      我觉得没有这个必要。
      另外你在i2c-7上面挂了两个相机?即便是这样,也没有必要做两个完全一致的ko插入到系统里面去。

      另外,你所提的图像阻塞的问题。你需要检查一下:1. 硬件的mipi信号线是否跟dts配置的一致。 2. 芯片内的数据通路配置是否正确。

      我建议你先参考我们的资料,搞通一个,然后再类比搞通另一个相机。

        我现在只在设备树添加一个相机,设备树中对相机时钟有要求吗?

          没有要求,相机自己有时钟。
          OK3588-C-Camera.dtsi中,i2c-7这一路,你可以参考一下下面这部分代码。

            @veye_xumm请问,你们调试的时候有遇到这种情况吗?没有数据流输出,一直阻塞 16a1f873-dc28-49a3-9b52-47e9ce0a76fb-image.png

              @lin 你是否用的是外触发模式?
              查看一下dmesg是否有报错?
              确认一下dts中关于mipi接口配置是否正确。

                还有您说的mipi接口配置是指链路设置还是mipi_csi2节点设置?

                  整个数据通路都得配置好才行。

                      看你的拓扑图:

                      你这边设定i2c-7接口配套的mipi硬件接口是:csi2-dphy1
                      真的是这样的吗?

                      我给你的我们调过的那个dts,用的可是csi2-dphy0啊!

                                OK3588-C这个开发板,我之前贴的这个dts是调试过的。

                                没有要求,相机自己有时钟。

                                OK3588-C-Camera.dtsi中,i2c-7这一路,你可以参考一下下面这部分代码。

                                你直接用这个dts,然后配合我们官方发布的驱动。
                                在加上这个链接提示的问题点:https://wiki.veye.cc/index.php/FAQ_on_RK35xx_Platform/zh

                                应该可以直接调通i2c-7这一路才对。

                                        应该跟这个没关系。

                                        你这个命令也没有问题。

                                        很奇怪,按理说应该不会有这些mipi协议上的错误,请拍一下你的硬件系统图给我看看。

                                            确认下这个3.3V是否稳定输出(幅值>3.2V)。100mA@1.2V(或1.5V)看起来功率是不够用的。
