      我是把树莓派4b上的系统镜像到CM4上面,用扩展板CM4-IO-BASE-A,摄像头运行正常;

      但是用扩展板CM4-NANO-A,就发现不了摄像头;

          CM4-NANO-A这个板子,好像是只连出了一个CSI接口。
          需要判断一下引出的是哪个csi口。
          你可以用

          i2cdetect -y - 10
          i2cdetect -y - 0
          

          看一下哪个能找到0x3b?

              我现在又重新安装了系统,添加驱动后,不认摄像头了;
              板子跟摄像头不动,用老卡上的系统能连上摄像头

                你的新卡和老卡有啥区别?
                新卡上,执行dmesg | grep mvcam看看输出如何?

                  nano-a 不支持 bullseye ;说这个有bug;
                  支持buster系统,所以我又在新sd卡上灌了5.10.103-v7l系统,安装驱动后,不认摄像头,就是上一楼的提示,我把老sd卡换上去,树莓派跟摄像头都没动,摄像头是正常的

                      你这个驱动的版本有点老了,不识别264这个型号。因为我们研发开发完成一个新的camera之后,往往只在较新的OS版本上编译出ko。
                      最好结合代码重新编译一个ko出来。

                            我先试一下吧,不行的话,还需要你们帮忙编译一下驱动

                                看起来是kernel版本中.remove函数原型定义的差异导致的。你用这个函数替代掉原代码中的对应函数。

                                static int mvcam_remove(struct i2c_client *client)
                                {
                                	struct v4l2_subdev *sd = i2c_get_clientdata(client);
                                	struct mvcam *mvcam = to_mvcam(sd);
                                
                                	v4l2_async_unregister_subdev(sd);
                                	media_entity_cleanup(&sd->entity);
                                	mvcam_free_controls(mvcam);
                                
                                	mutex_destroy(&mvcam->mutex);
                                    return 0;
                                }

                                    在5.10.103-v7l+上安装好了驱动,在base-a上跟4b上都能正常调用了,但是换成nano-a扩展板,就连接不上摄像头

                                          现在i2c0和i2c10都检测不到摄像头,那么有两种可能:

                                          1. 没有给摄像头供电。—— 这种加上供电即可解决。
                                          2. 微雪的这个底板,在i2c硬件方面跟树莓派官方的不同。你需要根据微雪这个板子,改一下设备树文件dts,编译成dtb才可以。

                                            供电我量了一下J3连接器的1、2脚;电压是4.98V;
                                            设备树文件dts怎样修改有没有教程或说明,我好参考一下;我问了微雪的技术他们连imx219摄像头没有问题
