

    Hi

    We are using SER/DES (GMSL) from MAXIM company.

    We are connecting 2 cameras connected to SER to DES and transmitting them to AM62A via Virtual Channel.

    Hi Kim,

    Kim TaeJung said:

    This should be possible as long as your sensor driver and the serdes manage the virtual channels correctly.

    The "media-ctl -p" log looks fine to me, but your yavta log seems to show the following for both video3 and video4:

    max96712 4-0029: Mapping sink 0/1 to output VC 1, type 2,30
    Shouldn't the VC number be different?

    Hi

    How should the output be originally?

    The newly discovered symptom is that when video4 is executed, video3 also runs.

    However, in the above situation, video3 alone does not work.

    When the gstreamer command is run alone, video4 works, but video3 does not.

    However, if you run video3 and video4 at the same time, output is possible.

    Hi Xu

    After adding VC channel 2, I am getting start error in subdev as below.

    Are there any points to check?

    The newly discovered symptom is that when video4 is executed, video3 also runs.

    However, in the above situation, video3 alone does not work.

    Which SDK version are you using? Do you have a sensor with 3 virtual channels or do you have 3 sensors?

    How did you set up the media device topology? Can you try not to use DMA context 0? Another word, do not use  "30102000.ticsi2rx context 0" and start from  "30102000.ticsi2rx context 1".

    Hi

    I am using SDK version 10.01.00.05.

    I am using a total of 3 sensors.

    The above symptoms are the results of testing with 2 sensors.

    I plan to use 3 sensors in the future.

    I referred to the setup_scripts.sh file ov2312 settings for the media device topology.

    Hi

    After moving to 30102000.ticsi2rx context 1, I changed the nodes to video4, video5.

    But the symptoms are the same as before.

    OV2312 is a single sensor with 2 virtual channels. Please follow the IMX390 example in /opt/edgeai-gst-apps/scripts/setup_cameras.sh. If you have multiple IMX390 sensors, this script should set it up like below:

    Hi

    The overall structure is as follows.

    The media-ctl -p log you provided shows that each of the two ser devices has one sensor connected. 

    Is this correct?

    Regards,

    Kim

    Hi Kim,

    Thanks for sharing the diagram. You probably want to check with the serdes vendor on how the serdes manage and communicate with the sensors.

    Regards,

    Hi

    e2e.ti.com/.../sk-am62a-lp-problems-with-multi-camera-connection
    The current situation seems similar to issue #2 in the link above.

    Is this correct?

    The answer says it will be resolved in version 10.0, but is this still not resolved?

    Regards,

    Kim

    Hi Kim,

    The issue has been fixed, but skipping DMA context 0 can work around that issue.

    Hi

    I changed the configuration again and changed the context to 1.

    Videos 5 and 6 work independently, but 4 still has the same symptoms.

    Videos 4, 5, and 6 work normally when configured as a single channel, so it appears that the vc-id is being detected.
