[参考译文] SK-AM62A-LP：CSIRX 虚拟通道

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1539746/sk-am62a-lp-csirx-virtual-channel

器件型号：SK-AM62A-LP


工具/软件：

目前、我正在通过 CSIRX 接收 2 个摄像头数据作为虚拟信道。

我通过 media-ctl 创建了一个视频节点。

但是、当我流式传输一个摄像头时、它不会从另一个摄像头流式传输。

运行一次后、只有一个摄像头进行流式传输。

是否有需要检查的要点？

media-ctl：

    尊敬的 Kim：

    此问题的专家在星期五之前不在办公室。

    同时、 请您 考虑以下事项吗？

    • 您使用的摄像头型号是什么、分辨率是什么、有哪些驱动程序可用？
    • 如何将它们连接到单个物理 CSI 端口？
    • 您的意思是流式传输？ 直接显示到屏幕上还是通过以太网流式传输？  
    • 有关 AM62A 上多个摄像头的更多详细信息、请参阅以下应用手册： https://www.ti.com/lit/an/spradh2a/spradh2a.pdf。  

    此致、

    嗨、Saleh

    我使用的是输出 1920x1080 UYVY 数据的图像传感器。

    连接到一个 CSI 端口。

    我要使用 gstreamer 将摄像头屏幕输出到屏幕。

    当前正在配置具有虚拟通道的 video3 和 video4。

    是否可以通过虚拟通道独立运行 video3 和 video4？

    目前、video3 不能独立运行、而且必须运行 video4 才能捕获。

    此致、

    Kim

    如何将两个摄像头连接到单个物理 CSI 端口？

    您是否使用 V3link 套件和 AM62A 板来连接多个摄像头？

    你（们）好

    我们创建了一个可连接到 AM62A SK 板上 CSI 端口的定制电路板。

    两个摄像头通过 SER/DES 结构传输到一个 CSI 端口。

    尊敬的 Kim：

    为了进一步帮助您、我需要更多信息。 您能否详细说明一下其中的一些要点？

    1. 您使用的是什么 SER/DES 解决方案？ （例如，FPD-Link III、GMSL、MIPI D-PHY 属于定制器件？） 了解特定的 SER/DES 元件将有助于了解数据传输能力和潜在的限制。

    2. 来自两个摄像头的数据是如何多路复用到单个 SER/DES 链路上的？

    我们使用 Maxim 公司的 SER/DES (GMSL)。

    我们将 2 个摄像头连接到 SER 和 DES、并通过虚拟通道将它们传输到 AM62A。

    [/报价]

    只要传感器驱动程序和串行器/解串器正确管理虚拟通道、就应该可以做到这一点。

    “media-ctl -p“日志对我来说看起来不错、但对于 video3 和 video4、yavta 日志似乎都显示了以下内容：

    输出最初应该是怎样的？

    新发现的症状是当执行 video4 时、video3 也会运行。

    但是、在上述情况下、仅靠 video3 不起作用。

    当 gstreamer 命令单独运行时、video4 起作用、但 video3 不起作用。

    但是、如果同时运行 video3 和 video4、则可以输出。

    您好、Xu

    添加 VC 通道 2 后、我在 subdev 中收到启动错误、如下所示。

    是否有需要检查的要点？

    新发现的症状是当执行 video4 时、video3 也会运行。

    但是、在上述情况下、仅靠 video3 不起作用。

    [/报价]

    您使用的是哪个 SDK 版本？ 您是否有具有 3 个虚拟通道的传感器、或者是否有 3 个传感器？

    您是如何设置媒体设备拓扑的？ 您是否可以尝试不使用 DMA 上下文 0？ 另一个字、请勿使用 “30102000.ticsi2rx context 0“并 从  “30102000.ticsi2rx context 1“开始。

    你（们）好

    我使用的是 SDK 版本 10.01.00.05。

    我总共使用 3 个传感器。

    以上症状是使用 2 个传感器进行测试的结果。

    我计划未来使用 3 个传感器。

    我提到了媒体设备拓扑的 setup_scripts.sh 文件 ov2312 设置。

    在迁移到 30102000.ticsi2rx 上下文 1 后、我将节点更改为 video4、video5。

    但症状与以前相同。

    尊敬的 Kim：

    我总共使用了 3 个传感器。
    我提到了媒体设备拓扑的 setup_scripts.sh 文件 ov2312 设置。

    OV2312 是一款具有 2 个虚拟通道的单个传感器。 请按照/opt/edgeai-gst-apps/scripts/setup_cameras.sh.中的 IMX390 示例进行操作 如果您有多个 IMX390 传感器、则此脚本应按如下所示进行设置： 

    root@am62axx-evm:/opt/edgeai-gst-apps# media-ctl -p
Media controller API version 6.6.32

    总体结构如下。

    您提供的 media-ctl -p 日志显示、两个系列器件中的每个器件都连接了一个传感器。  

    这是正确的吗？

    我再次更改了配置并将上下文更改为 1。

    视频 5 和 6 独立工作,但 4 仍然有相同的症状。

    视频 4、5 和 6 在配置为单个通道时工作正常、因此似乎正在检测 VC-ID。
