您好！

硬件环境 ：orin agx核心模组32G， 底板为定制板。 3xmax96712+ 12x96717（带ISP的相机）

软件环境 ：JP6.2.2

我这边是定制板orin agx，设备树基于0004 官方的设备树修，其中tegra234-p3737-0000+p3701-xxxx-nv-common.dtsi包含了

include “nv-soc/tegra234-overlay.dtsi”
include “nv-soc/tegra234-soc-audio-dai-links.dtsi”
include “nv-soc/tegra234-soc-camera.dtsi”
include “tegra234-p3737-0000.dtsi”
include “tegra234-dcb-p3737-0000-p3701-0000.dtsi”
include “overlay/tegra234-camera-max96712.dtsi”

其中tegra234-camera-max96712.dtsi附件所示。目前像是设备树配置有问题，麻烦帮看下，谢谢。

日志如下：目前相机只插了四个，插到第二组，i2c3这组。

问题1： probe跑完发现节点未注册。

问题2： 前面还有一些vi相关的报错。我这边一个解串器配置的一组4lane mipi，4个虚拟通道，麻烦帮看下设备配置是否正确，谢谢。

Dump the device tree to check.

sudo dtc -I fs -O dts -o extracted_proc.dts /sys/firmware/devicetree/base

我把tegra234-p3737-0000+p3701-0000-dynamic.dts 里边的tegra234-p3737-camera-modules.dtsi去掉了，目前节点注册成功了，但拿不到图。

之前应该是overlay层覆盖掉了，我这边的设备树

The log shows didn’t receive any validate data from the sensor.

You may need probe the signal by scope to confirm it.

Thanks
