      添加两个设备树节点,ox3b和0x3c,每次只能加载到其中一个摄像头

      怎么回事呢?应该如何加载两个摄像头呢

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

          @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:

            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。

              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:

                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。

                  @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。

                    我觉得你还是得从这个报错入手去找一下。

                      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 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:
