@lin 你的图片我看不到。但是根据你的描述，似乎没有更新dtb。
另外我们提供了一个现成的镜像，在这个链接：

@veye_xumm
请问，我们烧录ROC-RK3588S-PC_Ubuntu20.04-Gnome-r30028_v1.1.1b_230914.img这个镜像，然后添加veye_mvcam.ko进去，怎么还是没有mediax节点和videox节点？不是加载的这个驱动吗？

@lin 从我们相机的角度来看，ar0234m是支持修改i2c地址的，在一个i2c bus上挂载也没有问题。虽然你这个用法比较特别吧。

mvcam1 7-003b: Error applying setting, reverse things back

我觉得你还是得从这个报错入手去找一下。

@veye_xumm 将两个相机节点分别放在i2c3和i2c7节点下，用同一个时钟，内核信息可以检测到两个驱动，没有报错，i2c7下的相机可以正常使用，为什么两个相机不可以使用同一个i2c7节点？

@lin
从这一部分看的话，clk是用的同一个。我不确定rk的驱动逻辑中，这个会不会引起问题。
你可以改成不同的尝试一下。

驱动源码，确定一下问题
你好，这个我们现在不确定是是驱动问题还是设备树的问题，设备树代码如下，麻烦帮忙看一下
设备树修改：

看起来你的dts触发了一个错误，这个错误是camera相机外的驱动报出的。建议你根据这错误，驱动源码，确定一下问题。

@veye_xumm 我们做了扩展pcb板，将4通道的dhpy0关闭，扩展成2个两通道的dphy1和dphy2，两个相机单独使用都是可以的，都是连接两个提供的ar0234m驱动就会报错，报错代码如下：

@lin
roc-rk3588s-pc 这个板子只有一个mipi接口，无法支持两个摄像头啊。
