      @ff1211 我认为树莓派网站上现在最新的pios版本即可。

        @veye_xumm 您不是说要移植dts文件?这块编程我也不会呀。

          @ff1211 升级操作系统到已经提供了dtbo的版本,不需要移植dts。

            @veye_xumm 我现在用的就是最新版的树莓派系统5.15.61-v7l+,对于我来说用rpi-5.10.103是倒退。同时,我上面的截图就是您5.15.61-v7l+ release里面的,并没有这个cm4的文件。您说有两条路,第一是用rpi-5.10.103系统;第二自己移植dts。我不会移植dts所以我选择换系统。但是现在官网上最新的树莓派系统是5.15.61-v7l+,我不知道去哪里下载rpi-5.10.103,所以我问您去哪里下载这个系统。

            此外,第二个问题,我之前按照安装一个摄像头的教程在cm4上安装了驱动,输入dmesg | grep mvcam后显示如下信息:

            我相机接的是cam0接口,/dev中的video设备是从video10开始的,没有video0。

              @ff1211 不好意思,版本的问题我搞错了,需要rpi-5.15.y目录下,模仿现在307的那个做法做一个mv的。
              第二个问题,

              建议你装到camera1接口上去,这个对应的i2c-10的。

                @veye_xumm 我不知道怎么做这个mv的,所以我才问您怎么换系统。或者如果可以的话,麻烦您上传一个吧。

                      @ff1211 研发进度略有推迟,晚一两天。

                            @veye_xumm 您好,我按照您新发的驱动安装了,但是只能探测到一个摄像头。

                                上面那些带注释的是昨天尝试的,今天重新编译安装了下驱动后就被自动注释掉了。下面这个最后一行是我刚加的,加完重启之后还是这个问题。

                                  @ff1211 6.8.1章节的执行了吗? 有没有/dev/i2c-0设备文件?

                                      我看到了这步,如果写-y 10的话确实0x3b那里有个“UU”,但是改成-y 0的话就什么都没有输出。
                                      95317efd-0356-4e43-9437-7a8191b871b6-image.png

                                      会不会是这个问题。

                                        @veye_xumm 我检查了下供电和连线,都正常的,我认为应该可以排除硬件问题。
